Agrobacterium tumefaciens-mediated transformation of modern rose(Rosa hybrida)using leaf-derived embryogenic callus

Rose(Rosa hybrida)is widely used for cut flowers and as garden plants.Stable and efficient transformation system is required for functional genomics of rose.Here,we established an efficient transformation method for rose using Agrobacterium tumefaciens-mediated transformation of embryogenic callus.Expanding rose leaves were used as explants to induce somatic embryos,which were subjected to transformation with A.tumefaciens strain GV3101 using Green Fluorescence Protein(GFP)as a marker gene.It took about 8 months to generate transgenic shoots from embryogenic callus.PCR,RT-PCR,Southern and Western blotting,as well as stereoscopic fluorescence microscopy analysis demonstrated that GFP transgenes integrated stably into the rose genome.According to our data,a transformation efficiency of up to 6%can be achieved by following this optimized protocol.

Antimicrobial Effectiveness on Selected Bacterial Species and Alkaloid and Saponin Content of <i>Rosa nutkana</i>C. Presl (Nootka Rose) and <i>Urtica dioica</i>L. (Stinging Nettle) Extracts

Nootka rose (Rosa nutkana C. Presl) and stinging nettle (Urtica dioica L.) have been traditionally used in the treatment of skin infection by Indigenous peoples of Vancouver Island, British Columbia, Canada. The main objective of this study was to examine the antibacterial efficacy of extracts of Nootka rose and stinging nettle against the common pathogenic skin bacteria Staphylococcus aureus, Micrococcus luteus, and Pseudomonas aeruginosa using Indigenous science and standard methods of analysis. The Indigenous science method of plant extraction by steeping as advised by the Traditional Knowledge keeper was performed to examine minimum inhibitory concentration (MIC) values and minimum bactericidal concentrations (MBC) by serial dilution and bacterial population counts. Soxhlet extractions and Kirby Bauer disc sensitivity testing showed that Nootka rose extracts possessed antibacterial effectiveness against all three bacterial species while stinging nettle extracts were effective against M. luteus. Results for MIC and MBC indicated antibacterial activity against M. luteus and S. aureus for the Nootka rose when using full-strength solutions;all three bacterial species exhibited growth when undiluted stinging nettle treatments were used. When considering bacterial population counts for S. aureus, results indicated that only the Nootka rose treatment offered effective inhibition. Chemical analysis showed that alkaloid percentage was greater in the stinging nettle (0.17%) than Nootka rose (0.07%), while saponin percentage was greater in the Nootka rose (0.87%) than stinging nettle (0.17%). Overall, Nootka rose showed a greater level of antibacterial effectiveness than stinging nettle by Indigenous and Western scientific methods of plant extract preparation.

The Potentiality of Non Timber Forest Products. Fruit Availability, Phytochemical Properties of Rosa rubiginosa L. Rose Hips

We evaluated fruit availability, phytochemical characteristics and mineral content of R. rubiginosa L. rose hips, at two experimental sites in San Luis province: Potrero de los Funes-El Volcán (PF-V) and Estancia Grande (EG). Plant density was 70 plants/ha (1 ha = 10,000 m2) in PF-V and 50 plants/ha in EG. Fruit availability (DF) in fresh fruits (FF) was 4.39 kg (PF-V) and 3.10 kg (EG) during March, and decreased during June. Ascorbic acid in FF increased during ripening period, peaking on late April, early May, and diminished 75% - 85% in dried fruits. Total soluble solids in FF ranged from 32.55 to 55.20 °Brix. Elements Ba, Ca, Fe, K, Zn and Cu, determined by inductively coupled plasma optical emission spectrometry (ICP-OES), were significant for human health. Dried fruits maintain a high level of ascorbic acid, a characteristic added to content of mineral elements, particularly calcium content, providing an important nutritional value to R. rubiginosa rose hips.

The RhHB1/RhLOX4 module affects the dehydration tolerance of rose flowers(Rosa hybrida)by fine-tuning jasmonic acid levels

Phytohormones are key factors in plant responsiveness to abiotic and biotic stresses,and maintaining hormone homeostasis is critically important during stress responses.Cut rose(Rosa hybrida)flowers experience dehydration stress during postharvest handling,and jasmonic acid(JA)levels change as a result of this stress.However,how JA is involved in dehydration tolerance remains unclear.We investigated the functions of the JA-and dehydration-induced RhHB1 gene,which encodes a homeodomain-leucine zipper Iγ-clade transcription factor,in rose flowers.Silencing RhHB1 decreased petal dehydration tolerance and resulted in a persistent increase in JA-Ile content and reduced dehydration tolerance.An elevated JA-Ile level had a detrimental effect on rose petal dehydration tolerance.RhHB1 was shown to lower the transient induction of JA-Ile accumulation in response to dehydration.In addition to transcriptomic data,we obtained evidence that RhHB1 suppresses the expression of the lipoxygenase 4(RhLOX4)gene by directly binding to its promoter both in vivo and in vitro.We propose that increased JA-Ile levels weaken the capacity for osmotic adjustment in petal cells,resulting in reduced dehydration tolerance.In conclusion,a JA feedback loop mediated by an RhHB1/RhLOX4 regulatory module provides dehydration tolerance by fine-tuning bioactive JA levels in dehydrated flowers.

Role of Grafting Technique on the Success of Stenting Propagation of Two Rose (<i>Rosa</i>sp.) Varieties

The influence of two grafting techniques on the success of stenting (simultaneous cutting and grafting) and some ensuing growth parameters of stentlings were studied under glasshouse conditions. The Avalanch and Peach Avalanch glasshouse rose varieties were utilized as scion and grafted on R. manetti as rootstock. Two grafting techniques namely, splice and omega grafting methods were practiced and graft combinations were inserted in cocopeat-perlit (1:2) medium under mist system. The number of roots, longest root size, shoots and leaf numbers and successful grafting percentage were evaluated after grafting. In Avalanch/R. manetti and Peach Avalanch/R. manetti combinations, higher percentage of successful grafting was observed in the stentlings propagated via omega grafting technique. Furthermore Avalanch/R. manetti stentlings prepared by omega grafting were found to produce more number of roots, shoots and leaves and longest root size as compared to those propagated through splice grafting method. In case of Peach Avalanch/R. manetti combinations propagated via omega grafting more number of shoots was observed as compared to those propagated by splice method. However, these were not significantly different with respect to their leaf numbers. The results showed the superiority of omega grafting procedure.

Effect of Rosehip (<i>Rosa Canina</i>) Extracts on Human Brain Tumor Cell Proliferation and Apoptosis

Rosehips are blossoms from the wild rose (Rosa canina) and are commonly used as an herbal remedy. Previous reports have shown that extracts made from rosehip plants are able to reduce cell proliferation of cancer cells. In this study, we investigated the efficacy of rosehip extracts in preventing cell proliferation of three human glioblastoma cell lines A-172, U-251 MG and U-1242 MG cell lines. Each of the glioblastoma cell lines treated with rosehip extracts (1 mg/mL-25 ng/mL) demonstrated a significant decrease in cell proliferation. The rosehip extract-mediated decrease in cell proliferation was equal to or better than the decrease of cell proliferation observed when inhibitors of the MAPK (U0126, 10 μM) or AKT (LY294002, 20 μM) signaling pathways were utilized. Additionally, pretreatment of the these cell lines with Rosehip extracts (1 mg/mL-25 ng/mL) selectively decreased AKT, MAPK, and p70S6K phosphorylation suggesting these extracts prevent glioblastoma multiforme cell proliferation by blocking both the MAPK and AKT signaling mechanisms. Results from colorimetric cell death assays, cell cycle analysis by flow cytometry, as well as western blot studies demonstrate that rosehip extracts inhibit cell proliferation but do not promote apoptosis. Moreover, rosehip extracts were able to increase the efficacy of Temozolomide, a chemotherapeutic agent used to treat patients with glioblastomas. Surprisingly, rosehip extracts demonstrated a greater inhibition of cell proliferation than in combination with Temozolomide (100 μM) or Temozolomide as a single agent. Taken together these data suggest that rosehip extracts are capable of decreasing glioblastoma cell proliferation without promoting apoptosis and demonstrate a greater cell proliferation inhibitory effect than Temozolomide. More importantly, rosehip extracts may serve as an alternative or compliment to current chemotherapeutic regimens for glioblastomas.

A survey on Hibiscus rosa-sinensis,Alcea rosea L.and Malva neglecta Wallr as antibacterial agents

Objective:To guide for selection of plants with antibacterial activity for further phytochemical works on the isolation and identification of the active compounds.Methods:Ethanolic extracts of 3 species from Malvaceae family were evaluated by agar disc diffusion method for antibacterial activity against some gram-positive and gram-negative bacteria(Pseudomonas aeruginosa,Listeria monocytogenes,Staphylococcus epidermidis.Staphylococcus aureus, Klebsiella pneumoniae.Salmonella typhi,Bacillus cereus.Bacillus anthracis,Escherichia coli and Streptococcus pyogenes).The extracts were obtained from aerial parts of Hibiscus rosa(H. rosa)-sinensis(leaf and flower),Alcea rosea(A.rosea) L.(leaf and flower) and Malva neglecta(M. neglecta) Wallr(flower).Results:These extracts had inhibitory effects at different concentrations (0.05,0.10,0.20 and 0.40 g/mL) against above mentioned bacteria.Escherichia coli was the most resistant strain.The highest inhibitory zone was showed by ethanolic extract of M.neglecta against Staphylococcus epidermidis(22 mm) and followed by ethanolic extract from flower of H.rosa against Staphylococcus epidermidis and Staphylococcus aureus(20 mm).The Minimum Inhibitory Concentration(MIC) and Minimum Bactericidal Concentration(MBC) values against Staphylococcus epidermidis were equal(M1C=MBC=5 mg/mL for M.neglecta extract and for H. rosa extract MIC=MBC=20 mg/mL).Conclusions:These findings suggest that these native plants have good antibacterial properties that can be used for infection control and treatment and could also be as new source for antibiotics discovery and infection treatment.

Polygenic Heritability of Rose Root Rot Disease Resistance in Offspring of Rosa multiflora

Rose root rot disease caused by Pythium helicoides Drechsler has brought heavy damage to cut rose production in Japan,and it has became apparent that Rosa multiflora showed resistance to this disease.Roses have been bred by interspecies crossing with Rosa species including of R.multiflora,and many progenies of R.multiflora have been bred as determined cluster-flowered roses.However,the genetic architecture of this resistance remains.So,in this study,four kinds of R.multiflora and 21 rose cultivars that have been clarified in the cross-fertilization genealogy with R.multiflora were used as plant materials,and the inheritability of resistance to root rot disease was investigated.Four kinds of R.multiflora had all high resistance,and the resistance to root rot disease in R.multiflora was inherent characteristic of species.Five varieties not less than 50% in relatedness with R.multiflora were shown as varied ‘resistant’ and ‘moderately resistant’.Therefore,the inherent resistant characteristic in R.multiflora was not controlled by single major gene,and the resistibility in R.multiflora was not cytoplasmic but nuclear heredity.Although there was significant negative relation between relative root rot severity and relatedness with R.multiflora,the variance of relative root rot severity had tendency to expand as relatedness with R.multiflora reduced.This result,therefore,indicated that the contingency of resistance expression increased as the relatedness with R.multiflora was reduced.The varieties having low degree of relatedness with R.multiflora had similar relative root rot severity with R.multiflora.These results indicated that we would be able to select resistant roses from progenies crossed with R.multiflora.

Occurrence Factors and Comprehensive Prevention and Control of Chinese Rose Black Spot(Actinonema rosae)

In addition to conventional techniques,the prevention and control of Chinese rose black spot(Actinonema rosae)should be strengthened in the management of Chinese rose.The occurrence of Chinese rose black spot is closely related to plant residues,rainfall,cultivation conditions and varieties.On the basis of understanding the symptoms and occurrence regularity of Chinese rose black spot,combination measures of agricultural and chemical prevention and control should be taken.

基于ROSE2.0的普洱地区CINRAD/CC雷达冰雹探测算法评估及参数本地化

为提高冰雹探测算法(Hail Detection Algorithm, HDA)产品的可用性,针对2015—2020年普洱地区监测到的22次冰雹个例,利用新一代雷达业务应用软件ROSE2.0对相关雷达基数据进行回放及产品分析,以命中率、虚警率、临界成功指数为指标对HDA算法在普洱地区的识别效果进行评估并给出本地化参数配置方案。结果表明:HDA算法在普洱地区命中率接近100%,但虚警现象非常普遍,使用强冰雹概率(Probability of Severe Hail, POSH)的预警效果优于任意大小冰雹概率(Probability of Hail, POH),且冰雹尺寸越大POSH虚警的概率越低。进一步使用模拟测评法对POSH算法的适配参数进行分析,发现正确输入降雹日当天的0℃层和-20℃层高度能有效减少POSH的虚警率及提高临界成功指数;同时使算法预测的最大冰雹直径普遍偏大的情况得到控制,其中,中小冰雹直径偏离百分比减小76.07%,改善效果显著高于大冰雹。此外,增大反射率因子及POSH阈值能有效控制虚警,但也导致漏报次数快速增加,当阈值太大时命中率明显降低,为了保证较高的命中率和临界成功指数,选择Z=50 dBz或POSH=70%为阈值能明显改善HDA算法的识别效果。

Giorgio Vasari’s Tondo for the Madonna of the Rosary: Angels With Roses, Emblems of Love

In 1569,Giorgio Vasari(1511-1574)completed painting an altarpiece of the Madonna of the Rosary and a Tondo of angels dispersing roses.The commission was for the private chapel of the Capponi family in the church of Santa Maria Novella in Florence.In his Ricordanze(Book of Records),Vasari explained the commission as well as documenting the assistance of his favorite Florentine pupil,Jacopo Zucchi(1541-1590),in the completion of the commission.This essay focusses on Vasari’s design,location,and meaning of the Tondo and its emblematic symbolism of love through the rose motif.

Effect of Modified Biochar with Organic Fertiliser on the Growth and Development of Chinese Rose

In order to reduce the waste of resources and environmental pollution caused by excessive application of chemical fertilizers, improve the utilization rate of fertilizers, and promote the large-scale and high-quality development of the Chinese rose industry. In this experiment, corn stover biochar, phosphoric acid modified biochar and organic fertilizer were used as test materials, and the effects of mixed application of modified biochar and organic fertilizer on the growth and development of Chinese rose as well as soil physicochemical properties were investigated by using the method of pot planting test. The results showed that modified biochar with organic fertilizer had the most significant effect on the enhancement of soil pH, organic matter content and soil carbon-to-nitrogen ratio. After 120 d of planting, modified biochar with organic fertilizer had the most significant effect on the enhancement of plant height and crown width of Chinese rose;both organic fertilizer and modified biochar with organic fertilizer significantly increased the chlorophyll content of Chinese rose. The number of flowers and the number of branches were the highest in the modified biochar with organic fertilizer treatment. In conclusion, the application of modified biochar with organic fertilizer can better improve the soil pH, and increase the soil organic matter content and carbon-to-nitrogen ratio to change the biological traits of Chinese rose. The results of this study provide a theoretical basis for the reduction of chemical fertilizers and the resource utilization of agricultural wastes and guarantee the sustainable development of the cut flower industry.

Effect of fermented Rosa roxburghii Tratt fruit juice on gut microbiota in a dextran sulfate sodium-induced colitis mouse model

This study mainly investigated the regulatory effect of Rosa roxburghii Tratt fruit juice fermented by Lacticaseibacillus paracasei SR10-1(LAB-RRTJ)on modulating gut microbiota in dextran sulfate sodium(DSS)-induced ulcerative colitis in mice.Compared to control group,DSS induction decreased body weight of mice,indexes of Shannon,Simpson,Chao1 and Faith_pd,and increased disease activity index(DAI)and levels of interleukin 1β(IL-1β),IL-6,tumor necrosis factorα(TNF-α)and interferon-γ(IFN-γ);And this induction also led to an increase in Proteobacteria,Verrucomicrobia and Actinobacteria at phylum level,harmful bacterial species richness at genus level,and relative richness of S.sciuri,Desulfovibrio C21_c20,R.gnavus and Akkermansia muciniphila at species level,and a decrease in Firmicutes at phylum level and relative richness of B.acidifaciens in mice.LAB-RRTJ increased body weight of mice with DSS induced ulcerative colitis(UC)and indexes of Shannon,Simpson,Chao1 and Faith_pd,reduced DAI and the content of four infl ammatory factors and improved gut microbiota imbalance in DSS induced UC mice.Besides,the number of operational taxonomic units(OTUs)increased,α-diversity andβ-diversity were restored and similar to those in mice in the control group after LAB-RRTJ treatment.Compared with the positive drug treatment group,LAB-RRTJ has a better effect on regulating gut microbiota diversity in colitis mice.Correlation analysis showed that infl ammatory factors were positively correlated with harmful bacteria and negatively correlated with beneficial bacteria which commonly found in some colitis mice.Taken together,our study demonstrated that LAB-RRTJ could alleviate DSS-induced colitis in mice through the modulation of infl ammatory cytokines and gut microbiota composition.

Identification of key genes regulating the synthesis of quercetin derivatives in Rosa roxburghii through integrated transcriptomics and metabolomics

Rosa roxburghii fruit is rich in flavonoids, but little is known about their biosynthetic pathways. In this study, we employed transcriptomics and metabolomics to study changes related to the flavonoids at five different stages of R. roxburghii fruit development. Flavonoids and the genes related to their biosynthesis were found to undergo significant changes in abundance across different developmental stages, and numerous quercetin derivatives were identified. We found three gene expression modules that were significantly associated with the abundances of the different flavonoids in R. roxburghii and identified three structural UDP-glycosyltransferase genes directly involved in the synthesis of quercetin derivatives within these modules. In addition, we found that RrBEH4, RrLBD1 and RrPIF8could significantly increase the expression of downstream quercetin derivative biosynthesis genes. Taken together,these results provide new insights into the metabolism of flavonoids and the accumulation of quercetin derivatives in R. roxburghii.

Exogenous calcium enhances the physiological status and photosynthetic capacity of rose under drought stress

Drought(water shortage)can substantially limit the yield and economic value of rose plants(Rosa spp.).Here,we characterized the effect of exogenous calcium(Ca^(2+))on the antioxidant system and photosynthesis-related properties of rose under polyethylene glycol 6000(PEG6000)-induced drought stress.Chlorophyll levels,as well as leaf and root biomass,were significantly reduced by drought;drought also had a major effect on the enzymatic antioxidant system and increased concentrations of reactive oxygen species.Application of exogenous Ca^(2+)increased the net photosynthetic rate and stomatal conductance of leaves,enhanced water-use efficiency,and increased the length and width of stomata following exposure to drought.Organ-specific physiological responses were observed under different concentrations of Ca^(2+).Application of 5 mmol·L^(-1)Ca^(2+)promoted photosynthesis and antioxidant activity in the leaves,and application of 10 mmol·L^(-1)Ca^(2+)promoted antioxidant activity in the roots.Application of exogenous Ca^(2+)greatly enhanced the phenotype and photosynthetic capacity of potted rose plants following exposure to drought stress.Overall,our findings indicate that the application of exogenous Ca^(2+)enhances the drought resistance of roses by promoting physiological adaptation and that it could be used to aid the cultivation of rose plants.

The MADS-box gene RhAGL6 plays a master role in regulating the receptacle malformation in rose at low temperature

Low temperature usually results in the developmental deformity of flower organs,immensely affecting the quality of rose flowers.However,it's largely unknown about the regulatory mechanisms activated by low temperature.Here,we used a low temperature-sensitive Rosa hybrida cv.‘Peach Avalanche’to screen a MADS-box gene RhAGL6 via conjoint analysis between RNA sequencing(RNA-seq)and whole-genome bisulfite sequencing(WGBS).Furthermore,we found that low temperature induced the hypermethylation and elevated histone 3 lys-27 trimethylation(H3K27me3)level on the RhAGL6 promoter,leading to decreased RhAGL6 expression.In addition,RhAGL6 silencing resulted in the formation of abnormal receptacles.We also found that the levels of gibberellins(GA3)and abscisic acid(ABA)in the receptacle under low temperature were lower and higher,respectively,than under normal temperature.Promoter activity analysis revealed that GA3 significantly activated RhAGL6 promoter activity,whereas ABA inhibited it.Thus,we propose that RhAGL6 regulates rose receptacle development by integrating epigenetic regulation and phytohormones signaling at low temperature.

An Analysis of A Rose for Emily from the Perspective of Spatial Narrative

The novel A Rose for Emily is one of the early works of William Faulkner,a famous American southern writer who has won The Nobel Prize in Literature in 1950.Spatial narrative theory analyzes and summarizes the spatial characteristics of modern and postmodern novels,showing the narrative characteristics of the works that the time is disrupted and suspended,and the space is extended indefinitely.This paper intends to interpret A Rose for Emily from the perspective of spatial narrative theory,and analyze the geological space,social space and text space in the novel,so as to reveal the important role of spatial structure in creating atmosphere and promoting narrative process,in order to better grasp the spatial metaphors in Faulkner’s novels.
