Polyploidy Induction and Morphological Characteristics in the Asiatic Hybrid Lily(Lilium spp.cultivar dazzling)

The Asiatic hybrid lily cultivar Lilium dazzling(family Liliaceae)is a perennial herbaceous bulbous plant with bright yellow flowers of ornamental values.It also shows resistance to diseases and abiotic stress,making it an ideal parent for breeding studies.This study established a sterile culture system using scales of dazzling lily as explants to induce polyploidy.Adventitious buds growing to 1 cm were treated with different concentrations of colchicine(125,250 and 500μmol·L-1),pendimethalin or trifluralin(100,200 and 300μmol·L-1,respectively)for 12,24 and 36 h.Flow cytometry and chromosome counting were used to identify ploidy,and the phenotype of the polyploids was examined by stomatal observation and leaf index determination.With increasing mutagen concentration and exposure time,the mortality and mutagenic rate increased.The optimal treatment group was:300μmol·L-1 trifluralin for 12 h,which resulted in 15.55%mortality rate and 42.22%induction rate.The polyploid plants showed a significant increase in stomata length,leaf length and leaf width,with a decrease in stomatal density compared with the control plants.This study provided a basis for polyploid breeding.

Transcriptomic and physiological analyses identifying Lanzhou lily(Lilium davidii var.unicolor)drought adaptation strategies

Drought stress is the main limiting plant growth factor in arid and semiarid regions.The Lanzhou lily(Lilium davidii var.unicolor)is the only sweet-tasting lily grown in these regions of China that offers highly edible,medicinal,health,and ornamental value.The Tresor lily is an ornamental flower known for its strong resistance.Plants were grown under three different drought intensity treatments,namely,being watered at intervals of 5,15,and 25 d(either throughout the study or during specific growth stages).We measured the biomass,leaf area,photosynthetic response,chlorophyll content(SPAD value),and osmoregulation of both the Lanzhou lily and the Tresor lily(Lilium‘Tresor’).Additionally,we employed RNA sequencing(RNA-Seq)and qRT-PCR to investigate transcriptomic changes of the Lanzhou lily in response to drought stress.Results showed that under drought stress,the decreasing rate in the Lanzhou lily bulb weight was lower than the corresponding Tresor lily bulb rate;the net photosynthetic rate,transpiration rate,and stomatal conductance of the Lanzhou lily were all higher compared to the Tresor lily;osmoregulation constituents,such as glucose,fructose,sucrose,trehalose,and soluble sugar,in the Lanzhou lily were comparatively higher;PYL,NCED,and ERS genes were significantly expressed in the Lanzhou lily.Under moderate drought,the biosynthesis of flavonoids,circadian rhythms,and the tryptophan metabolism pathway of the Lanzhou lily were all significant.Under severe drought stress,fatty acid elongation,photosynthetic antenna protein,plant hormone signal transduction,flavone and flavonol biosynthesis,and the carotenoid biosynthesis pathway were all significant.The Lanzhou lily adapted to drought stress by coordinating its organs and the unique role of its bulb,regulating photosynthesis,increasing osmolyte content,activating circadian rhythms,signal transduction,fatty acid elongation metabolism,and phenylalanine and flavonoid metabolic pathways,which may collectively be the main adaptation strategy and mechanisms used by the Lanzhou lily under drought stress.

GAMYB transcription factor LoMYB65 from lily plays a vital role in pollen development

Lily(Lilium spp.)is an important horticultural crop,but its use is limited due to serious pollen contamination problems.There are many studies on pollen development in model plants,but few on flower crops such as lilies.Gibberellin(GA)is a large class of hormones and plays an important role in plant vegetative growth and reproductive development.GAMYB is a group of the R2R3-MYB family upregulated by gibberellin,and plays an important role in anther development.Here,we isolated a novel GAMYB,named LoMYB65,from lily,which was closely related to the AtMYB65 and AtMYB33 in Arabidopsis.Fluorescence quantitative PCR results showed that LoMYB65 was mainly expressed in lily anthers.LoMYB65 could be activated by 288μmol·L^(-1)GA3treatment and the LoMYB65 protein was located in the nucleus and cytoplasm,and had transactivation in yeast and tobacco leaf cells.The conserved motif within 226 amino acids of the C-terminal of LoMYB65 contributed to its transactivation.Overexpression of LoMYB65 caused dwarf phenotype,unnormal tapetum development,less seeds of siliques in transgenic Arabidopsis plants,the transgenic plants showed partly male sterile.Simultaneously,silencing of LoMYB65 with VIGS(Virus Induced Gene Silencing)in lily anthers caused unnormal pollen development and reduced the pollen amount.Overexpression of LoMYB65 in Arabidopsis and silencing of LoMYB65 in lily resulted in decreased pollen counts,so we speculate that LoMYB65 may be dose-dependent.Overall,these findings suggest that LoMYB65 may play an important role in anther development and pollen formation in lily.LoMYB65 may provide a useful candidate gene for pollenless breeding of lily.

Effects of intercropping on rhizosphere soil microorganisms and root exudates of Lanzhou lily(Lilium davidii var.unicolor)

Both yield and quality of Lanzhou lily(Lilium davidii var. unicolor) are seriously affected by continuous cropping. We attempted to understand the effects of intercropping on the obstacles associated with continuous cropping of Lanzhou lily(Lilium davidii var. unicolor). The changes of rhizosphere microbial biomass and diversity in interplanting and monoculturing systems were studied by using the Illumina Hi Seq sequencing technique. The contents and composition of lily root exudates were measured by gas chromatography–mass spectrometer(GC–MS). The intercropping results of Lanzhou lily showed:(1) There was no difference in the composition of the rhizosphere soil microbes at the phylum level, but the relative abundance of the microbes decreased; and the relative abundance of harmful fungi such as Fusarium sp. increased. The relative abundance of Pleosporales sp. and other beneficial bacteria were reduced. After OTU(operational taxonomic unit)clustering, there were some beneficial bacteria, such as Chaetomium sp., in the lily rhizosphere soil in the interplanting system that had not existed in the single-cropping system. We did not find harmful bacteria that had existed in the single-cropping systm in the rhizosphere soil of interplanting system. The above results indicated that the changes of relative abundance of soil fungi and bacteria in lily rhizosphere soil was not conducive to improving the ecological structure of rhizosphere soil microbes. At the same time, the microbial composition change is very complex—beneficial and yet inadequate at the same time.(2) Root exudates provide a matrix for the growth of microorganisms. Combined with the detection of root exudates, the decrease in the composition of the root exudates of the lily was probably the reason for the decrease of the relative abundance of microbes after intercropping. At the same time, the decrease of the relative content of phenolic compounds, which inhibit the growth of microorganisms, did not increase the relative content of rhizosphere soil microorganisms. Changes in amino acids and total sugars may be responsible for the growth of Fusarium sp.. The results showed that the intercropping pattern did not noticeably alleviate the obstacle to continuous cropping of Lanzhou lily, and the change of microbial biomass and diversity was even unfavorable. However, the emergence of some beneficial bacteria, the disappearance of harmful fungi, and other changes with intercropping are in favor of alleviation of obstacles to continuous cropping of Lanzhou lily.

Isolation of LiLFY1 and Its Expression in Lily (Lilium longiflorum Thunb.)

LFY family genes play a conserved role in regulating flowering. In this study, the cDNA of LiLFY1 was isolated with the strategy of RT-PCR in combination with RACE from lily （Lilium longiflorum Thunb.）. LiLFY1 encodes a LFY transcriptional factor. The alignment analysis of the deduced LiLFY1 protein with other known LFY family proteins indicates that LiLFY1 is highly homologous with rice RFL and maize FLL. The result of Southern hybridization showed that there are two copies of LFY family genes in lily. LiLFY1 is expressed in young flower buds and shoot apical meristem （SAM） but not in roots, shoots, mature leaves, and mature floral organs. The cloned LiLFY1 gene may be applied to genetic engineering aiming for regulating the flowering time in lily.

Comparative transcriptome and proteome analysis of lily clones inoculated with Fusarium oxysporum f. sp. lilii

Basal bulb rot is the major factor restricting the production of lily,caused by Fusarium oxysporum f.sp.lilii.To systematically analyze the transcriptomic and proteomic responses of lily clones to F.oxysporum,we constructed six RNA-seq libraries and four iTRAQ proteomic libraries using lily resistant and susceptible clones sampled at 0,24 and 48 h post-inoculation(hpi)with F.oxysporum respectively.137,715 unigenes were generated,of which 7,667 were differentially expressed.1,679 and 4,051 differentially expressed genes(DEGs)between resistant and susceptible clones were isolated from samples collected at 0 and 48 hpi.Four hundred and thirty three and 155 DEGs were identified in resistant clones sampled at 24 and 48 hpi separately while 550 and 799 DEGs were isolated in the susceptible clones sampled at 24 and 48 hpi respectively.The results of iTRAQ analysis revealed 7,482 proteins in resistant and susceptible clones.Data analysis of transcriptome and proteome indicated that 5,735 proteins corresponded to mRNAs.Three hundred and sixteen and 1,052 DEGs had corresponding DEPs.At 48 hpi,the resistant clones showed 155 DEGs and 108 corresponding DEPs,while the susceptible clones showed 799 DEGs and 316 corresponding DEPs.In general,these results enhance comprehension of the defense response of lily resistant clones to F.oxysporum infection and provide valuable sequence data for studying the resistance mechanism.

Genetic Diversity of Five Different Lily(Lilium L.)Species in Lithuania Revealed by ISSR Markers

To study the genetic diversity and structure of lily (Lilium L.), we collected 35 samples from Vytautas Magnus University Kaunas Botanical Garden, and analyzed their mutual Simple Sequence Repeat (ISSR) molecular markers. For genetic analysis of lily we chose the lily 6 markers. ISSR data revealed a relatively high level of genetic diversity at the different levels of the group, with 95% of polymorphic loci, effective number of alleles of 1.21, the average expected heterozygosis of 0.15 and Shannon’s information index of 0.26. ANOVA analysis and UPGMA-dendrogram suggested a hierarchical structure between species.

Tissue Culture of Calla Lily (Zantedeschia spreng.): An Updated Review on the Present Scenario and Future Prospects

The calla lily(Zantedeschia spreng.)is a bulbousflower native to the tropical regions of Africa.Calla lily has gained significant popularity in the international market owing to its intricate morphology and prolonged flowering duration.Despite such advantages,for two sub-groups of calla lily,known as group Zantedeschia and group Aestivae,there are challenges in terms of hybrid production due to the‘plastome-genome incompatibility’there-between.Tissue culture is a fundamental biotechnological tool used in gene editing research,with a focus on disease resistance andflower color in calla lily breeding programs.The present review provides a brief background on the history and development of the calla lily,as well as a comprehensive and critical summary of calla lily tissue culture research.The regeneration pathways for both group Zantedeschia and group Aestivae can be divided into de novo organogenesis and somatic embryogenesis.Both groups are capable of obtaining replants through such means.However,only some species in group Aestivae have been reported to be successful in the somatic embryogenesis pathway.In the present review,special attention was paid to the influence of explant types,plant growth regulators,and culture conditions on both de novo organogenesis and somatic embryogenesis in calla lily tissue culture.Ultimately,future research prospects were determined based on integrated analysis of recent progress in calla lily tissue culture research.
