A subtractive cDNA library was developed to study genes associated with bud dormancy release in tree peonies. In order to identify genes that are highly expressed in buds released from dormancy, 588 clones were examined by differential screening. Of these, 185 clones were selected to be sequenced. A total of 37 unique sequences were obtained of which only 31 sequences have matches in the NCBI database or the Arabidopsis thaliana protein database. Semi-quantitative RT-PCR was used to confirm further the expression profiles for 12 transcripts identified within the subtractive cDNA library. Gene ontology analyses indicated that many of the different genes identified have unknown or hypothetical functions while it is speculated that other genes play different mo- lecular roles. In our study, genes involved in bud dormancy release were growth-related or stress-responsive, while low-temperature-induced ribosomal proteins may also play a role in bud dormancy release. Our results provide interesting information for further understanding of the molecular mechanism of bud dormancy release in tree peonies. 展开更多

Its propagation is via vegetative methods. Mech- nisms of the adventitious rooting and the regulation of rooting processes are the principles and techniques of plant propagation and improvement. Microstructures and fluctuations of phytohormones in the adventitious rooting were studied with the etiolated soft- wood shoots of Paeonia suffkuticosa 'Yinfen Jinlin'. There are no pre-primordia in the shoots of the cultivar. Adventitious roots are produced in five stages: shoot selection, primordium initiation, primordium growth, conducting tissue differentiation and root protru- sion. Primordia initiated in the cortex. The contents of the endogenous hormones, IAA, ABA and GA, were 5.842, 0.873 and 1.043 nmol·g^-1 FW on the bases of shoots, respectively. CTKs which included isopentenyl adenine (iPA), zeatin riboside (ZR) and dihy- drozeatin riboside (DHZR) were 0.949, 0.695 and 2.034 nmol·g^-1 FW, respectively. DHZR is active among CTKs. The ratio of IAA to GA, CTK and ABA clearly increased at the stage of primordium initiation, while they showed low levels at the stages of primor- dium growth. The ratios were restored at the shoot levels at the stage of root protrusion. IBA provoked primordia initiation in the cortex, the vascular cambium, the pith and even in the callus induced on the base of shoots. ]AA levels in the treated shoots increased gradually to its highest level (three times of control) at the stage of conducting tissue differentiation. The ratios of IAA to GA, CTK and ABA clearly decreased at the stage of primordium initiation. The ratio of IAA to ABA is regulated at 10:1. 展开更多

The last step of ethylene biosynthesis in higher plants is to convert 1-aminocyclopropane-1-carboxylic acid (ACC) to ethylene by ACC oxidase (ACO). In our investigation, a cross-introns genomic DNA gene encoding ACC oxidase, PsgACO, was isolated from Paeonia suffruticosa. It revealed that PsgACO (FJ855434) has 1281 bases, containing four exons and three introns, en- coding 312 amino acids. The four exons stretched from 1 to 105, 217 to 434, 592 to 925 and 1000 to 1281 bases. A splicing junction sequence of all the exon-introns conformed to the GT-AG rule in the cross-intron genomic DNA sequence of the ACO gene. PsgACO showed high homology to many characterized ACC oxidases both at the nucleic acid and amino acid levels. As well, twelve amino acid residues were conserved among many ACOs from other species. A phylogenetic tree analysis indicated that the amino acid of ACOs is quite conserved among the different eudicots. The phylogenetic tree showed that both the tree peony and herbaceous peony are quite isolated taxa. Bioinformatic analysis showed that the molecular weight of ACO is 35.29 kD, with a theoretical pI of 5.25. It is a non-secrete, stable hydrophilic protein, located in the cytoplasm. 展开更多

In order to reveal the differences between different peony varieties and facilities,thousands of tissue culture seedlings of 21 Itoh peony varieties imported from abroad were used as test materials,and the peony domestication cultivation method used in the past was used as a control. The technical measures and mechanisms for the outdoor domestication of seedlings and the survival of field transplantation were studied. The results indicate that the main factors and measures for effectively protecting the outdoor transplanting of tissue culture seedlings include cultivating sound and strong seedlings,transplanting in proper period of spring,and providing good ventilating places and facilities,removing leaves,keeping buds and releasing dormancy before transplantation,planting depth should meet the requirement of exposing to the root neck,changing the pots according to the size of seedlings,the substrate should be loose and permeable,seriously disinfected and sterilized,scientific management,and prevention and control of diseases and insect pests. In addition,the survival mechanism was also analyzed,and the reasons and countermeasures for the successful application of peony tissue culture in China were found. Finally,the differences in survival rates between different varieties and facilities were summarized. 展开更多

Objective:Research the chemical constituents of Paeonia suffruticosa that are responsible for its anti-infective properties.Methods:Several column chromatographic methods were used to purify the chemical constituents from P.suffruticosa,including medium pressure liquid chromatography,Sephadex LH-20,and normal silica gel.A disc diffusion method was used to screen for antibacterial activity,and their anti-virulence activity was assessed on the type III secretion system(T3SS)of Salmonella pathogenicity island 1(SPI-1)in Salmonella enterica serovar Typhimurium UK-1 g 8956 by SDS-PAGE and western blots.Results:Twenty-one compounds were identified.Compounds 7,8 and 17 showed moderate activity against S.aureus ATCC25923,compounds 8,9 and 10 showed weak activities against B.subtilis ACCC11060.Meanwhile,phenols(14-18)and flavonoids(20 and 21)inhibited T3SS protein secretion of S.typhimurium without affecting bacterial growth.Furthermore,a strong inhibitory effect was observed for 17 and 20 on SPI-1 mediated invasion of HeLa cells.Additionally,no toxicity was observed for these compounds.Conclusion:P.suffruticosa has anti-infective properties due in part to the fact that phenols and flavonoids can block the secretion of T3SS-associated protein effectors. 展开更多

利用农业废弃物稻壳和混合秸秆部分替代配方基质中泥炭,探究添加农业废弃物配方基质在牡丹(Paeonia suffruticosa Andr.)不同生长期的理化性质、水解酶活性以及碳(C)、氮(N)、磷(P)和水解酶活性的化学计量比的变化特征,分析基质的理化... 利用农业废弃物稻壳和混合秸秆部分替代配方基质中泥炭,探究添加农业废弃物配方基质在牡丹(Paeonia suffruticosa Andr.)不同生长期的理化性质、水解酶活性以及碳(C)、氮(N)、磷(P)和水解酶活性的化学计量比的变化特征,分析基质的理化性质和C、N、P化学计量比以及牡丹外部形态指标与基质水解酶活性相关指标的相关性,并对牡丹外部形态特征进行综合评价。结果表明:从牡丹开花期至花芽分化期,与CK〔V(泥炭)∶V(珍珠岩)∶V(蛭石)=6∶2∶2〕配方基质相比较,T1〔V(泥炭)∶V(珍珠岩)∶V(蛭石)∶V(稻壳)=5∶2∶2∶1〕和T2〔V(泥炭)∶V(珍珠岩)∶V(蛭石)∶V(混合秸秆)=5∶2∶2∶1〕配方基质的全磷含量、铵态氮含量和β-1,4-N-乙酰氨基葡萄糖苷酶活性显著(P<0.05)升高,C/P比和N/P比总体显著下降,氮磷酶活性比(ENP)总体升高。从牡丹开花期至花芽分化期,3种配方基质中微生物受到的P限制转变为N限制,C限制逐渐加剧。其中,在开花期,T1和T2配方基质缓解了微生物受到的P限制;在开花期和叶片生长期,T1配方基质缓解了微生物受到的C限制;在花芽分化期,T1配方基质加剧了微生物受到的C限制。T1和T2配方基质中牡丹的最小叶宽和最小叶长总体较CK配方基质显著增加。总体上看,从牡丹开花期至花芽分化期,3种配方基质的pH值、含水量、β-1,4-葡萄糖苷酶活性、亮氨酸氨基肽酶活性、β-1,4-N-乙酰氨基葡萄糖苷酶活性、碳磷酶活性比(ECP)和ENP呈升高趋势,有机碳含量、全氮含量、铵态氮含量、C/N比、C/P比和N/P比呈先降低后升高的变化趋势,硝态氮含量呈降低趋势,碳氮酶活性比(ECN)呈先升高后降低的变化趋势。冗余分析结果显示牡丹外部形态指标受基质C/N比、ECN和ENP的显著影响。T1配方基质中牡丹外部形态指标的综合评价指数最高(0.82)。综上所述,稻壳部分替代泥炭用于牡丹的栽培基质增加了基质的全磷含量、铵态氮含量和β-1,4-N-乙酰氨基葡萄糖苷酶活性,明显缓解了P限制,提高了牡丹植株的综合性状,适宜部分替代泥炭作为牡丹的生长基质。 展开更多
