短童期百合营养生长阶段转变的重要通路筛选
Screening of key candidate regulatory pathways during the vegetative phase change in lily with short juvenile stage
摘要
Abstract
Lily(Lilium spp.)is one of the most representative bulbous flowers.However,the vast majority of lilies have a long juvenile stage,which is a significant bottleneck for the development of the entire production industry.In this study,we analyzed the transition from the juvenile stage to the adult stage of different germplasms and bulblet sizes in lily.Furthermore,using the typical short-juvenile-stage germplasm L.×formolongi seedlings as materials,second-generation transcriptome sequencing was performed with shoot apical meristem(SAM)samples from the juvenile stage(0-4 months),transition stage(4-6 months)and adult stage(6-24 months)plants.The transcriptome data were assembled and annotated,and 15 172 differentially expressed genes were identified.Additionally,key candidate regulatory pathways involved in the transition from the juvenile stage to the adult stage of L.×formolongi,e.g.,carbohydrate metabolism and regulation of post-embryonic development,were identified.Real-time fluorogenic quantitative polymerase chain reaction(qRT-PCR)was used to verify the expression patterns of six differentially expressed genes during the transition from the juvenile stage to the adult stage.The results showed that the expression trends of the selected genes at different developmental stages were basically consistent with the transcriptome sequencing results,with a coefficient of determination of 0.913 0,demonstrating the reliability of the gene expression data obtained from transcriptome sequencing.In conclusion,based on the use of specific high-quality resources,the generated transcriptome data reflecting the growth process of seedlings lay a foundation for the construction of co-expression networks and core gene mining in the future.关键词
