胡萝卜抽薹性相关调控基因的挖掘
Mining of Regulatory Genes Related to Bolting in Carrot
摘要
Abstract
Premature bolting seriously affects the commercial value of carrot taproots and production of overwintering and spring cultivation in China.To study regulatory mechanism and identify functional genes related to bolting traits,we compared the transcriptome data of the wild species'Songzi Wild'with bolting-sensitive and annual habit and the cultivated variety'Amsterdam Forcing'with bolting-tolerant and biennial habit at three growth stages during bolting.A total of 2 320 differentially expressed genes were detected,which were mainly enriched in cellular processes and metabolic processes of biological processes,and the catalytic and binding activity functions in molecular functions.Finally,32 flowering time genes were identified,which mainly involved in the photoperiod,gibberellin,vernalization pathway and flowering integrator factors.Among them,the expression levels of AP1,AP2,AGL19,TPS1,and four SOC1 genes showed significantly higher differences in all three stages between two species.SOC1s(DCAR_209690,DCAR_209695 and DCAR_414778)were specifically expressed in Ws,which provided a scientific basis to research bolting traits and provided theoretical reference for the selection and breeding of carrot varieties with different bolting habits.关键词
