Project description:The molecular mechanism of seed morphophysiological dormancy of Epimedium pseudowushanense B.L.Guo. remains largely unknown. The endogenous ABA and GA content of E. pseudowushanense seeds at three developmental stages was quantitatively determined. The result showed the levels of ABA in E. pseudowushanense seeds decreased during the seed embryo growing and development, levels of GA3 increased during seed embryo growing, and levels of GA4 increased during seed dormancy releasing and seed sprouting. High-throughput sequencing method was used for reveal the E. pseudowushanense seed transcriptome. The transcriptome data were assembled as 178,613 unigenes and the numbers of differentially expressed unigenes between the seed development stages were compared. By computer analysis of the KEGG reference pathways, twelve candidate genes were likely to be involved in metabolism and signaling of abscisic acid and gibberellins. The expression patterns of these genes were revealed by real-time quantitative RT-PCR. Phylogenetic relationships among the deduced E. pseudowushanense proteins and their homologous in other plant species were analyzed. The results indicate EpNCED1, EpNCED2, EpCYP707A1 and EpCYP707A2 are likely to be involved in ABA biosynthesis and catabolism. EpSnRK2 is likely implicated in ABA signaling during seed dormancy. EpGA3ox is likely to be involved in gibberellin biosynthesis, and EpDELLA1 and EpDELLA2 are likely implicated in GA signaling. This study was the first to provide the E. pseudowushanense seed transcriptome and the key genes involved in metabolism and signaling of abscisic acid and gibberellins, and so it is valuable for studies on seed morphophysiological dormancy mechanism
