Transcriptional responses analysis of the inflorescence meristems in Jatropha curcas following gibberellin treatment

Our results showed that 951 differentially expressed genes (DEGs) were obtained to response to gibberellin treatment. The 6-h time point was an important phase in the response to exogenous gibberellin. Furthermore, the plant endogenous gibberellin, auxin, ethylene, abscisic acid, and brassinolide signaling transduction pathways were repressed after exogenous GA3 treatment. However, the DEGs (JcAHP1, JcHK3, and JcMYC2, JcMYC4) which were respectively associated with cytokinin and jasmonic acid signaling were up-regulation for 24-h time point following GA3 treatment. In addition, the floral meristem determinacy genes (JcLFY and JcSOC1) and floral organ identity genes (JcAP3, JcPI, and JcSEP1-3) were significantly up-regulated, but their negative factor (JcSVP) was down-regulated after GA3 treatment. Overall design: Five different samples after exogenous GA3 treatment.
