Comparative transcriptome analysis of axillary buds in response to the shoot branching regulators gibberellin A3 and 6-benzyladenine in Jatropha curcas.

ABSTRACT: Cytokinin (CK) is the primary hormone that positively regulates axillary bud outgrowth. However, in many woody plants, such as Jatropha curcas, gibberellin (GA) also promotes shoot branching. The molecular mechanisms underlying GA and CK interaction in the regulation of bud outgrowth in Jatropha remain unclear. To determine how young axillary buds respond to GA₃ and 6-benzyladenine (BA), we performed a comparative transcriptome analysis of the young axillary buds of Jatropha seedlings treated with GA₃ or BA. Two hundred and fifty genes were identified to be co-regulated in response to GA₃ or BA. Seven NAC family members were down-regulated after treatment with both GA₃ and BA, whereas these genes were up-regulated after treatment with the shoot b
