Increase in starch concentration by using rice SUB1A-1 transcription factor. (a) Wild-type plants have an intact flowering signaling system through CONSTANS (CO) and FLOWERING LOCUS T (FT). (b) Plants transformed with the ETHYLENE RESPONSE FACTOR gene SUBMERGENCE1A-1 (SUB1A) have a delay in flowering time through the transcriptional inhibition of CO and FT, temporally accumulating starch otherwise used to fuel flowering development [13].
