Abstract:
In several plant species, inflorescence formation is accompanied by stem elongation. Both processes are accelerated in rice upon perception of shortening days. Here, we show that PREMATURE INTERNODE ELONGATION 1 (PINE1), encoding a rice zinc-finger transcription factor, reduces the sensitivity of the stem to gibberellin (GA). The florigens reduce PINE1 expression to increase stem responsiveness to GA and promote flowering. These data indicate the existence of a regulatory network coordinating flowering and GA-dependent growth.

Transcription Elongation Factors
The transcription elongation is regulated via pausing of RNA polymerase on several occasions during transcription. In bacteria, these halts are necessary because the transcription of DNA into mRNA is coupled to the translation of that mRNA...
