Our results provide further insight into the regulation of DELLA proteins in Arabidopsis . We clarified that phosphorylation modification of the six conserved sites is important for RGA functions and stability. The DELLA proteins, important plant growth and development repressors mediate the gibberellin (GA) signaling pathway. Although these proteins(More)
Fackel (FK) is involved in the flowering of Arabidopsis mainly via the gibberellin pathway and vernalization pathway. This new function of FK is partially dependent on the FLOWERING LOCUS C ( FLC ). A common transitional process from vegetative stage to reproductive stage exists in higher plants during their life cycle. The initiation of flower bud(More)
