Regulation of DELLA rice protein interactors and their influence on plant development

Abstract

"DELLA proteins play a pivotal role as key repressors in the gibberellin (GA) signalling pathway. The GA signal perception by the receptor GID1 initiates the formation of the GA-GID1-DELLA complex, leading to DELLA polyubiquitination and subsequent degradation. In the absence of GA, DELLA proteins exert their inhibitory effect on GA-mediated plant growth. Beyond their direct involvement in GA signalling, DELLA proteins act as central players in cellular responses, serving as transcriptional hubs through interactions with transcription factors and transcriptional regulators."
