摘要: Plants adapt to adverse environments by integrating growth and development environmentally activated cues. Within the adaptive signaling networks, plant hormones tightly control convergent developmental stress processes coordinate cellular responses external internal conditions. Recent studies have uncovered novel antagonizing roles of gibberellin (GA) abscisic acid (ABA) in plants with environmental signaling. According current concepts, GRAS transcription factors DELLA SCARECROW-LIKE (SCL) types a key role as major regulators pivotal functions modulating GA Significantly, models emphasize function proteins central homeostasis. interact receptor GID1 (GA-INSENSITIVE DWARF1) degradation DELLAs activates GA. Supplementary prevailing view family transcriptional regulation, recent work has suggested that SCL integrate generic into ABA-controlled abiotic tolerance. Here, we review discuss how type influence versatile adaptation hubs ABA triggered pathways.
