Abstract

Abstract: Gibberellins (GAs) are a pervasive group of diterpene phytohormones. They can dominate various aspects of plant development and modulate plant phenotypic plasticity by crosstalking with multiple phytohormones. Studies on GA signaling illustrate that master negative regulator DELLA proteins regulate GAs and nearly all phytohormones' growth responses to sustain plant growth and defense under relentless biotic and abiotic stresses. The molecular mechanism of DELLA proteins in regulating GA‐sensitive growth in an integrated manner with multiple phytohormones became apparent recently. These studies describe the interaction of interaction DELLA proteins with a diverse group of transcriptional regulators and factors as well as nontranscriptional proteins in directing GA‐stimulated plant growth. In this review, we address the extensive recent work to delineate DELLA proteins and their interacting partners and summarize the latest evidence that DELLA proteins have a unique function in suppressing the GA‐related responses to sustain the tension among growth and defense. Core Ideas: This review summarizes the latest progress of GA signaling in plant development. This review highlights the pivotal role of DELLA proteins and their interacting targets in plant major developmental process. This study provides insights into how GA signaling integrates with multiple phytohormones and environmental cues. This study provides mechanistic understanding on how DELLA proteins sustain tension among growth and defense.
