摘要

MADS-box transcription factors (MADS-box TFs) are central regulators integrating environmental cues with developmental and stress-adaptive mechanisms in plants. MADS-box TFs typically regulate target gene expression by binding to CArG-box [CC(A/T)GG] motifs, as well as through non-canonical mechanisms. One stress response modulated by MADS-box TFs is to drought. Here, a network of morphological modifications, physiological homeostasis, and transcriptome-wide reprogramming is altered by MADS-box TFs. MADS-box TFs balances organ development with stress acclimation and act as hubs to modulate hormone biosynthesis and signaling pathways regarding drought tolerance through manipulating gene expression. MADS-box TF activity is typically modified by post-translational events, particularly phosphorylation and dephosphorylation, to fine-tune plant adaptation to desiccation conditions. Evolutionarily, the functional conservation and divergence of MADS-box TFs dictate the progression of drought tolerance in plants. In addition, MADS-box TFs function in a spatiotemporally dynamic manner, critically modulating plant architecture formation and drought adaptation. In this review, we summarize the diverse regulatory networks orchestrated by MADS-box TFs that offer promising targets for designing crop plants with improved organ development and drought stress resilience.
