This narrative review synthesizes current understanding of leaf senescence in Arabidopsis thaliana and crop plants, covering genetic and molecular regulatory mechanisms identified through forward and reverse genetic approaches. The review highlights that leaf senescence is governed by multi-layered regulation including chromatin, transcriptional, post-transcriptional, translational, and post-translational control.
This narrative review examines the biology of leaf senescence, the final stage of leaf development characterized by a transition from nutrient assimilation to nutrient remobilization. Key regulatory layers include chromatin remodeling, transcriptional regulation by transcription factors, and post-transcriptional, translational, and post-translational control mechanisms. The review notes that strategies based on senescence regulatory mechanisms have been explored to manipulate senescence for higher yield, better quality, or improved horticultural performance. Limitations include incomplete understanding of hormonal crosstalk, the integration of developmental and environmental signals, and the challenge of translating findings from model plants to specific crop species.
