GmBBX13 and GmBBX4a/b antagonistically regulate GmCML19 transcription to fine-tune leaf senescence in soybean.
Leaf senescence is a critical developmental process that fundamentally determines crop yield and quality. Here, we report that the B-box CONTAINING PROTEIN 13 (GmBBX13) negatively regulates leaf senescence in soybean. Overexpression of GmBBX13 in soybean significantly delays leaf senescence onset. GmBBX13 physically in...
