Abstract excerpt

Chlorophyll content is a pivotal agronomic trait that directly determines photosynthetic efficiency and visual quality in tomato (Solanum lycopersicum). Although positive regulators of chlorophyll biosynthesis have been extensively characterized, the mechanisms of their transcriptional repression remain less understood. Here, we report that the GRAS family transcription factor SlGRAS17 functions as a key negative...
