GA-GRF module – A key regulator of rice leaf length via spatial cell division control (New Phytol)
Plant Science Research WeeklyLeaf features have undergone significant changes during the course of evolution and domestication owing to ecological adaptations and changes in source-sink dynamics. Therefore, wild relatives of crop plants are important resources for exploring the genetic regulation of leaf features that might not…
