Abstract excerpt
Flowering time genes often exhibit pleiotropic effects. In particular, early flowering is frequently associated with reduced grain yield due to a shorter growth period. This trade-off poses a major challenge for developing early-maturing and high-yielding varieties, a key breeding objective in modern maize production. Here, we demonstrate that ZmRap2.7, a well-known flowering repressor in maize, positively...
