Abstract excerpt
Leaf width is an important component of plant architecture that strongly affects light capture during photosynthesis and thus grain yield, particularly under dense planting conditions. However, the genetic and molecular mechanisms regulating leaf width in wheat (Triticum aestivum L.) remain unclear. Here, we identified the narrow-leaf mutant nl1 with fewer small veins than the wild-type and isolated the...
