A 3-bp deletion of WLS5 gene leads to weak growth and early leaf senescence in rice

Background In rice (Oryza sativa) and other grains, weak growth (dwarfism, short panicle length, and low seed-setting rate) and early senescence lead to reduced yield. The molecular mechanisms behind these processes have been widely studied; however, the complex genetic regulatory networks controlling growth and senescence require further elucidation.
