Natural variations at the Stay-Green gene promoter control lifespan and yield in rice cultivars

D. Shin, S. Lee, et al.

This study by Dongjin Shin and colleagues unveils the genetic factors behind the distinct life cycle and senescence patterns in rice subspecies *indica* and *japonica*. Key promoter variations in the Stay-Green (OsSGR) gene were linked to earlier senescence in *indica*. Introducing *japonica* alleles into *indica* cultivars not only delayed senescence but also boosted grain yield and photosynthetic efficiency, highlighting promising avenues for enhancing rice productivity.
