Structural variation in the IAMH2 3′ UTR underlies hypocotyl elongation during light adaptation in Arabidopsis thaliana
SUMMARY Plant hypocotyls are central to seedling establishment in variable light environments. Although core photoreceptor pathways regulating hypocotyl elongation are well defined, the molecular basis of natural variation in this trait—particularly through posttranscriptional regulation—remains poorly understood. Here...
