title: Plant development: light exposure directs meristem fate.
abstract: Leaf initiation was previously thought to be self-regulated and not reliant on environmental cues. However, a recent study has revealed that light redirects meristem fate from maintenance to lateral organ initiation, through the regulation of the plant hormones auxin and cytokinin.
