Turning over a green leaf: integrating light signals towards chloroplast establishment
Abstract Light is indispensable for transitioning from a heterotrophic to a photoautotrophic state. Etiolated seedlings, developed in darkness, are primed for rapid chloroplast development upon light exposure. In this transition, dark-adapted etioplasts differentiate into functional chloroplasts through a tightly regulated process controlled at multiple levels. Light steers gene transcription…
