The expression of phototropins in Arabidopsis leaves: developmental and light regulation.

Journal of experimental botany - 1 Feb 2012

Łabuz Justyna, Sztatelman Olga, Banaś Agnieszka Katarzyna, Gabryś Halina

Abstract excerpt

Phototropins are blue light receptors, which play different roles during plant development. Two phototropins of Arabidopsis thaliana, phot1 and phot2, have strongly overlapping functions. In seedlings, both photoreceptors are responsible for phototropism. In mature leaves they redundantly regulate leaf shape, stomatal opening, and the accumulation of chloroplasts, whereas phototropin2 alone controls chloroplast...
