Phototropins 1 and 2: versatile plant blue-light receptors.

Trends in plant science - 1 May 2002

Briggs Winslow R, Christie John M

Abstract excerpt

Blue and ultraviolet-A light regulate a wide range of responses in plants, including phototropism, chloroplast migration and stomatal opening. However, the photoreceptors for these light responses have been identified only recently. The phototropins (phot1 and phot2) represent a new class of receptor kinases that appear to be exclusive to plants. Recent genetic analysis has shown that phot1 and phot2 exhibit...
