Three main classes of photoreceptors mediate the effects of UV-A/blue light:

a) the cryptochromes,

b) the phototropins,

c) the phytochrome and

d) the ZEITLUPE (ZTL)

Function of these photoreceptors are-

i) that can promote plant photomorphogenesis

ii) plays roles in day length perception and circadian rhythms

iii) regulate chloroplast movements, and stomatal opening
