#Unit 6. System Physiology – Plant

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

Red and far-red lights are perceived by plants through various photoreceptors including phytochromes. The red/far-red reversibility of seed germination was due to the-

a) photoreversibility of phytochrome

b) presence of red and far-red light at different fluence rate

c) Conversion of Pr to Pfr form through the effect of red light

d) equal proportion of red and far red light at same fluence rate
