In Arabidopsis thaliana, the transition to flowering involves multiple factors, pathways and meristem identity genes. Following statements regarding to the mechanism and function of meristem identity genes.

 A. FT mRNA is expressed in companion cells of the leaf vein in response to multiple signals, including day length, light quality, and temperature.

 B. The FT–FD complex activates AP1 in the inflorescence meristem and SOC1 in the floral meristem, which triggers LFY gene expression.

 C. LFY and AP1 trigger expression of the floral homeotic genes.

 D. FLC acts as a negative regulator of SOC1 in the meristem and as a negative regulator of FT in the leaves.

 Which of the following is incorrect?

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
