A herbicides dichlorophenyldimethylurea (DCMU) is known as diuron an inhibitor of photosynthetic electron transport. Which one of the following option would be correct about diuron?
a.) Blocks electron flow at the plastoquinone acceptors of PSII by competing for the binding site of plastoquinone
b.) causes a partial inhibition of stomatal closing
c.) accepts electrons from the early acceptors of PSI such as A0 and then reacts with oxygen to form superoxide, O2 –
d.) causes a partial inhibition of light-stimulated stomatal opening

Multiple factors regulate flowering in Arabidopsis. FT mRNA is expressed in companion cells of the leaf vein in response to multiple signals, including day length, light quality, and temperature. FT moves in the phloem from leaves to the apical meristem. FT is unloaded from the phloem in the meristem and interacts with FD.
FT-FD complex activates multiple genes. Which of the following combination is correct?(SS)
