The conversion of Pr to Pfr by red light, both phyA and phyB move from the cytosol into the nucleus in a light-dependent fashion.

a) Both have nuclear localization signal (NLS) sequences

b) PRD domain of phyB can potentially serve as an NLS, but it is apparently masked in the Pr form

c) phyA dependent on other proteins, such as FAR-RED ELONGATED HYPOCOTYL1 (FHY1) facilitating phyA’s transport it into the nucleus

d) Both phyA and phyB have PRD domain serve as an NLS and responsible for import into the nucleus only in pfr form may expose the functional NLS of the PRD domain

Which of the following factors is involved for transporting phyA and B into the nucleus?
