Is pbr1 a light-inducible gene?

To test whether PBR1 is a light-inducible gene, GUS activities were examined in the ProPBR1::GUStransgenic plants. The results showed that PBR1was highly expressed in greening of the transgenic etiolated seedlings in a light-inducible way (Figure 8a).

Does pbr1 selectively control biogenesis of photosynthetic complexes?

Does pbr1 regulate the biosynthesis of YCF1?

Taken together, these results demonstrate that PBR1 regulates the biosynthesis of Ycf1 that may be the possible mediator protein involving biogenesis of NDH, PSI and Cytb6fcomplexes. Figure 6 PBR1knockdown impairs accumulation of the Ycf1 protein in thylakoid membranes and association of the Ycf1transcript with polysomes.
