1 We showed that loss-of-function atmdr1 and atpgp1 mutants display hypersensitivity to far-red, red, and blue-light inhibition of hypocotyl elongation, reduced chlorophyll and anthocyanin accumulation, and abnormal expression of several light-responsive genes, including CAB3, RBCS, CHS, and PORA, under both darkness and far-red light conditions.
