Abstract The photoperiodic sensitivity 5 (se5) mutant of rice, a short-day plant, has a
very early flowering phenotype and is completely deficient in photoperiodic
response. We have cloned the SE5 gene by candidate cloning and demonstrated that
it encodes a putative heme oxygenase. Lack of responses of coleoptile elongation
by light pulses and photoreversible phytochromes in crude extracts of se5
indicate that SE5 may function in phytochrome chromophore biosynthesis. Ectopic
expression of SE5 cDNA by the CaMV 35S promoter restored the photoperiodic
response in the se5 mutant. Our results indicate that phytochromes confer the
photoperiodic control of flowering in rice. Comparison of se5 with hy1, a
counterpart mutant of Arabidopsis, suggests distinct roles of phytochromes in
the photoperiodic control of flowering in these two species.
