Abstract	The FCA gene, which is a component of the autonomous pathway that regulates flowering time, is an important example of how alternative processing can control plant development. We have previously characterized the FCA homolog, OsFCA, from a japonica-type rice cultivar and demonstrated that the polyadenylation site within intron 3, which can generate non-functional FCA-β, was conserved in rice. In this study, we detected five alternatively processed variants of OsFCA pre-mRNA, four of which were equivalents of FCA-α, -β, -γ, and -δ, in japonica-type Korean rice cultivars. The fifth transcript, referred to as OsFCA-ɛ, was similar to OsFCA-γ, except a part of the OsFCA intron 16 was retained. Unlike the FCA-γ protein, the OsFCA-γ protein contains a glycine-rich region at its N-terminus. We detected the OsFCA transcripts missing the region encoding the glycine-rich domain in the indica-type rice, but not in the japonica-type rice. We also found that the OsFCA-δ and OsFCA-ɛ transcripts were expressed in almost all of the different tissue types examined. Taken together, these results indicate that the alternative processing of the OsFCA transcript is more complex than its Arabidopsis counterpart.
