We report the isolation, sequence, and gene expression patterns of RMD1, a novel member of the STMADS11 subfamily from rice. Northern blot analysis revealed that expression pattern of RMD1 is different from that of other members of STMADS11 subfamily reported so far. All the members of STMADS11 subfamily has been reported that their expression is detected in vegetative tissues, but RMD1 is mainly expressed during flower development and embryogenesis. In situ hybridization analysis revealed that RMD1 expression is localized in developing stamen primordia and outermost cell layer in embryos. Over/ectopic expression of RMD1 in transgenic rice plants induced abnormal reproductive growth similar to transgenic tobacco plants expressing STMADS16. These results are discussed in terms of a possible role for RMD1 in promoting similar molecular function to STMADS11-like proteins although their expression patterns quite differ.
