N2 - During the processes of pollen recognition, pollen-tube guidance, fertilization, and early embryogenesis, a complicated gene network is highly regulated in plants. To visualize the profile of gene expression during these processes, we performed cDNA microarray analysis with RNA isolated from rice pistils at several stages. We identified 32 cDNA clones, in 21 non-redundant groups, with pistil-specific expression patterns. These genes could be clustered into five groups based on expression patterns, and included pathogenesis-related genes, transcription factors, and genes related to pollen germination, pollen tube elongation, and starch degradation. The microarray analysis identified several previously undescribed genes that are expressed in a pistil-specific manner. These results provide new clues to the molecular mechanisms that underlie plant reproduction.
