| Outline of Final Research Achievements |
Meiosis is a fundamental event for breeding by hybridization. It is known that meiosis-specific DNA/histone modification patterns influence frequencies and genomic positions of meiotic recombination. In this study, we analyzed molecular functions of two rice Argonaute proteins, both of which bind to small RNAs as guides. The results of this study suggest a possibility that either of two AGOs represses a gene required for pollen development during premeiotic and meiotic phases with anther-specific 21nucleotides (nt)-phasiRNAs, and further that another AGO regulates condensation of meiotic chromosomes with meiosis-specific 24nt-phasiRNAs.
