| タイトル | Genome-Wide Identification and Characterization of the ALOG Domain Genes in Rice. | |

Abstract: The ALOG domain genes, named after the <i>Arabidopsis</i> LSH1 and <i>Oryza</i> G1 (ALOG) proteins, have frequently been reported as key developmental regulators in rice and <i>Arabidopsis</i>. However, the investigation of the ALOG gene family is limited. Here, we conducted a genome-wide investigation of the ALOG gene family in rice and six other species. In total, eighty-four ALOG domain genes were identified from the seven species, of which fourteen ALOG domain genes (<i>OsG1</i>/<i>G1Ls</i>) were identified in the rice genome. The fourteen <i>OsG1</i>/<i>G1Ls</i> were unevenly distributed on eight chromosomes, and we found that eight segmental duplications contributed to the expansion of <i>OsG1</i>/<i>G1Ls</i> in the rice genome. The eighty-four ALOG family genes from seven species were classified into six clusters, and the ALOG domain-defined motifs 1, 2, and 3 were highly conserved across species according to the phylogenetic and structural analysis. However, the newly identified motifs 4 and 5 were only present in monocots, indicating a specified function in monocots. Moreover, <i>OsG1</i>/<i>G1Ls</i> exhibited tissue-specific expression patterns. Coexpression analysis suggested that <i>OsG1</i> integrates <i>OsMADS50</i> and the downstream MADS-box genes, such as <i>OsMADS1</i>, to regulate the development of rice inflorescence; <i>OsG1L7</i> potentially associates with <i>OsMADS22</i> and <i>OsMADS55</i> to regulate stem elongation. In addition, comparative expression analysis revealed the conserved biological functions of ALOG family genes among rice, maize, and <i>Arabidopsis</i>. These results have shed light on the functional study of ALOG family genes in rice and other plants. |
