| Title | Evolutionary Analysis of <i>GH3</i> Genes in Six <i>Oryza</i> Species/Subspecies and Their Expression under Salinity Stress in <i>Oryza sativa</i> ssp. <i>japonica</i>. | |

Abstract: Glycoside Hydrolase 3 (<i>GH3</i>), a member of the Auxin-responsive gene family, is involved in plant growth, the plant developmental process, and various stress responses. The <i>GH3</i> gene family has been well-studied in <i>Arabidopsis thaliana</i> and <i>Zea mays</i>. However, the evolution of the <i>GH3</i> gene family in <i>Oryza</i> species remains unknown and the function of the <i>GH3</i> gene family in <i>Oryza sativa</i> is not well-documented. Here, a systematic analysis was performed in six <i>Oryza</i> species/subspecies, including four wild rice species and two cultivated rice subspecies. A total of 13, 13, 13, 13, 12, and 12 members were identified in <i>O. sativa</i> ssp. <i>japonica</i>, <i>O. sativa</i> ssp. <i>indica</i>, <i>Oryza rufipogon</i>, <i>Oryza nivara</i>, <i>Oryza punctata</i>, and <i>Oryza glumaepatula</i>, respectively. Gene duplication events, structural features, conserved motifs, a phylogenetic analysis, chromosome locations, and Ka/Ks ratios of this important family were found to be strictly conservative across these six <i>Oryza</i> species/subspecies, suggesting that the expansion of the <i>GH3</i> gene family in <i>Oryza</i> species might be attributed to duplication events, and this expansion could occur in the common ancestor of <i>Oryza</i> species, even in common ancestor of rice tribe (<i>Oryzeae</i>) (23.07~31.01 Mya). The RNA-seq results of different tissues displayed that <i>OsGH3</i> genes had significantly different expression profiles. Remarkably, the qRT-PCR result after NaCl treatment indicated that the majority of <i>OsGH3</i> genes play important roles in salinity stress, especially <i>OsGH3-2</i> and <i>OsGH3-8</i>. This study provides important insights into the evolution of the <i>GH3</i> gene family in <i>Oryza</i> species and will assist with further investigation of <i>OsGH3</i> genes' functions under salinity stress. |
