| Abstract: | SINA genes in plants are part of a multigene family with 5 members in Arabidopsis thaliana, 10 members in Populus trichocarpa, 6 members in Oryza sativa, at least 6 members in Zea mays and at least 1 member in Physcomitrella patens. Six members in maize were confirmed by RT-PCR. All SINAs have one RING domain and one SINA domain. These two domains are highly conserved in plants. According to the motif organization and phylogenetic tree, SINA family members were divided into 2 groups. In addition, through semi-quantitative RT-PCR analysis of maize members and Digital Northern analysis of Arabidopsis and rice members, we found that the tissue expression patterns are more diverse in monocot than in Arabidopsis. |
