番茄MIKCc型MADS-Box基因保守模式和启动子的信息学分析

In plants, MADS-box genes have been shown to be involved in all aspects of plant development, especially in flower development in angiosperms such as Arabidopsis. To understand the diversity in regulation present in these subfamilies, we investigated 42 MIKCc-type MADS-box genes from the genome of tomato, including 7 genes that have not previously been characterized. Using these sequences, we have performed a comparative analysis of tomato MIKCc-type MADS-box genes, including the description of the protein conserved motif, promoter motif and genome localization of each member. Our results suggest that many genes have diverged in their sequences after duplication and/or speciation. They also suggest that these genes may have evolved through segmental duplication events produced by polyploidy events in the past. Overall, the comparative analysis of the tomato MIKCc-type MADS-box genes will be expected to result in significant progress in investigating the regulation mechanism of MADS-box genes in higher plants.
