Abstract
The actin-based myosin system is essential for the organization and dynamics of the endomembrane system and transport network in plant cells [1]. Plants harbour two unique myosin groups, class VIII and class XI [2]. There is a little information about myosin in Arabidopsis. Here, we detected 17 myosin genes from the genome of Arabidopsis. Phylogenetic analysis indicated that Arabidopsis myosin genes could be grouped into class VIII and class XI, with three and 11 members, respectively. Analysis of transcription factor binding sites (TFBS) in the promoter region of myosin genes revealed the maximum and minimum number of TFBS in NAC and CSD, respectively. Moreover, variable frequencies of TFSB in myosin genes could indicate that these genes control different developmental stages and are involved in complex regulatory mechanisms. Gene structure analysis showed that the number of exons in myosin genes ranged from 21 to 42 and most of these genes in the same subfamily had similar exon–intron patterns. According to the results of genome distribution, myosin genes were located unevenly on the five A.thahliana chromosomes. Arabidopsis myosins genes were generated from segmental and tandem duplication. Five putative motifs in Arabidopsis myosins were identified using the Pfam and SMART database. Overall, these data provide significant understandings into the evolutionary and functional characterization of Arabidopsis myosin genes that could transfer to the identification and application of homologous myosins of other species.
