摘要：

鉴定了覆盖拟南芥、水稻和杨树3种模式植物全基因组的20个拟南芥、18个水稻、22个杨树ACTIN蛋白基因，对其染色体定位、基因结构、基因复制等进行了综合分析.并在系统进化分析基础上，将ACTIN基因家族分为12个亚家族,有助于揭示植物ACTIN基因家族的进化历史，为后续ACTIN基因家族的功能提供线索，对研究植物ACTIN基因家族功能和进化上的多样性提供理论基础.

Abstract:

Actins are structural proteins widely distributed in eukaryotes. In plants, the actin cytoskeleton plays an essential role in many cellular processes including cell division and cytoplasmic streaming. Study of the ACTIN gene family is important for understanding the mechanism of these processes. In this study, bioinformatics analysis identified 20, 18 and 22 ACTIN genes respectively in arabidopsis, rice and poplar. A comprehensive overview of this gene family is presented, including chromosome distribution, gene structure, gene duplication, phylogeny, and conserved motifs. The plant ACTINs are organized into 12 subfamilies based on phylogenetic relationship. These results provide clues for study of gene family evolution, and serve as a solid base for future functional genomic studies of the ACTIN gene families in plants.
