摘　　要：采用HMMER与BLAST相结合的方法确定拟南芥,水稻和杨树三种模式植物全基因组JMJC蛋白基因个数分别为21,20,24,并对其染色体定位,基因结构,保守功能域进行了系统分析,在系统进化分析基础上,将JMJC家族分为11个亚家族,内含子外显子结构分析与MPSS表达模式分析结果也进一步支持了进化关系研究.本研究有助于揭示植物JMJC基因家族的进化历史,为后续JMJ基因家族的功能提供线索,为进一步研究植物JMJC基因家族提供理论基础。In this study ,bioinformatics analysis methods including HMMER and BLAST identified 21,20,24 JMJC domain contained genes respectively in Arabidopsis, rice and poplar. A comprehensive overview of this gene family is presented, including the gene structure, phylogeny, chromosome distribution, conserved motifs . The plant JMJC gene family are organized into 11 subfamilies based on phy- logenetic relationship. In addition, the conservation of intron/exon structuaral patterns and MPSS pattern analysis further support the ev- olutionary relationships among these proteins. Our results provide clues for study of gene family evolution, and a solid base for future functional studies of the JMJC gene family in plants.
