Three major clusters of numt sequences ( cyt b numt、 ATP8+ATP6 numt and ND4+ tRNA-His+ tRNA-Ser numt) were particularity amplified and sequenced from 10 species within Galliformes and A.galericalata. Comparison numts sequences with homologous mitochondrial partial genes get the different evolutionary characteristics and evolutionary speed compared to mtDNA, then examine the age of insertion of numts using the sequence divergence of numt from the mtDNA. Finally, joined Coturnix japonica、 Coturnix chinensis、 Lophura leucomelana、 Lophura swinhoii and A.albifrons mitochondrial sequences in GenBank, we study the importance function to phylogenetic research of mitochondrial genes and homologous numts.The evolutionary rate of Numts is lower than their authentic sequences of mtDNA, cyt b and ND4 gene evolve faster than homologous numts 2.5 times; ATP8+ATP6 gene evolve faster than numts 18.9 times in Galliformes. Numts show less codon position bias and transition bias under not phylogenetic pressure.

mitochondrial dnais the only inheritant substance except for the nuclear dna in a euˉkaryon cell,which is related to the oxidative phosphorylation of a cell.mitochondrial dna is the important target of carcinogens and is vulnerable because of its structure and function.the mutation of mtdna could reduce the nomal respitation and release large quantities of ros,whichincrease the danger of cancer happening.so,mtdna has been thought to be involved in carcinogenesis and recently more and more studies in this aspect have comeout.in this paˉper,we review the researches for relationship among mtdna mutation and tumors in digestion system,woman system,head and neck,urinary systemand blood system.

线粒体dna（mitochondrial dna，mt dna）是真核细胞中唯一存在的独立于核dna之外的遗传物质，与细胞的氧化磷酸化功能密切相关。mtdna自身的结构和功能特点决定了它是致癌物作用的重要靶点，易受致癌因素的损伤而发生突变。mtdna的突变可削弱正常的呼吸功能，释放高水平的活性氧，进而增加肿瘤发生的危险性，所以mtdna被认为与肿瘤发生有密切关系。近年来，这方面的研究越来越多，本文现就mtdna突变与消化系统肿瘤、妇科肿瘤、头颈部肿瘤、泌尿系统肿瘤等实体瘤以及血液系统恶性肿瘤之间的关系作一简单的综述。

To obtain more information of magnesium homeostasis in mitochondria, mTn-lacZ/LEU2 transposon library was transformed into mrs2 deletion mutant to screen for suppressor genes of MRS2. YMR166C, a member of mitochondrial carrier family, was identified as a suppressor gene of MRS2. Deletion of YMR166C gene can rescue the defects of mrs2 deletion mutant such as the decrease in mitochondrial magnesium concentration, Group II RNA splicing defect and growth defect on nonfermentable carbon source. For the first time we demonstrated YMR166C is involved in mitochondrial magnesium homeostasis.
