A particular interest in primate genetics was fueled by the release of the complete human genome sequence drafts reported in 2001 by the IHGSC and Celera Genomics. Postgenomic comparative analyses based on the complete genome sequence of the mouse started focusing on functional, evolutionary and diversity aspects of human DNA. By analyzing molecular character states in the representatives of the major primate groups one is able to reconstruct the processes that shape genomes on the lineage to humans after the mouse-human divergence. Consequently, several primate genome sequences are about to be generated during Whole Genome Shotgun (WGS) sequencing projects and are already available for two representatives of the Old World monkeys and hominoids (rhesus monkey, chimpanzee). Comparative data restricted to functional genome parts of a meaningful primate sample (ENCODE project) are underway. These data will yield a definite phylogenetic framework linking the mouse, primate related eutherians and the major primate groups, which is indispensable for any analysis of character evolution. Concerning the functional site comparative genetic research in primates on molecular phenomena that control the spatiotemporal profile of the cellular RNA and protein composition will contribute to our understanding of genotype-phenotype correlations and the emergence of human specific traits.
2001年国际人类基因组测序协作组(IHGSC)和塞雷拉基因组公司公布了人类基因组序列草图,这激发了人们对灵长类遗传学的特别兴趣。基于小鼠全基因组序列的后基因组比较分析开始聚焦于人类DNA的功能、进化和多样性方面。通过分析主要灵长类群体代表的分子特征状态,人们能够重建在小鼠与人类分化后人类谱系上塑造基因组的过程。因此,在全基因组鸟枪法(WGS)测序项目中即将产生多个灵长类基因组序列,并且旧世界猴和类人猿的两个代表(恒河猴、黑猩猩)的基因组序列已经可用。限于有意义的灵长类样本功能基因组部分的比较数据(ENCODE项目)正在进行中。这些数据将产生一个明确的系统发育框架,将小鼠、与灵长类相关的真兽类和主要灵长类群体联系起来,这对于任何性状进化分析都是不可或缺的。关于灵长类动物中控制细胞RNA和蛋白质组成时空特征的分子现象的功能位点比较遗传研究,将有助于我们理解基因型与表型的相关性以及人类特有性状的出现。
