The evolution of chemosensory receptors in primates

我们从灵长类基因组数据中鉴定了整个嗅觉受体（OR）基因组。此外，我们确定了高通量测序仪从灵长类动物的代表外显子序列。通过对这些数据的比较分析，我们发现链鼻猴和单鼻猴鼻的形态差异对OR基因进化的影响要大于其昼夜生态差异对OR基因进化的影响。这一结果表明，链霉菌在很大程度上依赖于嗅觉。

We identified the entire olfactory receptor (OR) gene sets from primate genome data. Further, we determined the exome sequences from representatives of primates by high-throughput sequencer. From the comparative analyses using these data, we found that the morphological difference of nose between Strepsirrhine and Haplorhine more strongly affected the evolution of OR genes than the ecological difference between diurnal and nocturnal in primates. This result suggested that Strepsirrhine largely depend on olfaction.
