在人类中,味觉基因负责感知至少5种不同的味道。人类味觉基因的进化机制需要探索。我们编制了69个人类味觉相关基因的清单,并将它们分为7个功能组。我们基于8种脊椎动物对这些味觉基因进行了比较基因组和进化分析。我们发现,相对于其他人类味觉基因组,人类TAS2R基因具有更高比例的串联重复,这表明串联复制对人类TAS2R基因家族的扩大起到了重要作用。人类TAS2R基因在外群物种中具有较少的共线基因,进化速度较快,这表明人类TAS2R基因经历了更多的基因重位。此外,人类TAS2R基因往往比其他基因处于更宽松的净化选择之下。我们的研究为人类口味基因之间不同和不同的进化模式提供了新的见解。
In humans, taste genes are responsible for perceiving at least 5 different taste qualities. Human taste genes’ evolutionary mechanisms need to be explored. We compiled a list of 69 human taste-related genes and divided them into 7 functional groups. We carried out comparative genomic and evolutionary analyses for these taste genes based on 8 vertebrate species. We found that relative to other groups of human taste genes, human TAS2R genes have a higher proportion of tandem duplicates, suggesting that tandem duplications have contributed significantly to the expansion of the human TAS2R gene family. Human TAS2R genes tend to have fewer collinear genes in outgroup species and evolve faster, suggesting that human TAS2R genes have experienced more gene relocations. Moreover, human TAS2R genes tend to be under more relaxed purifying selection than other genes. Our study sheds new insights into diverse and contrasting evolutionary patterns among human taste genes.
