脸部形态是人类重要的生物特征之一,了解脸部形态特征的遗传基础在群体遗传学、发育生物学和法庭科学中具有重要意义。本研究针对中国汉族成年男性人群1177名个体,在高分辨率三维人脸图像的17个脸部特征点中提取出136组欧几里德距离(Euc... 脸部形态是人类重要的生物特征之一,了解脸部形态特征的遗传基础在群体遗传学、发育生物学和法庭科学中具有重要意义。本研究针对中国汉族成年男性人群1177名个体,在高分辨率三维人脸图像的17个脸部特征点中提取出136组欧几里德距离(Euclidean distance)表型。结合3×低深度测序数据,用线性回归分析了125个已报道的与脸部形态显著相关的SNP位点和136组脸部表型之间的相关性。结果表明,在经过多重校正后,来自10个不同基因区域的12个SNP位点与一个或多个脸部特征显著相关(显著性阈值P<1.35×10^–3),解释了年龄和BMI指数校正后3.89%脸部表型差异。相关SNP位点包括TEX41 rs17479393,PAX3 rs974448、RAB7A/ACAD9 rs2977562、DCHS2 rs9995821、DCHS2 rs2045323、C5orf50 rs6555969、SUPT3H/RUNX2 rs1852985、MSRA rs11782517、EYA1 rs10504499、GSC rs2224309、DICER1 rs7161418和DHX35 rs2206437。本研究结果对揭示中国汉族人群脸部形态的遗传机制和脸部特征的遗传推断提供了参考数据。 展开更多

[Objectives]To explore pathways and countermeasures for transforming farmers livelihoods in the way of reducing their dependence on land while promoting sustainable development and alleviating ecological degradation.[Methods]A combination of field research,literature review,and policy analysis was employed to identify key factors affecting farmers livelihoods and potential strategies for transformation.[Results]The study found that developing ecological agriculture and modern agriculture,promoting agricultural transformation and upgrading,cultivating alternative industries,strengthening ecological engineering construction,and establishing diversified ecological compensation methods and supporting policies are effective strategies for transforming farmers livelihoods.[Conclusions]Implementing these strategies can help alleviate the contradiction between ecological protection and farmers livelihood development,promoting coordinated development of both.This approach not only benefits farmers but also contributes to sustainable environmental management and biodiversity conservation. 展开更多
