Assessing the conservation impact of Chinese indigenous chicken populations between ex-situ and in-situ using genome-wide SNPs

Journal of Integrative Agriculture 2024年第3期23卷 975-987页

作者： Wenting Li Chaoqun Gao zhao cai Sensen Yan Yanru Lei Mengya Wei Guirong Sun Yadong Tian Kejun Wang Xiangtao Kang College of Animal Science and Technology Henan Agricultural UniversityZhengzhou 450002China The Shennong Laboratory Zhengzhou 450002China

Conservation programs require rigorous evaluation to ensure the preservation of genetic diversity and viability of conservation populations. In this study, we conducted a comparative analysis of two indigenous Chinese chicken breeds, Gushi and Xichuan black-bone, using whole-genome SNPs to understand their genetic diversity, track changes over time and population structure. The breeds were divided into five conservation populations(GS1, 2010, ex-situ;GS2, 2019, ex-situ;GS3, 2019, in-situ;XB1, 2010, in-situ;and XB2, 2019, in-situ) based on conservation methods and generations. The genetic diversity indices of three conservation populations of Gushi chicken showed consistent trends, with the GS3 population under in-situ strategy having the highest diversity and GS2 under ex-situ strategy having the lowest. The degree of inbreeding of GS2 was higher than that of GS1 and GS3. Conserved populations of Xichuan black-bone chicken showed no obvious changes in genetic diversity between XB1 and XB2. In terms of population structure, the GS3 population were stratified relative to GS1 and GS2. According to the conservation priority, GS3 had the highest contribution to the total gene and allelic diversity in GS breed, whereas the contribution of XB1 and XB2 were similar. We also observed that the genetic diversity of GS2 was lower than GS3, which were from the same generation but under different conservation programs(in-situ and ex-situ). While XB1 and XB2 had similar levels of genetic diversity. Overall, our findings suggested that the conservation programs performed in ex-situ could slow down the occurrence of inbreeding events, but could not entirely prevent the loss of genetic diversity when the conserved population size was small, while in-situ conservation populations with large population size could maintain a relative high level of genetic diversity.

民初一些知识分子以报刊为阵地大声疾呼并努力诠释“天下兴亡匹夫有责”。他们赋予此一流行话语以时代新义,其中“天下”与“国家”由异趋同聚合为近代共和国,而“匹夫”则由传统臣民一跃而为近代国民。“天下”与“匹夫”的关系遂转变为国家与国民的新关系。而近代语境下的“匹夫有责”的“责”则凸显为自觉弘扬中华民族传统优秀道义精神,视其为天赋人权精神中应有之义,具体外现为职责、责任、良心与诚信等道德素养,蕴含着浓郁的政治文化与社会文化等价值诉求。这从一个侧面透露出“天下兴亡匹夫有责”渐成中国近代爱国主义的代名词。

Fucoxanthin promotes the chain lengthening reaction of polyunsaturated fatty acids in vivo by enhancing FADS2 enzyme activity

引用

Food Science and Human Wellness 2024年

作者： Xiao-Yue Li Tian-Xin Yang Ying-cai zhao Cheng-Cheng Wang Chang-Hu Xue Teruyoshi Yanagita Yu-Ming Wang Tian-Tian Zhang SKL of Marine Food Processing & Safety Control， College of Food Science and Engineering， Ocean University of China Laboratory of Nutrition Biochemistry， Department of Applied Biochemistry and Food Science， Saga University

Alpha-linolenic acid (ALA) is capable of synthesizing EPA and DHA in vivo， but the conversion rate is hard to meet the body's need for rapid DHA supplementation. Studies have shown that fucoxanthin can increase DHA content in the liver of mice， but the mechanism is not clear. Moreover， the effect of fucoxanthin and its metabolite fucoxanthinol on the chain lengthening reaction of n-6 polyunsaturated fatty acids (PUFAs) is little studied. In this study， the effects of fucoxanthin and fucoxanthinol on the chain elongation of n-3 and n-6 series PUFAs were investigated in mice. Results showed that fucoxanthin and fucoxanthinol significantly increased the conversion of n-3 series ALA to DHA and n-6 series LA to AA in the serum， liver， small intestine， and heart of mice. In addition， fucoxanthin accelerated the rate of DHA supplementation by ALA in the brain. Further mechanistic studies revealed that the role of fucoxanthin in promoting PUFAs conversion was not regulated at transcriptional level， but by increasing the activity of fatty acid desaturase 2 (FADS2)， a key enzyme of chain elongation reaction of n-3 and n-6 PUFAs. This study fundamentally provided theoretical bases for a new strategy of dietary supplementation of n-3 and n-6 PUFAs.

假设瞬态荷载沿隧道方向按指数衰减,建立非饱和介质中圆柱形衬砌隧道受到内源爆炸荷载作用时衬砌隧道及周围非饱和介质计算模型。基于多孔介质混合物理论和连续介质力学理论,推导爆炸荷载作用下衬砌结构及周围非饱和土的控制方程,运用Laplace及Fourier变换求得隧道衬砌及周围土体在频域-波域内的解析解答,研究内源爆炸作用下饱和度对衬砌结构动力响应的影响。计算结果表明:饱和度对衬砌内表面径向位移影响较大,在轴向上,随着饱和度由0.15增至0.98,爆源处的径向位移值升高约28%;衬砌内表面径向应力随时间变化受饱和度的影响不明显;衬砌内表面环向应力幅值随饱和度的增大而增大,且达到幅值所用的时间逐渐延迟。在轴向上,随着饱和度由0.15增至0.98,爆源处环向应力升高约29%。
