概括

盐度压力通过改变肠道细菌和神经递质影响红耳滑鼠的繁殖,通过肠-大脑-生殖腺轴影响精子干细胞功能.

科学领域:

*生态毒理学和生殖生物学.
* 侵入性物种适应和保护遗传学.

背景情况:

*红耳滑鼠 (Trachemys scripta elegans) 是入侵性的,可以适应盐环境,对本地生物多样性构成威胁.
*精子干细胞 (SSC) 对于男性生育至关重要,并由肠-大脑-阴茎轴调节,但盐度对SSC的影响尚不清楚.

研究的目的:

* 调查盐度压力如何影响T. s. elegans的肠道微生物群组成.
* 确定盐度诱导的肠道微生物群变化是否调节SSC通过肠-大脑-生殖腺轴的自我更新和分化.

主要方法:

* T. s. elegans 在六个月内暴露在三种盐度水平 (0‰,5‰,10‰) 上.
*分析SSC自我更新和介质启动基因的mRNA表达.
*肠道微生物群的组成和代谢物分析,重点关注神经递质的关联.

主要成果:

*增加的盐度显著降低了SSC自我更新和介质启动基因的表达.
*有害细菌 (菌,菌) 随盐度增加而增加,而有益细菌水平发生变化,影响GABA水平.
*盐度通过改变肠道微生物群和代谢物改变了神经递质分泌和生殖激素合成.

结论:

*盐度压力对T. s. elegans的SSC功能和生殖能力产生负面影响.
*肠-大脑-腺轴通过肠道微生物群和代谢物变化调解盐度对生殖的影响.
* 结果提供了对T. s. elegans在水中的适应机制的见解.

关键词:

Responses to Salt Stress

Responses to Salt Stress

Salt stress—which can be triggered by high salt concentrations in a plant’s environment—can significantly affect plant growth and crop production by influencing photosynthesis and the absorption of water and nutrients.
