植物生物学植物生物学
微生物组研究的研究.
遗传学遗传学是一个

背景情况:

根微生物组组成影响植物生长,并与宿主基因组变异有关.
目前尚不清楚植物是否积极操纵它们的根微生物组以适应环境,或者变异是被动发生的.

研究的目的:

为了调查theosinte基因组,环境因素和根微生物组组成之间的关系.
为了确定根微生物组的变异是否是一种有针对性的适应或是其他特征的被动后果.

主要方法:

泰奥辛特种子是在墨西哥原生范围收集的.
在一个共同的花园实验中,Teosinte连接和两条现代玉米线生长.
根微生物组使用细菌和真菌元编码进行了分析.

主要成果:

在theosinte加入和现代玉米系之间观察到根微生物组的显著变化.
素基因组变异,祖先环境 (温度/海拔) 和根微生物组组成是相关的.
特定的微生物群体表现出随着温度/海拔高度的丰度变化,耐寒细菌在高海拔的高温中增加.

结论:

The Roles of Bacteria and Fungi in Plant Nutrition

The Roles of Bacteria and Fungi in Plant Nutrition

Plants have the impressive ability to create their own food through photosynthesis. However, plants often require assistance from organisms in the soil to acquire the nutrients they need to function correctly. Both bacteria and fungi have evolved symbiotic relationships with plants that help the species to thrive in a wide variety of environments.

Anatomy of the Intestines

Anatomy of the Intestines

Although digestion of proteins, carbohydrates, and lipids may begin in the stomach, it is completed in the intestine. The absorption of nutrients, water, and electrolytes from food and drink also occurs in the intestine. The intestines can be divided into two structurally distinct organs—the small and large intestines.
Small Intestines
The small intestine is an ~7 meter-long tube with an inner diameter of just 2.5 cm. Since most nutrients are absorbed here, the inner lining of the...
