主要方法:

在洪水和非洪水条件下,微观宇宙试验了四种不同的布拉迪里索比亚菌株.
在盆栽中使用注射的微观宇宙种植阿祖基豆.
使用RFLP分析评估植物生长参数 (发芽长度,发芽干重) 和结节占用率.

主要成果:

起初Bradyrhizobium elkanii (Be31) 占主导地位,但在洪水下其占用率下降.
在洪水条件下,Bradyrhizobium diazoefficiens (Bd110) 的占用率增加.
增加的Bd110占用与增强的射程长度和射程干重相关联.

结论:

土壤洪水改变了布拉迪里索比亚群体结构,使Bd110胜过Be31.
在洪水中提高Bd110的占用率对阿祖基豆的生长产生了积极的影响.
需要推广Bd110和规范Be31的策略,以优化在被洪水淹没的环境中种植阿祖基豆.

Responses to Drought and Flooding

Responses to Drought and Flooding

Water plays a significant role in the life cycle of plants. However, insufficient or excess of water can be detrimental and pose a serious threat to plants.

Adaptations that Reduce Water Loss

Adaptations that Reduce Water Loss

Though evaporation from plant leaves drives transpiration, it also results in loss of water. Because water is critical for photosynthetic reactions and other cellular processes, evolutionary pressures on plants in different environments have driven the acquisition of adaptations that reduce water loss.

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.
