bacterial microbiome of Senecio glaucus L.

As more evidence has emerged demonstrating the relevance of plant-associated bacteria for plant growth and productivity, it is believed that interactions between bacteria and alien plants may play a role in plant invasions. Endophytic bacteria have been shown to have a significant impact on the growth and fitness of agriculturally important plants in several studies. However, little information on the composition, variety, and interaction of endophytic bacterial communities in plants contending for survival in Egypt's severe settings, such as the Eastern Desert and the Mediterranean coast, is accessible to our knowledge. However, little is known about the diversity of bacterial communities associated with invasive plants. This research, which exposes the structure of bacterial communities and their possible functions in invasive various portions of Senecio glaucus plants, is the first step in determining the significance of plant bacteria interactions in the Egyptian species invasion, growing in various severe conditions.

随着越来越多证据表明植物相关细菌与植物生长及生产力密切相关，学界普遍认为细菌与外来植物的互作可能在植物入侵过程中发挥作用。多项研究已证实，内生细菌（endophytic bacteria）对多种具有农业重要性的植物的生长与适合度具有显著影响。然而据我们所知，针对在埃及严苛生境（如东部沙漠与地中海沿岸）中生存竞争的植物，其体内内生细菌群落的组成、多样性及互作机制的相关研究信息仍极为匮乏；此外，学界对入侵植物相关细菌群落的多样性也了解有限。本研究针对生长于多种严苛环境中的入侵植物蓝舌千里光（Senecio glaucus），揭示了其不同组织部位的细菌群落结构及其潜在功能，这是探究植物-细菌互作在埃及入侵物种入侵过程中重要性的首项基础性研究工作。
