About this Research Topic
As sessile organisms, plants have evolved developmental plasticity to cope with both abiotic and biotic stresses. Interactions between plants and microbes, especially endophytic bacteria, are crucial for plant adaptation to adverse environmental conditions. Endophytic bacteria can enhance the growth and development of host plants by secreting iron carriers, for example, to improve nutrient uptake. Endophytic bacteria also help host plants to develop resistance to pathogens through the secretion of elicitors. In addition, there are corresponding endophytic bacteria resistant to abiotic stresses, such as drought-resistant, cold-resistant, and salt-and alkali-resistant species that help host plants grow in unfavorable environments. After the isolated endophytic bacteria were re-inoculated into the plants, the fitness of the plants under unfavorable conditions was significantly improved.
With the advent of new research methods in recent decades, significant advances have been made in the endophytic bacteria interactions with plants. However, studies on the role of endophytic bacteria in host plants under stress conditions are still limited. Therefore, the goal of this Research Topic is to present new research results in the discovery of unique and valuable endophyte resources and to unveil the complex signaling networks in the interactions between endophytic bacteria and host under stress conditions using molecular, biochemical and physiological methods and omics strategies. We welcome submissions of original research papers, reviews, and methods, including (but not limited to) research on the following sub-themes:
1. Beneficial endophytic-bacteria resources for plant stress resistance.
2. Endophytic bacteria-mediated abiotic or biotic responses in plants.
3. Molecular, biochemical and physiological networks in the interactions between endophytic bacteria and host.
4. Key players (chemical or biological) in the interactions between endophytic bacteria and hosts facing adverse environments.
5. Insights into the interactions between endophytic bacteria and host under stressful environments by the omics strategies.
6. Management of the interactions between endophytic bacteria and host plants under stress conditions.
