Plant-microbes association: Psychrophilic and psychrotrophic microorganisms associated with plants and their potential environmental services

The association or interaction of species is a phenomenon that occurs in all species on the planet, from bacteria interacting with higher organisms to humans interacting with microbes. There is also interaction with various microorganisms in the plant kingdom. This diversity of plant-microorganism interactions has been widely reported and researched; such interactions could have a substantial impact on the plant. Positive interactions between plants and microorganisms benefit both species; for example, microorganisms obtain a niche for growth as well as prefabricated nutrients to maintain their metabolism. On the other hand, resistance to biotic and abiotic factors improves. Furthermore, bacterial metabolites allow for the plant's efficient development and growth. Plants that grow and develop in low-temperature environments must overcome several challenges, and microorganisms play an important role in this process. Researchers are interested in microorganisms associated with plants that live in cold environments because they have interesting properties. As a result, this chapter aims to understand the potential applications and environmental services of cryotolerant microorganisms associated with cold-adapted plants.
