Phyllobacteriaceae

Phyllobacteriaceae is a family of bacteria belonging to the order Rhizobiales. Members of this family are typically Gram-negative, aerobic, and motile. They are commonly found in soil and plant-associated environments. Phyllobacteriaceae are known for their ability to interact with plants, although the exact nature of these interactions can vary. Some species may be free-living, while others can form symbiotic or associative relationships with plant roots.

The family currently contains several genera, including Phyllobacterium, Shinella, and Pseudaminobacter. The type genus, Phyllobacterium, was first described in 1987 and includes species that have been isolated from various plant tissues and bulk soil. Shinella, established later, contains species known for their metabolic diversity. Pseudaminobacter members are often found in nutrient-poor environments.

Research into Phyllobacteriaceae has explored their roles in biogeochemical cycles, such as nitrogen cycling, and their potential as plant growth-promoting bacteria. Some strains have demonstrated capabilities in nitrogen fixation, phosphate solubilization, and the production of plant hormones. The genetic and physiological characteristics of Phyllobacteriaceae are areas of ongoing investigation, contributing to our understanding of microbial ecology and plant-microbe interactions.
