Abstract

Cellulosimicrobium sp. JZ28, a root endophytic bacterium from the desert plant Panicum turgidum, was previously identified as a plant growth-promoting bacterium. The genome of JZ28 consists of a 4378,193 bp circular chromosome and contains 3930 CDSs with an average GC content of 74.5%. Whole-genome sequencing analysis revealed that JZ28 was closely related to C. aquatile 3 bp. The genome harbors genes responsible for protection against oxidative, osmotic and salinity stresses, such as the production of osmoprotectants. It also contains genes with a role in the production of volatiles, such as hydrogen sulfide, which promote biotic and abiotic stress tolerance in plants. The presence of three copies of chitinase genes indicates a possible role of JZ28 as biocontrol agent against fungal pathogens, while a number of genes for the degradation of plant biopolymers indicates potential application in industrial processes. Genome sequencing and mining of culture-dependent collections of bacterial endophytes from desert plants provide new opportunities for biotechnological applications.
