Bacterial endophytes with capacity to promote plant growth and improve plant tolerance against biotic and abiotic stresses have importance in agricultural practice and phytoremediation. A plant growth-promoting endophyte named Klebsiella sp. LTGPAF-6F, which was isolated from the roots of the desert plant Alhagi sparsifolia in north-west China, exhibits the ability to enhance the growth of wheat under drought stress. The complete genome sequence of this strain consists of one circular chromosome and two circular plasmids. From the genome, we identified genes related to the plant growth promotion and stress tolerance, such as nitrogen fixation, production of indole-3-acetic acid, acetoin, 2,3-butanediol, spermidine and trehalose. This genome sequence provides a basis for understanding the beneficial interactions between LTGPAF-6F and host plants, and will facilitate its applications as biotechnological agents in agriculture.
