Diversity of cultivable endophytic bacteria associated with halophytes in Xinjiang of China and their plant beneficial traits

Endophytic bacteria from halophytes have a wide range of application prospects in various fields, such as plant growth-promoting, biocontrol activity and stress resistance. The current study aimed to identify cultivable endophytic associated with grown the salt-affected soil Xinjiang Uygur Autonomous Region, China evaluate their beneficial traits enzyme-producing activity. were isolated Reaumuria soongorica (PalL Maxim.), Artemisia carvifolia (Buch.-Ham. ex Roxb. Hort. Beng.), Peganum harmala L. Suaeda dendroides (C. A. Mey. Moq.) by using cultural-dependent method. Then we classified these based on difference between sequences 16S rRNA (16S ribosomal RNA) gene. Results showed that R. belonged genera Brucella, Bacillus Variovorax. Micromonospora Brucella. P. Paramesorhizobium, Peribacillus. S. genus Bacillus. Notably, was detected three above plants, indicating is common taxon halophytes. And, our results found about 37.50% tested strains strong protease-producing activity, 6.25% cellulase-producing 12.50% moderate lipase-producing Besides, all positive for IAA (3-Indoleacetic acid) production, 31.25% exhibited phosphate solubilization 50.00% weak siderophore production Our findings suggest are valuable resources identifying microbes ability increase host growth health soils.
