Abstract:
The study of genetic structure of a strain of diazotrophic bacteria isolated from the epiphytic community of rice plants (Oryza sativa L.) was carried out. The strain was identified as Agrobacterium tumefaciens 32 and deposited with VKSM under accession number RCAM04326. The results of studying the properties of the strain are given, including the assessment of nitrogenase activity in pure culture (549.7 nmol C2H4/ml/hour), the production of indolyl lactic acid (IMA) at the level of 229.6 ng/ml, as well as a stimulating effect on the development of the root system in legumes. crops (by 15-31%) and cereals (by 8-23%). The results of phylogenetic analysis showed the absence of Ti-plasmids in the genome structure of the new strain, which characterizes it as non-pathogenic.
