A Promising Herbicide-Resistant Bacterial Strain of Pseudomonas protegens for Stimulation of the Growth of Agricultural Cereal Grains

The bacterial strain Pseudomonas protegens DA1.2 was isolated from anthropogenic disturbed soil, studied, and identified. The isolate has potential for use in crop production: it synthesizes indolylacetic acid, promotes the mobilization of phosphorus from insoluble compounds, has nitrogenase activit...

Description
Summary:The bacterial strain Pseudomonas protegens DA1.2 was isolated from anthropogenic disturbed soil, studied, and identified. The isolate has potential for use in crop production: it synthesizes indolylacetic acid, promotes the mobilization of phosphorus from insoluble compounds, has nitrogenase activity, and shows antagonism against microscopic fungi from the genera Alternaria, Bipolaris, Botrytis, Fusarium , and Rhizoctonia . The strain remains viable in herbicidal (Octapon Extra, Florax, Chistalan, Nanomet, Spetsnaz, Dicamba) solutions that are widely used to process crops of cultivated cereals and can be used in tank mixtures containing these herbicides. On a lit site, the simultaneous spraying of wheat plants with herbicide and a liquid culture of P. protegens DA1.2 stimulates root and shoots growth and normalizes the chlorophyll and proline content in the leaves. Field experience from 2019 on the field of the Baimak Division of the Bashkir Research Institute of Agriculture of the Ufa Federal Research Center of the Russian Academy of Science showed an 19–24% increase in yield after the use of bacterial culture against the background of the Nanomet and Chistalan herbicides. The results allow indicate that the culture of P. protegens DA1.2 is a promising growth stimulator and agent for a reduction of herbicide stress in wheat.
