Description

The present invention relates to a Bacillus ariabatta strain which promotes abiotic stress resistance of a plant and a use thereof for the production of Bacillus arybhattai strain against abiotic stress and use thereof.

The present invention relates to a Bacillus ariabatai strain and its use for promoting abiotic stress resistance of a plant, and more particularly to a Bacillus aryabhattai strain H26-2 having excellent resistance to a plant in a high temperature drying environment No. KACC 92165P), a composition for promoting stress resistance of plants using the same, a method for enhancing stress resistance of plants, and a method for promoting plant growth.

Excessive amounts of chemical fertilizers have been used in agriculture around the world to provide nutrients to support plant growth. While chemical fertilizers have provided benefits to modern agriculture, it has been observed that increased use of chemical fertilizers degrades the composition and quality of the land. Therefore, the abuse of chemical fertilizer causes soil compaction and corrosion, resulting in lowering of production rate and lowering of utilization efficiency of fertilizer.

In addition, since seed and fruit production are fundamentally limited by biological and abiotic stresses, for example, drought stress, salt stress, nutrient deficiency, heavy metal contamination, extreme temperature or immersion can cause plant growth and productivity It is an additional key factor limiting. For example, soybean (Glycine max) suffers from loss of seed germination ability during storage and is a germinable species that can not germinate when soil temperature is low, and corn and other plants are important in crop science. Improvement of abiotic stress resistance in plants is believed to be due to the fact that growing bodies are growing and growing in low temperature, drought, flood, high temperature, UV stress, ozone increase, acid rain, pollution, salt stress, heavy metals, mineralized soil, Germination will be increased and there will be an advantage in crops. In addition, biological stresses such as fungal and viral infections cause many grain losses worldwide.

As a result, fertilizer and pesticides that are being used excessively are threatening the natural environment and human health at the present time. In order to maintain the productivity and increase the income of the farm households, Interest is growing in the development of eco-friendly functional agricultural materials using microorganisms.

For example, crop cultivation methods using soil microorganisms have recently been used as one of eco-friendly agricultural techniques. Currently, cultivation of crops using soil microorganisms is widely performed in soybean plants. Microorganisms mainly used for the cultivation of these crops include (i) nitrogen fixation ability to convert gas phase nitrogen to hydrogen-bonded ammonia nitrogen (NH ₃ ) Rhizobium, which allows plants to survive; (ii) Plant growth-promoting rhizobacteria (PGPR), which promotes the growth of plants without having symbiotic relationships with host plants , Abu joss buffer rilreom spp (Azospirrilum spp.) for fixing the air nitrogen and Pseudomonas spp (Pseudomonas spp.), etc. this is typical. These plant growth promoting microorganisms are known to help plant growth by various functions such as fixation of public nitrogen, promotion of nutrient absorption of plants, and inhibition of plant disease.

In addition, studies on the use of microorganisms that produce organic acids have been continuing as one of the methods for solubilizing the insoluble phosphoric acid accumulated in the soil, one of the important plant nutrients in the soil. Studies on the phosphate-solubilizing bacteria have been conducted in Russia and Eastern Europe After the announcement of the effect of increasing the number of crops due to the development of microbial fertilizer, many studies are underway in Korea and abroad. However, solubilization of such phosphorus is mainly performed by acidification in the medium, but it is not easy to apply this method to actual soil having buffering ability for pH. Therefore, it is not only excellent in the action of producing substances promoting the growth of plants, but also by inoculating the soil with a microorganism (phosphate-solubilizing microorganism, PSM) capable of directly solubilizing the insoluble phosphoric acid immobilized on the soil, It would be beneficial to increase plant productivity and further reduce the environmental pollution as well as the economic effect on the agricultural industry.

In this way, methods to promote soil nutrition and release plant nutrients from organic matter can increase plant growth and mitigate environmental stresses to plants play a major role in increasing plant production, There is a continuing need to develop methods.
