□ Purpose&Contents
This research aimed to aquire bacterial strains improving salt-tolerance of crops by plant-microbe interactions
- Isolation of symbiotic rhizosphere and/or endophytic bacteria for enhancing salt-tolerance of selected crops
- Development of eco-friendly ecological technology to improve salt-tolerance of crops
- Aquisition of microbial resources for crop salt-tolerance

□ Results
○ Isolation of salt-tolerant microorganisms from rhizosphere crop soils and aquisition of biological resources
- 8 strains of Bacillus that capable of promoting barley growth in the high concentration of salt in soil
○ Promotion of barley growth in soil with high salinity (4% NaCl) by applying the isolated microorganisms
- Increased total chlorophyll contents of the crops (barley) by microbial inoculation compared to the uninoculated control

□ Expected Contribution
○ Science and technology aspects
- Plant-microbial symbiosis without genetic modification technology, which has been the mainstay of crop salt resistance improvementtechnology, will contribute as a solid agricultural technology for cropgrowth promotion in the salt soils.
- Plant - microbial interrelationships will contribute to the expansion and development of the field of study on not only nitrogen fixation andplant growth promotion, but also the interaction of plants to overcomeenvironmental stress such as salt tolerance.
- It is expected that the basic knowledge derived from this project and its application results will become a typical model that will be put to practical use in industry and contribute greatly to the development of domestic science.

○ Socio-economic aspects
- The technology to improve crop salt resistance by application of symbiotic relationship between salt tolerant microorganisms and crops is an environmentally friendly and sustainable method that does not applytechnology such as genetic modification and can be used in high salinityareas such as reclaimed land. It is expected that there will be economicand industrial aspects to increase food self-sufficiency rate and strengthen food security in Korea.
- By applying crop cultivation techniques to overcome environmental stresses including the enhancement of salt tolerance of crops presented through this research project, we will propose a new business model for crop adaptation against climate change and provide food security that is a potential global threat. We expect to be able to mitigate the problem.
- As the need for salt-tolerant crops is increasing in China, the demand for agricultural products is increasing and the income level of agricultural workers is expected to increase by the developed technologies.
