AI Technical Summary

Technical Problem

The lack of effective salt-tolerant genes in existing technologies, especially those derived from Miscanthus sinensis, leads to limited plant growth under salt stress, impacting agricultural production and the ecological environment.

Method used

The MsaH2A.W gene was cloned and identified from the Miscanthus genus Reed, and then transformed into plants using a recombinant expression vector to achieve gene overexpression, thereby improving the plant's salt tolerance and root growth.

Benefits of technology

It significantly improved the salt tolerance of transgenic plants, promoted their growth under salt stress conditions, enhanced their salt stress tolerance, and improved yield and quality.

Abstract

The application discloses a salt-tolerant gene MsaH2A.W from Miscanthus sacchariflorus and application thereof, and belongs to the technical field of biotechnology.A new salt-tolerant gene MsaH2A.W is cloned and identified from Miscanthus sacchariflorus for the first time.The MsaH2A.W gene is transformed into plants to be overexpressed, so that the salt-tolerant ability of the transgenic plants can be significantly improved, the root growth of the transgenic plants under salt stress is promoted, and then the yield and quality of the transgenic plants are improved.Therefore, the MsaH2A.W gene has very important significance for improving the growth of plants under salt stress.
