AI Technical Summary

Technical Problem

In the existing technology, plant endophytic fungi are difficult to isolate and cultivate in order to improve the salt tolerance of host plants. Foreign species behave unstably under competition from native microbial communities, and the role of non-dominant species has not been fully studied, making it difficult to effectively solve the problem of soil salinization.

Method used

The salt-tolerant endophytic fungus Bipolaris sp. 2Y-2 was screened out and, by establishing a co-cultivation system with poplar seedlings, was used to significantly improve the salt tolerance of plants under salt stress, reduce Na+ content, enhance photosynthetic capacity and antioxidant enzyme activity, and regulate ion homeostasis and photosynthetic pigment content.

Benefits of technology

It significantly improves the resistance of poplar seedlings to salt stress, reduces Na+ content, increases chlorophyll and carotenoid content, enhances photosynthetic rate and antioxidant enzyme activity, and provides an effective way to repair soil salinization.

Abstract

The invention discloses a salt-tolerant endophytic fungus and application thereof, the salt-tolerant endophytic fungus is bipolaris sp. 2Y-2, the classification name of the salt-tolerant endophytic fungus is Bipolaris sp., the salt-tolerant endophytic fungus is registered and preserved in Guangdong Microbial Culture Collection Center on January 2, 2025, and the preservation number of the salt-tolerant endophytic fungus is GDMCC No: 65710. According to the invention, endophytic fungi of key ecological niches such as roots, stems and leaves of salt-tolerant plants in a peripheral pollution area of the Zonggong salt mine are taken as research objects, and the salt-tolerant endophytic fungi Bipolaris sp. 2Y-2 is screened out through artificial separation and identification, so that the salt tolerance of the plants can be remarkably improved, more effective ways are provided for solving the problem of remediation of soil salinization, and the method has a wide application prospect. Meanwhile, a foundation is laid for development and practical application of a microbial agent.
