Research Progress on Mechanism of Brassinosteroids Regulating Plant Salt Tolerance

doi:10.13304/j.nykjdb.2022.0923

Abstract

Abstract:

Brassinosteroid（BR）， as a novel and highly efficient plant hormone， is widely involved in various physiological processes of plants and has important roles in alleviating abiotic stresses. This article elaborated the biological functions of BR treatment in alleviating salt stress， and summarized the BR signaling pathways in Arabidopsis thaliana， rice and several horticultural plants. By introducing the salt tolerance mechanism of BR， it further analyzed the response signal transduction pathways when the plants subjected to salt stress， which provided a theoretical basis for the application of BR in improving salt tolerance in plants.

Key words: brassinosteroid, plant hormone, salt tolerance, action mechanism

摘要：
