Physiological Characteristics and Transcriptome Analysis of Exogenous Brassinosteroid-Treated Kiwifruit.

ABSTRACT: Brassinosteroids (BRs) play pivotal roles in improving plant stress tolerance. To investigate the mechanism of BR regulation of salt tolerance in kiwifruit, we used 'Hongyang' kiwifruit as the test material. We exposed the plants to 150 mmol/L NaCl stress and irrigated them with exogenous BR (2,4-epibrassinolide). The phenotypic analysis showed that salt stress significantly inhibited photosynthesis in kiwifruit, leading to a significant increase in the H₂O₂ content of leaves and roots and a significant increase in Na⁺/K⁺, resulting in oxidative damage and an ion imbalance. BR treatment resulted in enhanced photosynthesis, reduced H₂O₂ content, and reduced Na⁺/K⁺ in leaves, alleviating the salt stress i
