Physiological characteristics and transcriptome analysis of exogenous brassinosteroid-treated kiwifruit

In this work, we compared the effects of two different concentrations of BR on kiwifruit seedlings subjected to salt stress, and proved that BR has a mitigating effect on salt stress in kiwifruit seedlings from the aspects of photosynthesis, antioxidant and ion balance3. The high-throughput sequencing of transcriptome was used to analyze differential gene expression, and transcriptome data showed that multiple genes may be involved in the regulation of salt tolerance of BRs, and candidate genes such as CPK20, PP2C49, HKT1, and FSD were screened out in combination with physiological phenotypes.This provides new insights into the regulation of the salt tolerance mechanism of BRs in kiwifruit, which has certain significance for understanding and improving the cultivation of salt-tolerant kiwifruit.
