Identification and functional characterization of JrbZIP40 in walnut reveals its role in salt and drought stress tolerance in transgenic Arabidopsis seedlings.

ABSTRACT:

Background

Salt and drought are the primary environmental stress factors that severely threaten plant growth, development, and yield. bZIP transcription factors reportedly play crucial roles in plant responses to both biotic and abiotic stressors. However, the biological function of bZIP transcription factors in oil crops, particularly walnuts, under salt and drought stress remains unclear.

Results

In this study, members of the walnut bZIP gene family were identified based on the walnut genome Chandler 2.0. Transcriptome data and RT-qPCR results were used to analyze the expression patterns of various JrbZIP genes under biotic and abiotic stress, revealing that JrbZIP40 was strongly induced by both drought and salt stress.
