Transcriptomic and metabolomic analysis reveal the cold tolerance mechanism of common beans under cold stress.

ABSTRACT:

Background

Common bean (Phaseolus vulgaris L.) is a thermophilic crop, and exposure to cold stress can significantly impact their yield and quality. To elucidate the impact of cold stress on cold-tolerant 'Wei Yuan' (WY) and cold-sensitive 'Bai Bu Lao' (BBL) of common bean, the mechanism of cold tolerance was studied by physiological and biochemical and multi-omics analysis.

Results

In this study, lower relative conductivity and higher malondialdehyde content after cold stress endowed 'WY' seedlings with cold tolerance. A total of 11,837 differentially expressed genes (DEGs) and 923 differential metabolites (DEMs) were identified by transcriptome and metabolomics analysis. Joint analysis showed that under cold stress, DEGs and DEMs in common beans are extensively engaged in
