Transcriptome analysis and differential gene expression profiling of wucai (Brassica campestris L.) in response to cold stress.

ABSTRACT:

Background

Wucai suffers from low temperature during the growth period, resulting in a decline in yield and poor quality. But the molecular mechanisms of cold tolerance in wucai are still unclear.

Results

According to the phenotypes and physiological indexes, we screened out the cold-tolerant genotype "W18" (named CT) and cold-sensitive genotype "Sw-1" (named CS) in six wucai genotypes. We performed transcriptomic analysis using seedling leaves after 24 h of cold treatment. A total of 3536 and 3887 differentially expressed genes (DEGs) were identified between the low temperature (LT) and control (NT) comparative transcriptome in CT and CS, respectively, with 1690 DEGs specific to CT. The gene ontology (GO) analysis showed that the response to cadmium ion (GO:0,046,686), resp
