Key message: HSF family transcription factors were analyzed in genome of Chinese cabbage. Chromosomal locations showed that duplication might result in expansion. Response to abiotic stresses was elucidated in Chinese cabbage varieties. Abstract: The major heat shock factors regulating the heat stress response are heat shock transcription factors (HSFs), which interact with heat shock elements. In this study, Chinese cabbage (Brassica rapa L. ssp. pekinensis) HSFs were comprehensively analyzed. A total of 52 HSF family genes were identified for phylogenetic relationships and motif analysis based on the genome sequence of Chinese cabbage. All HSFs were divided into classes A, B, and C. The chromosomal locations and gene duplications of these HSFs were also presented. Nine potential duplication events were found in Chinese cabbage chromosomes. Expression of three HSF genes in two varieties of Chinese cabbage using quantitative real-time PCR revealed that BraHSF039 and BraHSF043 were up-regulated under temperature and salt stresses treatments, and only BraHSF043 gene was also down-regulated under salt stress in ‘Lubaisanhao’. BraHSF001 gene was down-regulated in the ‘Lubaisanhao’ variety under heat and cold stresses, under drought stress in ‘Qingdao 87-114’. These results can serve as a foundation for further studies on HSFs in Brassica.

Cryptotaenia japonica Hassk of the Apiaceae family serves as an important vegetable and a medicinal herb in Asia and North America. High temperature leads to serious damage during summer. Here, deep transcriptome sequencing was performed to obtain information on gene expression and heat shock protein genes in C. Japonica Hassk. A total of 40,734 unigenes were assembled and annotated. Gene Ontology and Clusters of Orthologous Groups were used to classify the functions of the unigenes. The pathway was also predicted based on Kyoto Encyclopedia of Genes and Genomes. The amounts of 2,791 simple sequence repeats were identified in 11,217 unigenes. To further investigate the expression under high temperature, 14 unigenes that encode CjHsp genes were selected based on the annotation of the Nr and Nt databases from C. japonica Hassk. The expression profiles of CjHsp genes under high-temperature treatments of 30 and 38 C were analyzed using qRT-PCR in C. japonica Hassk. Results showed that these CjHsp genes were regulated under high-temperature treatment. These findings provide the first information on C. japonica Hassk transcriptome and enhance understanding on the mechanisms of gene regulation under high-temperature stress in C. Japonica Hassk.
