The Hsf gene family, one of the most important transcription factor families, plays crucial roles in regulating heat resistance. However, a systematic and comprehensive analysis of this gene family has not been reported in Chinese cabbage. Therefore, systematic analysis of the Hsf gene family in Chinese cabbage has profound significance. In this study, 35(More)
Ascorbic acid (AsA) is an important antioxidant in plants and an essential vitamin for humans. Extending the study of AsA-related genes from Arabidopsis thaliana to Brassica rapa could shed light on the evolution of AsA in plants and inform crop breeding. In this study, we conducted whole-genome annotation, molecular-evolution and gene-expression analyses(More)
The sucrose non-fermenting 1-related protein kinase 2 (SnRK2) family members are plant-specific serine/threonine kinases that are involved in the plant response to abiotic stress and abscisic acid (ABA)-dependent plant development. Further understanding of the evolutionary history and expression characteristics of these genes will help to elucidate the(More)
The WRKY transcription factor is an important member of the stress-related transcription factors, which mediate diverse abiotic stresses in many plants. However, up until now, the number of WRKY members, and the regulatory mechanisms involved in abiotic stress responses in Pak-choi (Brassica campestris ssp. chinensis), remained unknown. We isolated and(More)
NAC (NAM, ATAF1/2 and CUC2) proteins represent a major plant-specific transcription factor (TF) family and are expressed in various developmental stages and tissues. In this study, 204 NAC genes, including 17 membrane-bound TFs, were identified in the Brassica rapa (Chinese cabbage) genome. The gene structure and motif compositions obtained suggest that the(More)
The MADS-box gene family is an ancient and well-studied transcription factor family that functions in almost every developmental process in plants. There are a number of reports about the MADS-box family in different plant species, but systematic analysis of the MADS-box transcription factor family in Brassica rapa (Chinese cabbage) is still lacking. In(More)
The genomes of non-heading Chinese cabbage (Brassica rapa ssp. chinensis), heading Chinese cabbage (Brassica rapa ssp. pekinensis) and their close relative Arabidopsis thaliana have provided important resources for studying the evolution and genetic improvement of cruciferous plants. Natural growing conditions present these plants with a variety of(More)
In plants, flowering is the most important transition from vegetative to reproductive growth. The flowering patterns of monocots and eudicots are distinctly different, but few studies have described the evolutionary patterns of the flowering genes in them. In this study, we analysed the evolutionary pattern, duplication and expression level of these genes.(More)
Non-heading Chinese cabbage (NHCC, Brassica rapa ssp. chinensis) is an important leaf vegetable grown worldwide. However, little is known about the molecular mechanisms underlying tolerance for extreme temperature in NHCC. The limited availability of NHCC genomic information has greatly hindered functional analysis and molecular breeding. Here, we conduct(More)
C-repeat binding factor (CBF) signaling pathway is involved in cold acclimation responsive to low temperature and some other stresses. CBF transcription factor family is the key component of this pathway. In this study, eight CBF-like genes, BrCBF1, BrCBF2, BrCBF3, BrCBF4, BrCBF5, and BrCBF6A/B/C were isolated from non-heading Chinese cabbage (Brassica(More)
