Summary: Rapeseed is an important oilseed crop and enhancing cold stress tolerance is crucial for agricultural investigation and crop improvement. This study identified stress-responsive genes, metabolites, and pathways in cold-tolerant and cold-sensitive rapeseed varieties. Functional analysis revealed the significance of starch and sucrose metabolism and phenylalanine metabolism in cold stress adaption. Six candidate genes were selected for controlling adaption to low temperature and showed significant differences in freezing tolerance.

Summary: Rapeseed is the third leading source of edible oil in the world, with genic male sterility lines playing a crucial role in harnessing heterosis for its hybrid production. Research on the pollen development in these GMS lines of rapeseed is limited, but studies have shown that abnormal development may occur at different stages. Through transcriptome analysis, numerous genes related to GMS have been identified, including key genes potentially involved in fertility regulation.

Summary: In this study, the DNA methylation pattern and its regulated pathway of winter rapeseed under freezing stress were explored using methylome and transcriptome analysis. The results showed that the average methylation level decreased under freezing stress, with CG methylation level being the highest. Functional enrichment analysis identified several differentially expressed genes associated with differentially methylated genes, including core transcription factors involved in plant response to stress.

Summary: This study identified 20S proteasome genes in rapeseed and studied their characteristics and expression patterns under various stress conditions. The genes were found to be distributed on all chromosomes of rapeseed and were duplicated on homoeologous chromosomes. Some of these genes showed high expression under abiotic and biotic stress conditions. These findings contribute to our understanding of the organization and function of 20S proteasome genes in rapeseed.

Summary: Root transcriptome analysis was conducted on 20 Brassica napus accessions with high and low potassium utilization efficiency (KUE) using RNA-seq. Differences in expression profiles of 71,437 genes were found between the two contrasting genotype groups. Functional classification analysis revealed that these differentially expressed genes were involved in hormone and signaling pathways, as well as glucose, lipid, and amino acid metabolism. Moreover, 33 transcription factors related to root development were identified. By combining differential expression analysis, gene co-expression network analysis, and genome-wide association study results, four candidate hub genes regulating root system formation were identified.

Summary: Exogenous serotonin was found to alleviate salt-induced growth inhibition in rapeseed seedlings by promoting biomass accumulation, increasing antioxidant enzyme activity, and enhancing solute content. It also reduced oxidative damage and increased chlorophyll content under salinity stress, ultimately mitigating the toxic effects of salt stress on rapeseed seedlings.

Summary: Due to climate change and expansion of cultivated areas, the yield potential of rapeseed is affected and it is susceptible to pests and pathogens. The study found that European genebanks have insufficient representation of different species in the rapeseed gene pool and the natural distribution of these species is expected to change. Therefore, strategies need to be developed to prevent the loss of wild relatives of rapeseed.

Summary: During the growth period of rapeseed, waterlogging stress can significantly affect its growth. In this study, the waterlogging-tolerant rapeseed line G230 and the waterlogging-sensitive rapeseed line G218 were identified through experiments. The results showed that G230 had lower leaf aging and root damage than G218 under waterlogging stress. Further analysis revealed that flavonoid biosynthesis and vitamin B6 metabolism played a key role in the waterlogging tolerance of rapeseed. These findings provide new insights for improving the waterlogging tolerance of rapeseed.

Summary: Winter rapeseed is an important oilseed crop in northwest China, but freezing stress severely limits its production and geographical distribution. The response mechanism of B. rapa to freezing stress remains unclear. Different cultivars of B. rapa showed unique differentially expressed genes before and after freezing stress, with the GO terms indicating different biological processes. Strong cold-tolerant cultivar exhibited higher basal freezing resistance and the activation of MAPK signal cascades in response to freezing stress.

Summary: This study compared two Brassica napus lines with different resistance levels to black rot disease and evaluated the differential gene expression during infection. The resistant line showed a gradual increase in differentially expressed genes (DEGs), while the susceptible line displayed a steady amount of DEGs. Analysis of gene co-expression networks identified multiple defense-related genes and enriched pathways associated with defense.

Summary: Trehalose acts as a growth modulator and improves cold stress tolerance in rapeseed seedlings. The study found that exogenous trehalose mitigates the adverse effects of cold stress on rapeseed seedlings, increasing their survival rate. Trehalose regulates antioxidant and osmotic balance, participates in metabolism and signaling networks to enhance cold stress tolerance.
