Summary: The study revealed the crucial roles of TF families such as NAC, MYB, DOF, GATA, and HD-ZIP in seed oil content development, with their cooperative relationships and changes in gene expression profiles strongly associated with the differentiation of oil content between cultivars. These findings are significant for enhancing understanding of genetic programs in both cultivars and for developing new hypotheses for further experimental studies.

Summary: This study conducted a transcriptomic analysis of the relationship between seed weight and number in two rapeseed genotypes, revealing that a reduction in the source-sink ratio induced the expression of specific gene groups related to sucrose transport, seed weight, and stress responses. Additionally, the research identified co-expression modules correlated with seed weight and negatively correlated with seed number, with a significant enrichment of transcription factors in one module. Network analysis predicted NAC transcription factors as key regulators of seed weight and number compensation in rapeseed.

Summary: This study identified a major QTL, cqSC-A09, on chromosome A09 that controls seed color, oil content, and fiber content simultaneously in Brassica napus. This QTL has a large effect and can increase the oil content and reduce pigment and fiber content in seeds. The study also identified important candidate genes for cqSC-A09, which provides a foundation for further cloning and breeding applications. The results of this study have significant implications for breeding high oil quality rapeseed varieties.

Summary: This study evaluated 20 Brassica carinata genotypes and identified the 14C genotype as a potential edible oil cultivar due to its low erucic acid content. The genotypes 3C, 10C, and 17C were recommended for further breeding programs based on their low erucic acid content. Additionally, Brassica carinata cake from different genotypes showed potential as a valuable source of natural antioxidants.

Summary: Seaweed polysaccharides have been proven to be more effective than synthetic commercial fertilizers in promoting plant growth. This study extracted polysaccharides from different seaweeds and examined their impact on Brassica napus L. seed germination. Carrageenan showed the best results in seedling growth and germination percentage, which may be attributed to its sulphation level, pH and conductivity.

Summary: Camelina and canola, both non-transgenic cultivars, showed potential in reducing weed pressure and nutrient leaching in the upper Midwest and northern Great Plains of the USA. Sulfonylurea-resistant camelina and canola reduced late-season dry weight biomass of weeds by >75% and >= 60% respectively compared with fallow plots. However, the application of sulfonylurea herbicides did not significantly alter crop biomass, seed yield, and nutrient retention.

Summary: This study found that seed priming with silicon dioxide nanoparticles (SiO2 NPs) can alleviate the phytotoxicity of chromium (Cr) in Brassica napus seedlings. SiO2 NPs reduce the accumulation of Cr, enhance nutrient acquisition, improve photosynthetic performance, and boost plant immunity. SiO2 NPs have the potential to be used as stress-reducing agents for crops grown in Cr-contaminated areas.

Summary: In this study, a dwarf mutant of rapeseed named bnd2 was isolated using EMS mutagenesis. The mutant exhibited reduced plant height and was found to be a recessive mutation of a single locus. Through fine mapping, the candidate gene BnaA08g20960D was identified in a 140-Kb interval, potentially useful for breeding lodging resistant and high yield rapeseed.

Summary: The defatted rapeseed meal can be a valuable protein feed for livestock. However, the presence of antinutritional factors limits its use and marketing. In this study, a genome-wide association study (GWAS) was conducted to investigate the genetic architecture of various traits in rapeseed meal samples. Several genotypes with high-quality protein and fewer antinutrients were identified. Functional validation of candidate genes could enhance the protein quality and reduce antinutritional components in B. napus.

Summary: The study analyzed the genetic characteristics of seed germination under drought stress in a Brassica napus double haploid population and determined the drought stress index using QTLs analysis. Results showed that root-to-shoot length ratio is an effective morphological trait in determining drought tolerance in seedling stage. 39 identified QTLs were integrated into 36 consensus QTLs, with 18 QTLs affecting the drought stress index of four traits.

Summary: Sinapis alba and Sinapis arvensis are mustard crops that have important genetic potential for crop improvement. Through genomic analysis and comparison, it was found that both species retained evidence of a whole-genome triplication event approximately 20.5 million years ago. Subgenome dominance was observed in key genetic factors. The findings provide insights into the genome evolution and phylogenetic relationships of Brassiceae, and have implications for genetic improvement of these plants.

Summary: The chromosome-scale genome of Vigna unguiculata subsp. sesquipedalis was successfully reconstructed using high-fidelity long-read sequencing and high-throughput chromosome conformation capture technology. Genomic variations between subsp. sesquipedalis and subsp. unguiculata were identified, with some resulting in gene loss. The study also revealed the origin of subsp. sesquipedalis and identified genes functionally enriched in adaptations. Genome-wide association analysis uncovered quantitative trait loci for pod length and pod width, with strong signals of artificial selection.
