Summary: Volunteer B. napus is highly competitive with soybean, with low action (< 9 plants.m(-2)) and economic (<5 plants.m(-2)) thresholds. At these action thresholds, volunteer B. napus seed return to the weed seedbank was on average 14,400 seeds.m(-2) and 10,400 seeds.m(-2) in narrow and wide-row soybean, respectively.

Summary: This study assessed the genetic diversity of 383 globally distributed rapeseed germplasm using single nucleotide polymorphism markers. The results showed moderate genetic diversity within all subpopulations, with significant divergence between most combinations. Structure analysis and neighbor-joining tree analysis placed all subpopulations into three distinct clusters.

Summary: This study evaluated the effects of five strains of weed antagonistic bacteria on the growth and yield of wheat, finding that certain strains had significant positive effects on wheat parameters. The results suggest that these strains can be widely utilized for controlling noxious weeds in wheat and improving crop yield, with particular emphasis on the benefits of strains 7O(0) and L9 for weed control and growth promotion in wheat production.

Summary: This study evaluated the impact of conventional tillage (CT) and no-tillage (NT) systems on the yield, crop structure, weed infestation, and seed composition of winter oilseed rape. The results showed that the NT system had a beneficial effect on yield during precipitation shortage, while the CT system had higher seed yield in years with sufficient precipitation. The NT system was beneficial for seed weight and fat content, but had no effect on glucosinolate content. Weed density and weight were higher in the NT plot, with different weed species compared to the CT plot. Weed diversity was similar in both systems, but the NT system had higher dominance index.

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: The study found that the addition of tannery wastewater to the soil resulted in a significant decline in plant growth and biomass, as well as a reduction in antioxidant activity. However, foliar application of zinc and iron-lysine was able to mitigate chromium stress and enhance the uptake of essential micronutrients in plants.

Summary: In this study, differential expression of total protein in leaves of two transgenic oilseed rape lines and their non-transgenic parent plant was analyzed. Fourteen differential protein spots were identified, including eleven upregulated and three downregulated proteins, involved in photosynthesis, transporter function, metabolism, protein synthesis, and cell growth and differentiation. These changes in protein spots may be attributed to the insertion of foreign transgenes in transgenic oilseed rape, but transgenic manipulation does not necessarily cause significant changes in the proteomes of oilseed rape.

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: In this review, the authors summarize the role of cell wall-mediated defense responses in Brassica napus against pathogens. They find that pectin and lignin play important roles in immune responses in B. napus, and there is crosstalk between pectin and lignin metabolism in regulating cell wall integrity and immunity. The review also discusses the transcriptional regulation of cell-wall-mediated immunity in B. napus and proposes future directions for research.

Summary: The study identified mechanisms of resistance to ALS-inhibiting herbicides in a Bromus sterilis biotype, including reduced sensitivity to pyroxsulam, cross-resistance to other herbicides, and possible overexpression of target genes and enhanced metabolism by cytochrome P450s. These findings emphasize the need for monitoring herbicide resistance in brome populations in Europe and the use of alternate herbicides in integrated weed management to delay the evolution of resistance.

Summary: Native species play a significant role in arable weed communities in the Czech Republic. The occurrence of native species is influenced by management systems, crops, and environmental conditions, with altitude having the highest explanatory power. Organic farming and cereals show the highest occurrence of native weeds, which increase with higher altitudes.

Summary: This study investigated the molecular mechanisms of herbicide resistance in Apera spica-venti, focusing on ALS and ACCase target-site mutations as well as metabolic detoxification pathways. It was found that while target-site mutations were present for ALS and ACCase genes, metabolic detoxification played a role in resistance to certain herbicides. This research provides valuable insights for developing effective control strategies for weed management in the Czech Republic.
