Stage of maturity at harvest is one of the most important factors that can influence the quality of seeds. This research was carried out in 2008- 2009 to evaluate the development of physiological seed quality in three winter oilseed rape (Brassica napus L.) cultivars (Modena, Opera and SLM046). Seeds were harvested serially in 9-10 stages during their development and maturation. Maximum seed weight (mass maturity) was achieved at 48-54 days after flowering, when seed moisture content was 41-50%. However, maximum seed quality as measured by seed viability, germination percentage, germination rate and seedling dry weight was obtained 10 to 22 days after mass maturity. Thereafter, seed quality of all cultivars was started to decrease, due to ageing. Maximum germination rate of SLM046 and maximum seedling dry weight of Opera were significantly higher than those of other two cultivars. These variations in seed quality parameters were attributed to differences in genetic constitution among oilseed rape cultivars. It was concluded that high quality seeds of winter oilseed rape cultivars could be produced with 14-16% moisture content, which is suitable for direct and mechanical harvesting, threshing and storage without further drying.

Rapeseed (Brassica napus L.) meal is an important source of protein, but the presence of anti-nutritional compounds, such as fibre and glucosinolates, still limits its use as a livestock feed. Understanding the genetic basis of seed fibre biosynthesis would help to manipulate its content in seeds of oilseed rape. Here, we applied high-resolution skim genotyping by sequencing (SkimGBS) and characterised 187,835 single-nucleotide polymorphism (SNP) markers across a mapping population subsequently used for a genetic mapping study (R/qtl). This approach allowed the identification of 11 stable QTL related to seed quality traits and led to the identification of potential functional genes underlying these traits. Among these, key genes with a known role in carbohydrate metabolic process, cell wall, lignin, and flavonoid biosynthesis, including cellulase GH5, TT10/LAC15, TT4, and SUC2, were found. This study furthers the understanding of the molecular mechanisms underlying seed fibre content and provides new markers for molecular breeding in B. napus.

Endophytic bacteria hold tremendous potential for use as biocontrol agents. Our study aimed to investigate the biocontrol activity of Pseudomonas fluorescens BRZ63, a new endophyte of oilseed rape (Brassica napus L.) against Rhizoctonia solani W70, Colletotrichum dematium K, Sclerotinia sclerotiorum K2291, and Fusarium avenaceum. In addition, features crucial for biocontrol, plant growth promotion, and colonization were assessed and linked with the genome sequences. The in vitro tests showed that BRZ63 significantly inhibited the mycelium growth of all tested pathogens and stimulated germination and growth of oilseed rape seedlings treated with fungal pathogens. The BRZ63 strain can benefit plants by producing biosurfactants, siderophores, indole-3-acetic acid (IAA), 1-aminocyclopropane-1-carboxylate (ACC) deaminase, and ammonia as well as phosphate solubilization. The abilities of exopolysaccharide production, autoaggregation, and biofilm formation additionally underline its potential to plant colonization and hence biocontrol. The effective colonization properties of the BRZ63 strain were confirmed by microscopy observations of EGFP-expressing cells colonizing the root surface and epidermal cells of Arabidopsis thaliana Col-0. Genome mining identified many genes related to the biocontrol process, such as transporters, siderophores, and other secondary metabolites. All analyses revealed that the BRZ63 strain is an excellent endophytic candidate for biocontrol of various plant pathogens and plant growth promotion.
