Sclerotinia stem rot (SSR) caused by the necrotrophic fungus Sclerotinia sclerotiorum is a major disease in rapeseed (Brassica napus) worldwide. Breeding for SSR resistance in B. napus, as in other crops, relies only on germplasms with quantitative resistance genes. A better understanding of the genetic basis for SSR resistance in B. napus thus holds promise for the genetic improvement of disea...

Rapeseed contains glucosinolates, a toxic group of sulfur-containing glucosides, which play critical roles in defense against herbivores and microbes. However, the presence of glucosinolates in rapeseed reduces the value of the meal as feed for livestock. We performed association mapping of seed glucosinolate (GS) content using the 60K Brassica Infinium single nucleotide polymorphism (SNP) arra...

Evening Primrose (Oenothera biennis L.) is an industrial crop-producing seed with high oil concentration characterized by gamma-linoleic acid. However, limited information available on its response to the nutrient supply, especially P and K. The aim of this work was compare application N, P, K alone or in combination a deficient soil terms grain yield, yield components, composition comparison R...

Planning the artificial pollination of agricultural crops requires knowledge of the floral biology and reproductive system of the crop in question. Many studies have shown that rapeseed (Brassica napus Linnaeus) is self-compatible and self-pollinated, but its productivity may be increased by insect visitation. In the present study, the floral biology and the response of productivity to insect v...

Brassica napus L. provides high-quality edible oil and clean energy for humans. For a long time, rapeseed breeders have tried to breed improved varieties through traditional breeding strategies. However, B. is an allotetraploid species containing many repetitive sequences. It very inefficient change traits genetic methods such as hybridization random mutagenesis due gene redundancy. Today, the ...

With a large and growing demand in the market, rapeseed (Brassica napus subsp. napus.) is crop with relatively high requirements for macronutrient fertilization. The aim of experiment was to study effect mineral fertilization different doses nitrogen phosphorus on accumulation microelements vegetative organs grains oilseed rape plants.The carried out long-term experimental fields SCDA Livada. T...

Polima and Shaan 2A are the two most widely used forms of cytoplasmic male sterility (CMS) in the utilization of heterosis of rapeseed (Brassica napus) in China. A previous study indicated that the mitochondrial gene, orf224, was the only gene with a differential expression pattern among the normal, sterile and fertility-restored lines in rapeseed. DNA sequences of orf224, including coding sequ...

A novel cytoplasmic male sterility (CMS) in Brassica napus (inap CMS) was selected from the somatic hybrid with Isatis indigotica (Chinese woad) by recurrent backcrossing. The male sterility was caused by the conversion of tetradynamous stamens into carpelloid structures with stigmatoid tissues at their tips and ovule-like tissues in the margins, and the two shorter stamens into filaments witho...

The basic region/leucine zipper motif (bZIP) transcription factor family is one of the largest families of transcriptional regulators in plants. bZIP genes have been systematically characterized in some plants, but not in rapeseed (Brassica napus). In this study, we identified 247 BnbZIP genes in the rapeseed genome, which we classified into 10 subfamilies based on phylogenetic analysis of thei...
