Genetic models for polyploid crop adaptation provide important information relevant for future breeding prospects. A well-suited model is Brassica napus, a recent allopolyploid closely related to Arabidopsis thaliana. Flowering time is a major adaptation trait determining life cycle synchronization with the environment. Here we unravel natural genetic variation in B. napus flowering time regula...

s. Therefore, more information is necessary concerning cauliflower transplant age. CHINESE CABBAGE [Brassica rapa L. SSP. PEKINENSIS (LOUR.)]. Kratky et al. (1982) in Hawaii found no significant differences in time to maturity, individual head weight, and total yield from Chinese cabbage transplants of 3, 4, 5, and 6 weeks of age. RAPE (Brassica napus ssp. OLEIFERA VAR. NAPUS). In a 3-year stud...

Brassica napus is an allotetraploid (AACC) formed from the fusion of two diploid progenitors, Brassica rapa (AA) and Brassica oleracea (CC). Polyploidy and genome-wide rearrangement during the evolution process have resulted in genes that are present as multiple homologs in the B. napus genome. In this study, three B. napus homologous genes encoding endoplasmic reticulum-bound sn-glycerol-3-pho...

MicroRNAs (miRNAs) and small interfering RNAs are important regulators of plant development and seed formation, yet their population and abundance in the oil crop Brassica napus are still not well understood, especially at different developmental stages and among cultivars with varied seed oil contents. Here, we systematically analyzed the small RNA expression profiles of Brassica napus seeds a...

Meiotic crossovers (COs) are essential for proper chromosome segregation and the reshuffling of alleles during meiosis. In WT plants, the number of COs is usually small, which limits the genetic variation that can be captured by plant breeding programs. Part of this limitation is imposed by proteins like FANCM, the inactivation of which results in a 3-fold increase in COs in Arabidopsis thalian...

Introduction Assessment of the mating system of a crop is particularly important for the design of adequate breeding and genetic conservation programs. Genetic inbreeding and heterosis, important factors that affect the production of the crop, are related to the mating system. Brassica napus L. includes economically important crops, such as oilseed rape, rutabaga and leaf rape. B. napus is cons...

The Resistance to Powdery Mildew 8 (RPW8) locus confers broad-spectrum resistance to powdery mildew in Arabidopsis thaliana. There are four Homologous to RPW8s (BrHRs) in Brassica rapa and three in Brassica oleracea (BoHRs). Brassica napus (Bn) is derived from diploidization of a hybrid between B. rapa and B. oleracea, thus should have seven homologs of RPW8 (BnHRs). It is unclear whether these...
