Brassica species represent a broad range of crops. This reflects the high degree of genetic diversity and related phenotypic plasticity. An understanding of the genetic basis of Brassica diversity aids both breeding and the discovery of rare alleles and traits. Single Sequence Repeat (SSR) molecular markers are popular tools for assessing genetic diversity due to their high degree of polymorphi...

Flowering time adaptation is a major breeding goal in the allopolyploid species Brassica napus. To investigate the genetic architecture of flowering time, a genome-wide association study (GWAS) of flowering time was conducted with a diversity panel comprising 523 B. napus cultivars and inbred lines grown in eight different environments. Genotyping was performed with a Brassica 60K Illumina Infi...

Here, we report the identification of the Brassica-specific gene MS5d, which is responsible for male sterility in Brassica napus. The MS5d gene is highly expressed in the microsporocyte and encodes a protein that localizes to the nucleus. Light microscopy analyses have demonstrated that the MS5d gene affects microsporocyte meiosis in the thermosensitive genic male sterility line TE5A. Sequence ...

BACKGROUND Rapeseed-mustard is the second most important source of edible oil in India. Several species of Brassica are grown in different parts of country for its oilseeds. OBJECTIVE The objective was to investigate allergenicity to antigenic extracts of pollen of 4 species of Brassica. METHODS Brassica campestris, Brassica juncea, Brassica nigra, and Brassica napus were selected for the d...

one of the important mechanisms utilized by the plant growth promoting rhizobacteria (pgpr) is lowering of ethylene levels by the 1-aminocyclopropane-1-carboxylic acid (acc) deaminase enzyme. the mechanism facilitates plant growth and development in the stress conditions. pgpr containing acc deaminase can promote plant growth under stress and overcome the harmful effects. the study aimed to scr...

Rapeseed (Brassica napus L.) and mustard juncea are two important oilseed crops grown worldwide for edible oil meal production, as well as, a source of renewable energy. Silique shattering at the maturity stage is major cause seed yield reduction in brassica. Losses more developing countries due to poor management non-availability combine harvesters. resistance essential achieving good especial...

Detection of phytoplasma classified in phylogenetic group 16SrI, ‘Ca. Phytoplasma asteris’, in the plants of interspecific genotypes of Brassica oleracea x Brassica napus and their back-cross toward B. oleracea (IW7.7xB1) is reported in Poland. The presence of phytoplasmas in leaves of plants showing failure of flower bud formation but not in the asymptomatic hybrids was demonstrated by polymer...

Rapid and uniform seed germination is a crucial prerequisite for crop establishment and high yield levels in crop production. A disclosure of genetic factors contributing to adequate seed vigor would help to further increase yield potential and stability. Here we carried out a genome-wide association study in order to define genomic regions influencing seed germination and early seedling growth...

Drought stress can directly inhibit seedling establishment in canola (Brassica napus), resulting in lower plant densities and reduced yields. To dissect this complex trait, 140 B. napus accessions were phenotyped under normal (0.0 MPa, S0) and water-stressed conditions simulated by polyethylene glycol (PEG) 6000 (-0.5 MPa, S5) in a hydroponic system. Phenotypic variation and heritability indica...
