Sterols and the phytosterol content in oilseed rape (Brassica napus L.)
Sterols are natural, organic compounds with a molecular nucleus of 17 carbon atoms and a characteristic threedimensional arrangement of four rings. From the chemical point of view sterols are steroid alcohols and their name is derived from Greek stereos, which mean solid with ending –ol, which is the suffix for alcohols. As essential constituents of cell membranes, they are widely distributed i...
متن کاملEpigenetic QTL mapping in Brassica napus.
There is increasing evidence that epigenetic marks such as DNA methylation contribute to phenotypic variation by regulating gene transcription, developmental plasticity, and interactions with the environment. However, relatively little is known about the relationship between the stability and distribution of DNA methylation within chromosomes and the ability to detect trait loci. Plant genomes ...
متن کاملHigh-Density SNP Map Construction and QTL Identification for the Apetalous Character in Brassica napus L.
The apetalous genotype is a morphological ideotype for increasing seed yield and should be of considerable agricultural use; however, only a few studies have focused on the genetic control of this trait in Brassica napus. In the present study, a recombinant inbred line, the AH population, containing 189 individuals was derived from a cross between an apetalous line 'APL01' and a normally petall...
متن کاملIdentification of Candidate Genes for Seed Glucosinolate Content Using Association Mapping in Brassica napus L.
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...
متن کاملMolecular Mapping and QTL for Expression Profiles of Flavonoid Genes in Brassica napus
Flavonoids are secondary metabolites that are extensively distributed in the plant kingdom and contribute to seed coat color formation in rapeseed. To decipher the genetic networks underlying flavonoid biosynthesis in rapeseed, we constructed a high-density genetic linkage map with 1089 polymorphic loci (including 464 SSR loci, 97 RAPD loci, 451 SRAP loci, and 75 IBP loci) using recombinant inb...
