Abstract Brassica napus (2 n = 4 x 38, AACC) is an important allopolyploid crop derived from interspecific crosses between rapa 2 20, AA) and oleracea 18, CC). However, no truly wild B. populations are known; its origin improvement processes remain unclear. Here, we resequence 588 accessions. We uncover that the A subgenome may evolve ancestor of European turnip C common kohlrabi, cauliflower, broccoli, Chinese kale. Additionally, winter oilseed be original form . Subgenome-specific...
Yield is one of the most important yet complex crop traits. To improve our understanding genetic basis yield establishment, and to identify candidate genes responsible for improvement in Brassica napus, we performed genome-wide association studies (GWAS) seven yield-determining traits [main inflorescence pod number (MIPN), branch (BPN), per plant (PNP), seed (SPP), thousand weight, main (MIY), yield], using data from 520 diverse B. napus accessions two different environments. In total,...
Abstract Harvest index (HI), the ratio of seed mass to total biomass aboveground plant parts, is an important trait for harvestable yield crops. Unfortunately, HI Brassica napus lower than that other economically To identify candidate genes associated with high HI, a genome-wide association study and four HI-related traits was conducted 520 B. accessions cultivated in both Yunnan Chongqing. We detected 294 single nucleotide polymorphisms significantly abovementioned traits, including 79 SNPs...
Increasing seed oil content is one of the most important targets for rapeseed (Brassica napus) breeding. However, genetic mechanisms mature in Brassica napus (B. remain little known. To identify content-related genes, a genome-wide association study (GWAS) was performed using 588 accessions.High-throughput genome resequencing resulted 385,692 high-quality single nucleotide polymorphism (SNPs) with minor allele frequency (MAF) > 0.05. We identified 17 loci that were significantly associated...
In the past few decades, microalgae biofuel has become one of most interesting sources renewable energy. However, higher cost compared to that petroleum prevented production. Therefore, research on increasing lipid productivity from becomes more important. The production source, triacylglycerol biosynthesis in requires short chain fatty acids as substrates, which are synthesized chloroplasts. transport mechanism chloroplasts cytosol remains unknown.cDNAs two homologs Arabidopsis acid...
Brassica napus L. is a widely cultivated oil crop and provides important resources of edible vegetable oil, its quality determined by fatty acid composition content. To explain the genetic basis identify more minor loci for content, multi-locus random-SNP-effect mixed linear model (mrMLM) was used to genomic regions associated with content in genetically diverse population 435 rapeseed accessions, including 77 winter-type, 55 spring-type, 303 semi-winter-type accessions grown different...
Abstract Background In the oilseed crop Brassica napus (rapeseed), various metabolic processes influence seed oil content, quality, and biological yield. However, role of plastid membrane proteins in these traits has not been explored. Results Our genome-wide association study (GWAS) 520 B. accessions identified chloroplast protein-localized FATTY ACID EXPORTER 1-1 (FAX1-1) as a candidate associated with Seed transcript levels BnaFAX1-1 were higher cultivar high content relative to low-oil...
Harvest index (HI), the ratio of harvested seed weight to total aboveground biomass weight, is an economically critical value reflecting convergence complex agronomic traits. HI values in rapeseed ( Brassica napus ) remain much lower than other major crops, and underlying regulatory network largely unknown. In this study, we performed mRNA small RNA sequencing reveal mechanisms shaping B. during seed-filling stage. A 8,410 differentially expressed genes (DEGs) between high-HI low-HI...
Abstract Background Diacylglycerol kinases (DGKs) are signaling enzymes that play pivotal roles in response to abiotic and biotic stresses by phosphorylating diacylglycerol (DAG) form phosphatidic acid (PA). However, no comprehensive analysis of the DGK gene family had previously been reported B. napus its diploid progenitors ( rapa oleracea ). Results In present study, we identified 21, 10, 11 genes from , respectively, which all contained conserved catalytic domain were further divided...
Sugars are important throughout a plant’s lifecycle. Monosaccharide transporters (MST) essential sugar that have been identified in many plants, but little is known about the evolution or functions of MST genes rapeseed (Brassica napus). In this study, we 175 B. napus, 87 Brassica oleracea, and 83 rapa. These were separated into transport protein (STP), polyol transporter (PLT), vacuolar glucose (VGT), tonoplast monosaccharide (TMT), inositol (INT), plastidic (pGlcT), ERD6-like subfamilies,...
Increasing oil production is a major goal in rapeseed (Brassica napus) molecular breeding programs. Identifying seed content (SOC)-related candidate genes an important step towards achieving this goal. We performed quantitative trait locus (QTL) mapping of SOC B. napus using high-density SNP genetic map constructed from recombinant inbred lines and the Illumina InfiniumTM 60K array. A total 26 QTLs were detected three years on A01, A03, A05, A06, A09, C01, C03 C05, which accounted for...
