Stem rot caused by Sclerotinia sclerotiorum in many important dicotyledonous crops, including oilseed rape (Brassica napus), is one of the most devastating fungal diseases and imposes huge yield loss each year worldwide. Currently, breeding for resistance B. napus, as other can only rely on germplasms with quantitative genes. Thus, identification trait locus (QTL) S. resistance/tolerance this crop holds immediate promise genetic improvement disease resistance. In study, ten QTLs stem (SR) at...
Abstract An optimized plant architecture (PA) is fundamental for high-yield breeding but the genetic control of important trait largely unknown in rapeseed. Here factors (PAFs) were proposed to consist main inflorescence length proportion (MILP), branch height (BHP) and segment (BSP). Comparison different genotypes a DH population grown diverse environments showed that an PAF performance with MILP BHP between 0.3–0.4 was high yield potential. In total, 163 unique quantitative loci (QTLs) PA-...
Sclerotinia stem rot (SSR) caused by the necrotrophic fungus sclerotiorum is a major disease in rapeseed (Brassica napus) worldwide. Breeding for SSR resistance B. napus, as other crops, relies only on germplasms with quantitative genes. A better understanding of genetic basis napus thus holds promise improvement resistance. In present study, genome-wide association study (GWAS) were performed using an panel 448 accessions genotyped Brassica 60K Infinium® single-nucleotide polymorphism (SNP)...
Abstract Sclerotinia stem rot (SSR), caused by the necrotrophic fungus sclerotiorum , is one of most devastating diseases for several major oil-producing crops. Despite its impact, genetic basis SSR resistance in plants remains poorly understood. Here, through a genome-wide association study, we identify key gene, BnaA07. MKK9 that encodes mitogen-activated protein kinase confers oilseed rape. Our functional analyses reveal BnaA07.MKK9 interacts with BnaC03.MPK3 and BnaC03.MPK6...
Vegetable oil is an essential constituent of the human diet and renewable raw material for industrial applications. Enhancing production by increasing seed content in crops most viable, environmentally friendly, sustainable approach to meet continuous demand supply vegetable globally. An in-depth understanding gene networks involved biosynthesis during development a prerequisite breeding high-oil-content varieties. Rapeseed (Brassica napus) one important cultivated on multiple continents,...
Sclerotinia stem rot (SSR) caused by sclerotiorum (Lib.) de Bary is one of the most devastating diseases Brassica napus worldwide. Both SSR resistance and flowering time (FT) adaptation are major breeding goals in B. napus. However, early maturing rapeseed varieties, which important for rice-rapeseed rotation China, often highly susceptible to SSR. Here, we found that was significantly negatively correlated with FT a natural population containing 521 inbred lines double haploid (DH) 150...
Abstract Background Map-based cloning of quantitative trait loci (QTLs) in polyploidy crop species remains a challenge due to the complexity their genome structures. QTLs for seed weight B. napus have been identified, but information on candidate genes identified this important is still rare. Results In study, whole genetic linkage map was constructed using simple sequence repeat (SSR) markers that covered distance 2,126.4 cM with an average 5.36 between markers. A procedure developed...
Polyploidy plays a crucial role in plant evolution. Brassica napus (2n = 38, AACC), the most important oil crop genus, is an allotetraploid that originated through natural doubling of chromosomes after hybridization its progenitor species, B. rapa 20, AA) and oleracea 18, CC). A better understanding evolutionary relationship between rapa, oleracea, as well Arabidopsis, which has common ancestor with these three will provide valuable information about generation evolution allopolyploidy....
Summary Plant oils are valuable commodities for food, feed, renewable industrial feedstocks and biofuels. To increase vegetable oil production, here we show that the nonspecific phospholipase C6 (NPC6) promotes seed production in Brassicaceae species Arabidopsis, Camelina oilseed rape. Overexpression of NPC6 increased content, weight yield both Arabidopsis Camelina, whereas knockout decreased content size. is associated with chloroplasts microsomal membranes, hydrolyzes phosphatidylcholine...
Summary One of the most important goals in breeding oilseed crops, including Brassica napus , is to improve quality edible vegetable oil, which mainly determined by seed fatty acid composition, particularly C18:1 content. Previous studies have indicated that content a polygenic trait, and no stable quantitative trait loci ( QTL s) except for FAD 2 been reported. By performing GWAS using 375 low erucic B. accessions genotyped with 60K SNP array constructing high‐density ‐based genetic map 150...
Abstract The cultivated diploid Brassica oleracea is an important vegetable crop, but the genetic basis of its domestication remains largely unclear in absence high-quality reference genomes wild B. oleracea. Here, we report first chromosome-level assembly L. W03 genome (total size, 630.7 Mb; scaffold N50, 64.6 Mb). Using newly assembled genome, constructed a gene-based pangenome and identified 29 744 core genes, 23 306 dispensable 1896 private genes. We re-sequenced 53 accessions,...
Abstract Background Lipid transporters play an essential role in lipid delivery and distribution, but their influence on seed oil production oilseed crops is not well studied. Results Here, we examined the effect of two transporters, FAX1 ( fatty acid export1 ) ABCA9 ATP-binding cassette transporter subfamily A9 metabolism plant Camelina sativa . Overexpression (OE) increased weight size, with -OEs increasing length width, respectively, whereas / both. FAX1- OE ABCA9- displayed additive...
Single nucleotide polymorphism (SNP) markers have a wide range of applications in crop genetics and genomics. Due to their polyploidy nature, many important crops, such as wheat, cotton rapeseed contain large amount repeat homoeologous sequences genomes, which imposes huge challenge high-throughput genotyping with sequencing and/or array technologies. Allotetraploid Brassica napus (AACC, 2n = 4x 38) comprises two highly sub-genomes derived from its progenitor species B. rapa (AA, 2x 20)...
Patatinrelated phospholipases (pPLAs) are acylhydrolyzing enzymes implicated in various processes, including lipid metabolism, signal transduction, plant growth and stress responses, but the function for many specific pPLAs plants remains unknown. Here we determine effect of patatinrelated phospholipase A pPLAIIIγ on Arabidopsis response to abiotic stress. Knockout rendered more sensitive whereas overexpression enhanced tolerance NaCl drought seed germination seedling growth. The...
Brassica oleracea displays remarkable morphological variations. It intrigued researchers to study the underlying cause of enormous diversification this organism. However, genomic variations in complex heading traits are less known B. oleracea. Herein, we performed a comparative population genomics analysis explore structural (SVs) responsible for trait formation Synteny showed that chromosomes C1 and C2 (CC) shared strong collinearity with A01 A02 rapa (AA), respectively. Two historical...
Phosphatidic acid (PA) is considered as a second messenger that interacts with protein kinases, phosphatases and NADPH oxidases, amplifying the signal to initiate plant defense signaling responses (Li Wang, 2019). In rice, mutation of RBL1 causes accumulation PA, enhancing multipathogen resistance (Sha et al., 2023). our previous study, we attempted rescue rbl1 mutant by overexpressing phosphatidate phosphohydrolase ( PAH ) genes. However, overexpression PAH2 reduced PA level but did not...
