Because of their abundance and amenability to high-throughput genotyping techniques, Single Nucleotide Polymorphisms (SNPs) are powerful tools for efficient genetics genomics studies, including characterization genetic resources, genome-wide association studies genomic selection. In wheat, most the previous SNP discovery initiatives targeted coding fraction, leaving almost 98% wheat genome largely unexploited. Here we report on use whole-genome resequencing data from eight lines mine SNPs in...

Cultivated apple (Malus × domestica Borkh.) is one of the most important fruit crops in temperate regions, and has great economic cultural value. The genome highly heterozygous undergone a recent duplication which, combined with rapid linkage disequilibrium decay, makes it difficult to perform genome-wide association (GWA) studies. Single nucleotide polymorphism arrays offer multiplexed assays at relatively low cost per data point can be valid tool for identification markers associated...

Abstract Bread wheat (Triticum aestivum) inflorescences, or spikes, are characteristically unbranched and normally bear one spikelet per rachis node. Wheat mutants on which supernumerary spikelets (SSs) develop particularly useful resources for work towards understanding the genetic mechanisms underlying inflorescence architecture and, ultimately, yield components. Here, we report characterization of genetically unrelated leading to identification FRIZZY PANICLE (FZP) gene, encoding a member...

The amount and structure of genetic diversity in dessert apple germplasm conserved at a European level is mostly unknown, since all studies conducted Europe until now have been performed on regional or national collections. Here, we applied common set 16 SSR markers to genotype more than 2,400 accessions across 14 collections representing three broad geographic regions (North + East, West South) with the aim analyze extent, distribution variation resources Europe. A Bayesian model-based...

Deciphering the genetic control of flowering and ripening periods in apple is essential for breeding cultivars adapted to their growing environments. We implemented a large Genome-Wide Association Study (GWAS) at European level using an association panel 1,168 different genotypes distributed over six locations phenotyped these phenological traits. The was genotyped high-density SNPs Axiom®Apple 480 K SNP array. ran GWAS with multi-locus mixed model (MLMM), which handles putatively...

Selective breeding is a relatively recent practice in aquaculture species compared to terrestrial livestock. Nevertheless, the genetic variability of farmed salmonid lines, which have been selected for several generations, should be assessed. Indeed, significant decrease due high selection intensity could occurred, potentially jeopardizing long-term progress as well adaptive capacities populations facing change(s) environment. Thus, it important evaluate impact practices on diversity limit...

Crop wild relatives represent valuable sources of alleles for crop improvement, including adaptation to climate change and emerging diseases. However, introgressions from might have deleterious effects on desirable traits, yield, due linkage drag. Here, we analyzed the genomic phenotypic impacts in inbred lines cultivated sunflower estimate First, generated reference sequences seven one genotype, as well improved assemblies two additional cultivars. Next, relying previously donor species,...

The evolution of sex determination (SD) in teleosts is amazingly dynamic, as reflected by the variety different master sex-determining genes identified. Pangasiids are economically important catfishes South Asian countries, but little known about their SD system. Here, we generated novel genomic resources for 12 and characterized Based on a Pangasianodon hypophthalmus chromosome-scale genome assembly, identified an anti-Müllerian hormone receptor type Ⅱ gene (amhr2) duplication, which was...

Abstract Background Carotenoids are isoprenoid pigments, essential for photosynthesis and photoprotection in plants. The enzyme phytoene synthase (PSY) plays an role mediating condensation of two geranylgeranyl diphosphate molecules, the first committed step carotenogenesis. PSY nuclear enzymes encoded by a small gene family consisting three paralogous genes ( 1-3) that have been widely characterized rice, maize sorghum.

Meiotic recombination by crossovers (COs) is tightly regulated, limiting its key role in producing genetic diversity. However, while COs are usually restricted number and not homogenously distributed along chromosomes, we show here how to disrupt these rules Brassica species using allotriploid hybrids (AAC, 2n = 3x 29), resulting from the cross between allotetraploid rapeseed (B. napus, AACC, 4x 38) one of diploid progenitors rapa, AA, 2x 20). We produced mapping populations different...

Rainbow trout is a significant fish farming species under temperate climates. Female reproduction traits play an important role in the economy of breeding companies with sale fertilized eggs. The objectives this study are threefold: to estimate genetic parameters female traits, determine architecture these by identification quantitative trait loci (QTL), and assess expected efficiency pedigree-based selection (BLUP) or genomic for traits.
