An ultradense genetic linkage map with >10,000 AFLP loci was constructed from a heterozygous diploid potato population. To our knowledge, this is the densest meiotic recombination ever constructed. A fast marker-ordering algorithm used, based on minimization of total number events within given marker order in combination genotyping error-detection software. This resulted "skeleton bin maps," which can be viewed as most parsimonious order. The unit distance not expressed centimorgans but...
Significance This study provides a deep population genomic analysis of 10,000 Capsicum accessions held in genebanks and representing frame the global diversity genus. By combining single nucleotide polymorphisms (SNPs) based data passport information, we investigated structure wild domesticated peppers, tracing back to routes evolution providing model annuum distribution, which reflects human trade historical/cultural influences. Our results highlight west–east expansion, shedding light on...
The Nc(tbr) and Ny(tbr) genes in Solanum tuberosum determine hypersensitive reactions, characterized by necrotic reactions restriction of the virus systemic movement, toward isolates belonging to clade C O Potato Y (PVY), respectively. We describe a new resistance from S. sparsipilum which possesses same phenotype specificity as is controlled dominant gene designated Nc(spl). Nc(spl) maps on potato chromosome IV close or allelic Ny(tbr). helper component proteinase (HC-Pro) cistron PVY was...
Plant resistance to nematodes is related the ability of host reduce development nematode juveniles into females. Resistance potato cyst (PCN) Globodera pallida, originating from wild species Solanum sparsipilum, was dissected by a quantitative trait loci (QTL) approach. Two QTL explained 89% phenotypic variation. The GpaV s spl on chromosome V displayedthe major effect number (coefficient determination [R 2 ] = 76.6%). It restricted G. pallida 16.2% juveniles, 81.5% males, and 2.3% GpaXI XI...
Abstract Segregation data were obtained for 1260 potato linkage group I-specific AFLP loci from a heterozygous diploid population. Analytical tools that identified potential typing errors and/or inconsistencies in the and assembled cosegregating markers into bins applied. Bins contain multiple-marker sets with an identical segregation pattern, which is defined as bin signature. The signatures used to construct skeleton map was based solely on observed recombination events. Markers did not...
With the banning of most chemical nematicides, control root-knot nematodes (RKNs) in vegetable crops is now based essentially on deployment single, major resistance genes (R-genes). However, these are rare and their efficacy threatened by capacity RKNs to adapt. In pepper, several dominant R-genes effective against RKNs, durability have been shown be greater a partially resistant genetic background. determinants this partial were unknown. Here, quantitative trait loci (QTL) analysis was...
ABSTRACT The first vanilla genetic linkage map was constructed by analyzing the progeny of an interspecific cross between Vanilla × tahitensis J. W. Moore (pro sp.) and pompona Schiede. two‐way pseudotestcross mapping strategy used a total 225 amplified fragment length polymorphism (AFLP) markers were mapped on 18 groups covering 1035.85 cM. Thirteen tahitian morphotypes, one planifolia Andrews recent hybrids compared measuring seven morphological traits genotyping, with 539 AFLP fragments....
Using a complementary (c)DNA-amplified fragment length polymorphism (AFLP) approach, we investigated differential gene expression linked to resistance mechanisms during the incompatible potato – Globodera pallida interaction. Expression was compared between resistant and susceptible clone, inoculated or not with G. pallida. These clones were issued from cross Solanum sparsipilum spl329.18 accession dihaploid S. tuberosum Caspar H3, carried, respectively, alleles at quantitative trait loci...
Abstract The essential oils obtained from roots of three Angelica L. species growing in France were analyzed by GC/MS. dominant component the root oil archangelica subsp. var. norvegica (Rupr.) Rikli, was δ-3-carene (13.0%), while major A. sylvestris elatior Wahlenb. and heterocarpa Lloyd nonane (18.7% 5.2% respectively). One result this study that numerous volatile components found have never before been described as constituents two examined. chemical analyses present systematic markers...
The potato cyst nematodes Globodera rostochiensis and pallida are quarantine pests. Present worldwide, they cause serious damage to crops. Seed production is only authorized in non-infected soils preventive measures taken. In infested areas, the use of appropriate agronomical practices choice resistant genotypes aim at restricting or preventing nematode multiplication. Where climatic conditions allow solarisation soil, this method can efficiently replace chemical treatments that eventually...
Partial resistance in plants generally exerts a low selective pressure on pathogens, and thus ensuring their durability agrosystems. However, little is known about the effect of partial molecular mechanisms pathogenicity, knowledge that could advance plant breeding for sustainable health. Here we investigate gene expression Phytophthora capsici during infection pepper (Capsicum annuum L.), where only genetic reported, using Illumina RNA-seq. Comparison transcriptomes P. infecting susceptible...
