Detection of novel quantitative trait loci for cutaneous melanoma by genome-wide scan in the MeLiM swine model Inra
Du, Z.Q.; Vincent-Naulleau, S.; Gilbert, H.; Vignoles, F.; Créchet, F.; Shimogiri; Yasue; Leplat, J.J.; Bouet, S.; Gruand, J.; Horak; Milan, D.; Le Roy, P.; Geffrotin, C..
Human cutaneous melanoma is a complex trait inherited in about 10% of cases. Although 2 high-risk genes, CDKN2A and CDK4, and 1 low risk gene, MC1R, have been identified, susceptibility genes remain to be discovered. Here, we attempted to determine new genomic regions linked to melanoma using the pig MeLiM strain, which develops hereditary cutaneous melanomas. We applied quantitative trait loci (QTL) mapping method to a significant genome-wide scan performed on 331 backcross pigs derived from this strain. QTLs were detected at chromosome-wide level for a melanoma synthetic trait corresponding to the development of melanoma. The peak positions on Sus scrofa chromosomes (SSC) were at 49.4 and 88.0 cM (SSC1), 56.0 cM (SSC13), 86.5 cM(SSC15) and 39.8 cM...

Genomic regions involved in productivity of two specific poplar families in Europe. 2. Biomass production and its relationships with tree architecture and phenology Inra
Marron, N.; Storme, V.; Dillen, S.Y.; Bastien, C.; Ricciotti, L.; Salani, F.; Sabatti, M.; Rae, A.M.; Ceulemans, R.; Boerjan, W..
Short-rotation coppice of hybrid poplar is a promising renewable feedstock for biofuel production. Breeding for high biomass in short-rotation coppice has started only recently. Two hybrid poplar families were grown at two sites in Europe and phenotyped for a variety of biomass-related traits (1) to examine the extent of phenotypic and genetic variation in biomass production, ramification, resprouting, and phenology, (2) to search for genomic regions involved in productivity, and (3) to determine the effect of the environment on the expression of these traits. The performance of both families differed within and among sites. A pronounced heterosis was observed in most cases. Moderate to high heritability values were found. Seventeen quantitative trait loci...

Identification of QTL with effects on intramuscular fat content and fatty acid composition in a Duroc x Large White cross Inra
Sanchez, M.P.; Iannuccelli, N.; Basso, B.; Bidanel, J.P.; Billon, Y.; Gandemer, G.; Gilbert, H.; Larzul, C.; Legault, C.; Riquet, J.; Milan, D.; Le Roy, P..
Background: Improving pork quality can be done by increasing intramuscular fat (IMF) content. This trait is influenced by quantitative trait loci (QTL) sought out in different pig populations. Considering the high IMF content observed in the Durocpig, it was appealing to determine whether favourable alleles at a major gene or QTL could be found. The detection wasperformed in an experimental F2 Duroc × Large White population first by segregation analysis, then by QTL mapping usingadditional molecular information.Results: Segregation analysis provided evidence for a major gene, with a recessive Duroc allele increasing IMF by 1.8% in Durochomozygous pigs. However, results depended on whether data were normalised or not. After Box-Cox transformation,...

Mapping QTLs for grain dormancy on wheat chromosome 3A and the group 4 chromosomes, and their combined effect OAK
Mori, M.; Uchino, N.; Chono, M.; Chono, K.; Miura, Hideho.
A major QTL for grain dormancy, QPhs.ocs-3A.1, derived from the highly dormant wheat Zenkoujikomugi (Zen), has been identified in a study made under a controlled environment. Further investigations were needed to dissect the precise position and expression of QPhs.ocs-3A.1 under different field conditions because the ability to detect genetic loci for grain dormancy traits is compromised by environmental effects and genotype/environment interactions. Group 4 chromosomes have also been shown to be possible sites of QTLs for grain dormancy. The objectives of this study were (1) to locate additional molecular markers in the QPhs.ocs-3A.1 region, (2) to identify QTLs on the group 4 chromosomes and (3) to elucidate their combined effects. We examined the...

QTL analysis for leaf gas exchange in an apple progeny grown under atmospheric constraints Inra
Regnard, J.L.; Segura, V.; Merveille, N.; Durel, C.E.; Costes, E..
The capacity of the apple tree to tolerate temporary abiotic constraints was investigated through leaf responses to different vapor pressure deficits (VPD). A ‘Starkrimson’ x ‘Granny Smith’ F1 progeny of 125 full-sibs whip-grafted onto Pajam® 2 rootstocks and pot-cultivated was studied (three replicates). After two months, plants were transferred into a controlled environment chamber ensuring five increasing VPDs, from 0.7 to 2.7 kPa, other conditions remaining constant. Leaf stomatal conductance (gsw), net CO2 assimilation (An) and transpiration (E) rates were measured, and water use efficiency (WUE, An/E) computed. The leaf responses were analyzed through a linear model including genotype as random effect for each VPD level separately. Whatever the VPD,...

Quantitative trait loci and crop performance under abiotic stress: Where do we stand? Inra
Collins, N.C.; Tardieu, F.; Tuberosa, R..
The improvement of crop yield has been possible through the indirect manipulation of quantitative trait loci (QTLs) that control heritable variability of the traits and physiological mechanisms that determine biomass production and its partitioning. This article surveys how QTL-based approaches contribute to a better understanding of the genetic basis of crop performance under environmentally constrained conditions and critically analyzes how this knowledge can assist breeders accelerate the release of cultivars better able to cope with abiotic constraints.Crop performance is the end result of the action of thousands of genes and their interactions with environmental conditions and cultural practices. During the past century, conventional breeding has been...
