Resurrecting urban sunflowers: Phenotypic and molecular changes between antecedent and modern populations separated by 36 years

open access: yesMolecular Ecology, Volume 32, Issue 19, Page 5241-5259, October 2023., 2023
Abstract Resurrection experiments provide a unique opportunity to evaluate phenotypic and molecular evolution in response to environmental challenges. To understand the evolution of urban populations of Helianthus annuus, we compared plants from 36‐year‐old antecedent seed collections to modern seed collections from the same area using molecular and ...

Integrating genome‐wide association mapping of additive and dominance genetic effects to improve genomic prediction accuracy in Eucalyptus

open access: yesThe Plant Genome, Volume 15, Issue 2, June 2022., 2022
Abstract Genome‐wide association studies (GWAS) is a powerful and widely used approach to decipher the genetic control of complex traits. Still, a significant challenge for dissecting quantitative traits in forest trees is statistical power. This study uses a population consisting of 1,123 samples derived from two successive generations of crosses ...

On the capacity for rapid adaptation and plastic responses to herbivory and intraspecific competition in insular populations of Plectritis congesta

open access: yesEvolutionary Applications, Volume 15, Issue 5, Page 804-816, May 2022., 2022
Abstract A capacity for rapid adaptation should enhance the persistence of populations subject to temporal and spatial heterogeneity in natural selection, but examples from nature remain scarce. Plectritis congesta (Caprifoliaceae) is a winter annual that exhibits local adaptation to browsing by ungulates and hypothesized to show context‐dependent ...

Experimental evaluation of genomic selection prediction for rust resistance in sugarcane

open access: yesThe Plant Genome, Volume 14, Issue 3, November 2021., 2021
Abstract The total sugarcane (Saccharum L.) production has increased worldwide; however, the rate of growth is lower compared with other major crops, mainly due to a plateauing of genetic gain. Genomic selection (GS) has proven to substantially increase the rate of genetic gain in many crops.

Génétique de la Sclérose En Plaques: Héritabilité manquante et Charge génétique

open access: yes, 2013
Multiple Sclerosis (MS) is a multifactorial disease, resulting from an interaction between genetics and unknown environmental factors. During the last years, the identification of several predisposing genetic polymorphisms constituted a real breakthrough

Heritabilité des caractères de croissance chez des poules de race locale âgées de 6 semaines au Nigeria

open access: yesRevue d’Elevage et de Médecine Vétérinaire des Pays Tropicaux, 1994
Les valeurs de l'héritabilité du poids corporel, de la longueur de la cuisse, de celle du bréchet et de la profondeur de la poitrine pour les poules indigènes du Nigeria âgés de 6 semaines, ont été obtenues à partir des données d'un modèle imbriqué ...

Résistance à la cowdriose de chèvres Créole en Guadeloupe. Bilan en 1988

open access: yesRevue d’Elevage et de Médecine Vétérinaire des Pays Tropicaux, 1991
Le taux de résistance à la cowdriose de chèvres Créole en Guadeloupe, varie beaucoup suivant les contacts antérieurs avec la cowdriose. Le taux de résistance à une infection expérimentale varie de 25 %, pour des chèvres vivant en dehors des zones d ...

Genetic mapping of biomass yield in three interconnected Miscanthus populations

open access: yesGCB Bioenergy, Volume 10, Issue 3, Page 165-185, March 2018., 2018
A consensus genetic map of Miscanthus sinensis and Miscanthus sacchariflorus was developed via linear programming algorithm with 7618 single‐nucleotide polymorphism markers generated from restriction site‐associated DNA sequencing. We confirmed the whole‐genome duplication in Miscanthus relative to Sorghum bicolor. Abstract Improving biomass yield is a
