Response to heat stress and glutenins allelic variation effects on quality traits in durum wheat
(Wiley, 2024-01-16)In the context of climate change, high temperature is one of the main abiotic stresses hampering durum wheat production. Through the characterization of an international panel of 271 genotypes, this study investigates the ... -
Population genetic characteristics and mating type frequency of Venturia effusa from Pecan in South America
(American Phytopathological Society, 2022-09-22)Scab, caused by the plant-pathogenic fungus Venturia effusa, is a major disease of pecan in South America, resulting in loss of quantity and quality of nut yield. Characteristics of the populations of V. effusa in South ... -
Assessing Payne score accuracy through a bread wheat multi-genotype and multi-environment set from CIMMYT
(Elsevier, 2024-01-01)The Payne score is a prevalent strategy for assessing wheat quality by considering the distinct contributions of specific high-molecular-weight glutenin subunits. Despite its extensive use, the limited germplasm used in ... -
Manipulation of the post-flowering source/sink ratio differentially affects protein composition and gluten quality in contrasting bread wheat genotypes
(Elsevier, 2024-03-28)Studies of the impact of assimilate availability during grain filling on protein composition and gluten quality of bread wheat are scarce. Therefore, this work aimed to analyze the responses of wet gluten percentage, SDS ... -
Efficient genomics-based ‘end-to-end’ selective tree breeding framework
(Springer Nature, 2024-01-03)Since their initiation in the 1950s, worldwide selective tree breeding programs followed the recurrent selection scheme of repeated cycles of selection, breeding (mating), and testing phases and essentially remained unchanged ... -
Genomic evaluation for breeding and genetic management in Cordia africana, a multipurpose tropical tree species
(BMC, 2024-01-02)Planting tested forest reproductive material is crucial to ensure the increased resilience of intensively managed productive stands for timber and wood product markets under climate change scenarios. Single-step Genomic ... -
Crop species transferability of G-SSR and EST-SSR markers to Neltuma affinis spreng
(Instituto Nacional de Investigación y Tecnología Agraria y Alimentaria (España), 2024-03-18)Aim of study: To examine the transferability of G-SSR (genomic simple sequence repeats) and EST-SSR (expressed sequence tag simple sequence repeats) markers developed for several Neltuma species to N. affinis, a species ... -
Optimizing a regional white spruce tree improvement program: SNP genotyping for enhanced breeding values, genetic diversity assessment, and estimation of pollen contamination
(MDPI, 2023-11-01)The utilization of genotyping has gained significant popularity in tree improvement programs, aiding in enhancing the precision of breeding values, removing pedigree errors, the assessment of genetic diversity, and evaluating ... -
Effects of the neonicotinoid insecticides Thiamethoxam and imidacloprid on metamorphosis of the toad rhinella arenarum at environmentally-relevant concentrations
