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,...
Abstract Genetic variation is of crucial importance for crop improvement. Landraces are valuable sources diversity, but quantitative traits efficient strategies their targeted utilization lacking. Here, we map haplotype-trait associations at high resolution in ~1000 doubled-haploid lines derived from three maize landraces to make native diversity early development accessible elite germplasm A comparative genomic analysis the discovered haplotypes landrace-derived and a panel 65 breeding...
Populations are locally adapted when they exhibit higher fitness than foreign populations in their native habitat. Maize landrace adaptations to highland and lowland conditions of interest researchers breeders. To determine the prevalence strength local adaptation maize landraces, we performed a reciprocal transplant experiment across an elevational gradient Mexico. We grew 120 grouped into four (Mexican Highland, Mexican Lowland, South American Lowland), common gardens collected phenotypes...
The spread of maize cultivation to the highlands central Mexico was accompanied by substantial introgression from endemic wild teosinte Zea mays ssp. mexicana, prompting hypothesis that transfer beneficial variation facilitated local adaptation.We used whole-genome sequence data map regions mexicana in three Mexican highland individuals. We generated a genetic linkage and performed Quantitative Trait Locus mapping an F2 population derived cross between lowland individuals.Introgression...
Abstract Generations of farmer selection in the central Mexican highlands have produced unique maize varieties adapted to challenges local environment. In addition possessing great agronomic and cultural value, highland represents a good system for study adaptation acquisition adaptive phenotypes under cultivation. this study, we characterize recombinant inbred line population derived from B73 reference variety Palomero Toluqueño. Toluqueño showed classic rank-changing differences...
Background Gene regulatory variation has been proposed to play an important role in the adaptation of plants environmental stress. In central highlands Mexico, farmer selection generated a unique group maize landraces adapted challenges highland niche. this study, gene expression Mexican and reference breeding line were compared identify evidence stress-related genes. It was hypothesised that local would be associated with transcriptional signature observable even under benign conditions....

High-throughput genotyping of large numbers lines remains a key challenge in plant genetics, requiring geneticists and breeders to find balance between data quality the number genotyped under variety different existing technologies when resources are limited. In this work, we proposing new imputation pipeline (“HBimpute”) that can be used generate high-quality genomic from low read-depth whole-genome-sequence data. The idea is use haplotype blocks software HaploBlocker identify locally...

ABSTRACT Generations of farmer selection have produced a unique collection traditional maize varieties adapted to the environmental challenges central Mexican highlands. In addition agronomic and cultural value, highland represents good system for study local adaptation acquisition adaptive phenotypes under cultivation. this study, we characterized recombinant inbred line population derived from cross B73 reference variety Palomero Toluqueño. Evaluation over multiple years in lowland field...

Abstract Genetic variation is of crucial importance for selection and genetic improvement crops. Landraces are valuable sources diversity germplasm improvement, but quantitative traits efficient strategies their targeted utilization lacking. Here, we propose a genome-based strategy making native accessible with limited in elite germplasm. We generated ~ 1,000 doubled-haploid (DH) lines from three European maize landraces, pre-selected based on molecular phenotypic information. Using GWAS,...
