Quantitative trait locus mapping reveals regions of the maize genome controlling root system architecture.
The quest to determine the genetic basis of root system architecture (RSA) has been greatly facilitated by recent developments in root phenotyping techniques. Methods that are accurate, high throughput, and control for environmental factors are especially attractive for quantitative trait locus mapping. Here, we describe the adaptation of a nondestructive in vivo gel-based root imaging platform...
متن کاملDevelopment of a genomic microsatellite library in perennial ryegrass (Lolium perenne) and its use in trait mapping.
BACKGROUND AND AIMS Perennial ryegrass (Lolium perenne) is one of the key forage and amenity grasses throughout the world. In the UK it accounts for 70 % of all agricultural land use with an estimated farm gate value of 6 billion pounds per annum. However, in terms of the genetic resources available, L. perenne has lagged behind other major crops in Poaceae. The aim of this project was therefor...
متن کاملAdvances in Quantitative Trait Locus Mapping
The mapping of loci underlying variation in quantitative traits is proving to be a powerful tool in genetic studies of animals and other organisms. Quantitative trait locus (QTL) mapping in crosses between genetically diverse lines has shown the presence of many QTL, as similarly have studies within livestock populations. Although much remains to be done with this type of analysis, higher resol...
متن کاملMapping of genomic regions (quantitative trait loci) controlling production and quality in industrial cultures of the edible basidiomycete Pleurotus ostreatus.
Industrial production of the edible basidiomycete Pleurotus ostreatus (oyster mushroom) is based on a solid fermentation process in which a limited number of selected strains are used. Optimization of industrial mushroom production depends on improving the culture process and breeding new strains with higher yields and productivities. Traditionally, fungal breeding has been carried out by an em...
متن کامل3D phenotyping and quantitative trait locus mapping identify core regions of the rice genome controlling root architecture.
Identification of genes that control root system architecture in crop plants requires innovations that enable high-throughput and accurate measurements of root system architecture through time. We demonstrate the ability of a semiautomated 3D in vivo imaging and digital phenotyping pipeline to interrogate the quantitative genetic basis of root system growth in a rice biparental mapping populati...
