Quantitative Trait Loci for Root Architecture Traits Correlated with Phosphorus Acquisition in Common Bean
Low soil P availability is a primary constraint to common bean (Phaseolus vulgaris L.) production in Latin America and Africa. Substantial genotypic variation in bean adaptation to low phosphorus (LP) availability has been linked with root traits that enhance the efficiency of soil foraging. The objectives of this study were to identify quantitative trait loci (QTLs) for P accumulation and asso...
متن کاملQuantitative Trait Loci Associated with Drought Tolerance in Common Bean
Drought stress is the major limitation of common bean (Phaseolus vulgaris L.) grown in subsistence farming systems worldwide. The objective of this study was to use single nucleotide polymorphism (SNP) markers from the BARCBean6K_3 Beadchip to identify quantitative trait loci (QTL) associated with traits related to drought tolerance in common bean. An intergene pool recombinant inbred line (RIL...
متن کاملPhosphorus stress in common bean: root transcript and metabolic responses.
Phosphorus (P) is an essential element for plant growth. Crop production of common bean (Phaseolus vulgaris), the most important legume for human consumption, is often limited by low P in the soil. Functional genomics were used to investigate global gene expression and metabolic responses of bean plants grown under P-deficient and P-sufficient conditions. P-deficient plants showed enhanced root...
متن کاملCombining Ability and Gene Action in Sunflower Using Line*Tester Method
In order to analyze general and specific combining abilities and gene effects in sunflower for some agronomic traits, five CMS lines and four restorer lines (tester) were crossed in a line × tester scheme. Hybrids were evaluated in a randomized complete block design with three replications in the Agriculture Research Station, University of Tabriz, in 2009 and 2010 growing seasons. Plant height,...
متن کاملMonitoring gene flow between wild relatives and landraces of common bean in Costa Rica
Introduction Gene flow is the spread of genetic material among populations and may constitute an important evolutionary force to create genetic variability. We study possible cases of gene flow in accessions of Phaseolus vulgaris L. collected in the Central Valley of Costa Rica (Araya et al. 2001), The present study aims to establish the movement of genes in the complex wild/weed/cultivated of ...
