Fuentes, JLCorrea Victoria, Fernando J.Escobar R, F.Prado Patiño, G.A.Aricapa, María GirlenaDuque E., Myriam CristinaTohme, Joseph M.[Tagging Pi-l(t) gene for blast resistance in rice via linkage to microsatellite markers]Tagging Pi-l(t) gene for blast resistance in rice via linkage to microsatellite markers
González Torres, Rosa InésGaitán Solís, ElianaDuque E., Myriam CristinaToro Chica, OrlandoDebouck, Daniel G.Tohme, Joseph M.[Estimation of gene flow on Phaseolus vulgaris L. using molecular markers : Microsatellites and polymorphisms at chloroplast DNA]Estimation of gene flow on Phaseolus vulgaris L. using molecular markers : Microsatellites and polymorphisms at chloroplast DNA

The present work was conducted to identify microsatellite markers linked to the rice blast resistance gene Pi-1(t) for a marker-assisted selection program. Twenty-four primer pairs corresponding to 19 microsatellite loci were selected from the Gramene database (www. gramene.org) considering their...

A total of 150 microsatellite markers developed for common bean (Phaseolus vulgaris L.) were tested for parental polymorphism and used to determine the positions of 100 genetic loci on an integrated genetic map of the species. The value of these single-copy markers was evident in their ability to...

To facilitate the creation of easily comparable, low-resolution genetic maps with evenly distributed markers in rice (Oryza sativa L.), we conceived of and developed a Universal Core Genetic Map (UCGM). With this aim, we derived a set of 165 anchors, representing clusters of three microsatellite ...

International rice export markets are increasing demands for rapid improvements in grain quality characteristics. The African rice Oryza glaberrima is a new potential source of genes that will enhance the eating, cooking, and milling properties of the rice grain. The objective of this research wa...


Aluko, GKMartínez Racines, César PompilioTohme, Joseph M.Castaño Rodríguez, C.Bergman, C.Oard, JH[QTL mapping of grain quality traits from the interespecific cross Oryza sativa x O. glaberrima]QTL mapping of grain quality traits from the interespecific cross Oryza sativa x O. glaberrima

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 ...

The cassava core collection was selected to represent, with minimum repetitiveness, the potential genetic diversity of the crop. The core (630 accessions) was chosen from the base collection (over 5500 accessions) on the basis of diversity of origin (country and geographic), morphology, isozyme p...


Chavarriaga Aguirre, PaulMaya, M.M.Tohme, Joseph M.Duque E., Myriam CristinaIglesias, C.A.Bonierbale, Merideth W.Kresovich, SKochert, G[Using microsatellites, isozymes and AFLPs to evaluate genetic diversity and redundancy in the cassava core collection and to assess the usefulness of DNA-BASED markers to maintain germplasm collections]Using microsatellites, isozymes and AFLPs to evaluate genetic diversity and redundancy in the cassava core collection and to assess the usefulness of DNA-BASED markers to maintain germplasm collections

The extent and structure of the genetic variability of traditional varieties of cassava (Manihot esculenta Crantz) have been little documented, despite considerable evidence for this crop's great varietal diversity in traditional agroecosystems. We used microsatellite markers to assess the geneti...

Microsatellite polymorphism was studied in a sample of 39 traditional rice (Oryza sativa L.) varieties and 11 improved varieties widely planted in Cuba. The study was aimed at assessing the extent of genetic variation in traditional and improved varieties and to establish their genetic relationsh...
