Última Extent and structure of genetic diversity in a collection of the tropical multipurpose shrub legume Cratylia argentea (Desv.) O. Kuntze as revealed by RAPD markers Electron. J. Biotechnol. Andersson,Meike S; Schultze-Kraft,Rainer; Peters,Michael; Duque,Myriam C; Gallego,Gerardo. The tropical multipurpose shrub legume Cratylia argentea is well adapted to acid soils of low to medium fertility and has excellent drought-tolerance. Due to its high nutritive value it is particularly suited as forage for dry-season supplementation. A collection of 47 C. argentea accessions in a collection, derived from seed replicating of original accessions with differing geographic origin and morphological and agronomic characteristics was investigated using molecular markers (RAPD (random amplified polymorphic DNA)). Genetic diversity (H T = 0.145) in the collection was low, with 30% of differentiation among groups and high genetic similarity among accessions (GS = 0.805). Within-accession variability was high. One taxonomic mismatch and five possible... Tipo: Journal article Palavras-chave: Agroforestry; Molecular markers; MPT (multipurpose shrubs and trees); Tropics.

Mol. Biol. Alvarez,Alba; Fuentes,Jorge Luis; Puldón,Violeta; Gómez,Pedro Julio; Mora,Leonor; Duque,Miriam C.; Gallego,Gerardo; Tohme,Joe M.. 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 relationship for breeding purposes. Heterozygosity was analyzed at each microsatellite loci and for each genotype using 10 microsatellite primer pairs. Between varieties genetic relationship was estimated. The number of alleles per microsatellite loci was 4 to 8, averaging 6.6 alleles per locus. Higher heterozygosity (H) was found in traditional varieties (H TV = 0.72) than in improved varieties (H IV = 0.42), and 68% of the total microsatellite alleles were found...
