Glacial refuge areas are expected to harbor a large fraction of the intraspecific biodiversity of the temperate biota. To test this hypothesis, we studied chloroplast DNA variation in 22 widespread European trees and shrubs sampled in the same forests. Most species had genetically divergent populations in Mediterranean regions, especially those with low(More)
The genus Phyllanthus consists of more than 1000 species, of which many are used as traditional medicines. The plant extracts have been used since ancient times, for treating hypertension, diabetes, hepatic, urinary, and sexual disorders, and other common ailments. Modern day scientific investigations have now confirmed pharmacognostic properties of(More)
This paper describes findings in the characterization of 300 accessions in a collection of common beans (Phaseolus vulgaris L.) in Honduras. The plant material was collected from 1990 to 1994 (4 years before the damaging Mitch Hurricane) covering most of the Departments of the country and kept at the Escuela Agrícola Panamericana Zamorano. Thirty-two(More)
Evaluation of chloroplast DNA (cpDNA) diversity in wild relatives of crop brassicas is important for characterization of cytoplasm and also for population genetics/phylogeographic analyses. The former is useful for breeding programs involving wide hybridization and synthesis of alloplasmic lines, while the latter is important for formulating conservation(More)
Phyllanthus amarus and Phyllanthus fraternus are important ethnomedicinal herbs used as traditional medicines in many parts of the world. The increasing popularity of these green medicines and almost no studies on structuring of genetic diversity in these herbs, led to this investigation. Keeping this in view, our main objective was to analyze the(More)
