Hoyos Villegas, V.Polanía Perdomo, José A.Morales, Francisco JoséMiles, John W.Rao, Idupulapati M.[Phenoypic differences in adaptation to drought stress in Brachiaria grasses]Phenoypic differences in adaptation to drought stress in Brachiaria grasses

Background: Even though Plasmodium vivax has the widest worldwide distribution of the human malaria species and imposes a serious impact on global public health, the investigation of genetic diversity in this species has been limited in comparison to Plasmodium falciparum. Markers of genetic dive...

A total of 44 bean (Phaseolus vulgaris L.) genotypes was evaluated for disease reactions to bean golden mosaic virus (BGMV) by mechanical and whitefly inoculation under glasshouse and field conditions, respectively. Most of the genotypes reacted similarly under both screening conditions, with a f...

Bean dwarf mosaic geminivirus (BDMV) was shown to have a bipartite genome (DNA-A and DNA-B) from restriction map and sequence data comparisons of cloned DNAs. The nucleotide sequences of the infectious clones of DNA-A and DNA-B were determined. Computer analyses showed that the bipartite genome o...

The proliferation and rapid dissemination of whitefly-transmitted viruses of important food and industrial crops in Latin America, have been the consequence of drastic changes in traditional cropping systems. Some of the expanding non-traditional cash and export crops, such as soybean and several...

A selection study was conducted with 6 hybrid bean populations in 3 double groups, with low, intermediate, and high yield potential, at CIAT`s exptl. farm in Popayan (Cauca, Colombia), in a P-deficient soil with pH 4.5. These soil conditions allow for high disease incidence such as anthracnose (C...

En 1998 se inició una investigación para determinar la etiología a de dos enfermedades de aparente naturaleza viral, que afectan el cultivo de la palma africana de aceite en el suroccidente colombiano. La pre sencia de la mancha anular se registré por primera vez en 1985, en el municipio de Tum...

Se visitaron 11 departamentos productores de maracuyá (Passiflora edulis) en Colombia, donde se colectaron 338 muestras de plantas del frutal aparentemente afectadas por enfermedades virales. El análisis de estas muestras se realizó mediante técnicas de patogenicidad, microscopia electrónica, ser...

Observaciones al microscopio electrónico de extractos de plantas de pitahaya amarilla (Selenicereus megalanthus) afectada por un mosaico tenue, procedentes del municipio de Arbeláez, Cundinamarca, revelaron la presencia de partículas flexuosas de aspecto viral de aproximadamente 476 x 10 nm. Medi...
