Gálvez E., Guillermo E.Morales, Francisco José[Whitefly-transmitted viruses]Whitefly-transmitted viruses

One group of bean diseases with characteristic virus symptoms is the mosaic group, frequently associated with leaf and plant malformations and green and yellow stippling. Insect vectors belong to the families Chrysomelidae, Coccinelidae, and Meloidae. This group of virus contains the bean souther...

Un grupo de enfermedades del frijol con sintomas caracteristicos de los producidos por los virus es el de los mosaicos, frecuentemente asociados con deformaciones de las hojas y de las plantas y moteado verde o amarillo. Los insectos vectores son de las familias Chrysomelidae, Coccinelidae y Melo...

Bean crops are attacked by several viruses transmitted by insects among which are: (1) beet curly top virus (Circulifer tenellus); the best control measure is the utilization of resistant var.; (2) the tobacco yellow dwarf virus (Orosius argentatus); (3) the tomato spotted wilt virus, which is tr...

El cultivo del frijol es atacado por varios virus transmitidos por insectos, entre los cuales estan: 1) el virus del apice rizado de la remolacha (Circulifer tenellus); la mejor medida de control es el uso de var. resistentes; 2) la muerte de verano del frijol (Orosius argentatus); 3) el virus de...

Seeds provide an efficient method for disseminating pathogenic organisms to different locations; more than 50 percent of the major bean diseases are seed borne. Mechanical damage, which may occur during harvesting, threshing and/or planting can affect seed viability, germination, and result in co...

La semilla constituye un metodo eficiente de diseminacion de organismos fitopatogenos a diversas localidades; mas de 50 por ciento de las principales enfermedades del frijol son transmitidas por la semilla. El dano mecanico que ocurre durante la cosecha, trilla y/o siembra tambien puede afectar l...

The main insect pests and diseases associated with Brachiaria pastures are considered, with emphasis on spittlebugs, the most damaging pests in tropical America. Outbreaks of the polyphagous burrowing bugs of the genus Scaptocoris, both in Brazil and Colombia, are of concern. Other pests discusse...

Se determinó la secuencia completa del ARN genómico del Virus del mosaico común del fríjol (Bean common mosaic virus) cepa NL4 (BCMV-NL4). El genoma viral consta de 10037 nucleótidos excluyendo la cola de poli (A) y contiene una trama de lectura abierta (ORF) de 9666 nucleótidos que codifica una ...

Bean golden yellow mosaic virus (BGYMV) is a whitefly-transmitted geminivirus of the Begomovirus family that causes important yield losses to common beans grown in tropical and sub-tropical countries of Latin America and the Caribbean. A major resistance gene that has been widely deployed in this...

Eighty-three F2-derived F8 recombinant inbred lines (RILs) randomly selected from a population (TY 8419) of two common bean genotypes (Pinto UI 114 x ICA Pijao), the two parents, and a control cultivar (Topcrop) were screened for their reaction to bean golden mosaic virus (BGMV) under glasshouse ...

Bean golden mosaic geminivirus (BGMV) causes major losses on beans (Phaseolus vulgaris) in the tropical and subtropical Americas and the Caribbean Basin. Infectious DNA-A and -B components of BGMV isolates from the Dominican Republic (BGMV-DR) and Guatemala (BGMV-GA) were sequenced, and their gen...
