Preempting plantparasitic nematode losses on banana in Africa: which species do we target?

Autor: Coyne, D.L.

Plant-parasitic nematodes cause serious damage on banana in Africa. Affected plants are less able to access nutrients and water, leading to yield losses, particularly under nutrient- and water-stressed conditions. Heavily affected plants often topple, with consequent total loss of bunches, while ...

Pathogenic variation of colletotrichum lindemuthianum causing anthracnose of beans (phaseolus vulgaris) in Uganda

Autor: Kiryowa, Moses J. Ebinu, Aston Kyaligonza, Vincent Nkalubo, Stanley T. Paparu, Pamela Mukankusi, Clare Mugisha Tukamuhabwa, Phinehas

Colletotrichum lindemuthianum is a highly variable pathogen of common beans that easily overcomes resistance in cultivars bred with single-gene resistance. To determine pathogenic variability of the pathogen in Uganda, samples of common bean tissues with anthracnose symptoms were collected in eig...

Genetic diversity in South American Colletotrichum gloeosporioides isolates from Stylosanthes guianensis, a tropical forage legume

Autor: Kelemu, Segenet Skinner, DZ Badel, JL Moreno, CX Rodríguez, M.X. Fernandes, C.D. Charchar, Maria José Chakraborty, S.

The degree of genetic diversity of 127 Colletotrichum gloeosporioides isolates from Stylosanthes guianensis genotypes in South America was measured at the molecular level by random amplified polymorphic DNA (RAPD) with nine arbitrary primers of 10 bases, and by restriction fragment length polymor...

Characterization of pathotypes among isolates of Xanthomonas axonopodis pv. manihotis in Colombia

Autor: Restrepo, S. Duque E., Myriam Cristina Verdier, Valérie

Cassava bacterial blight, caused by Xanthomonas axonopodis pv. manihotis (Xam) is a destructive disease occurring in most cassava growing-areas. Although Colombian isolates of Xam differ in DNA polymorphism and pathogenicity, no suitable host differentials have been identified to demonstrate phys...

Pathogenic variation of Mycosphaerella species infecting banana and plantain in Nigeria

Autor: Zandjanakou-Tachin, M. Ojiambo, P. Vroh Bi, Irie Tenkouano, A. Gumedzoe, Y.M. Bandyopadhyay, Ranajit

Mycosphaerella species that cause the ‘Sigatoka disease complex’ account for significant yield losses in banana and plantain worldwide. Disease surveys were conducted in the humid forest (HF) and derived savanna (DS) agroecological zones from 2004 to 2006 to determine the distribution of the dise...

Genetic diversity of Colletotrichum gloeosporioides in Nigeria using amplified fragment length polymorphismA (AFLP) markers

Autor: Aduramigba-Modupe, A.O. Asiedu, Robert Odebode, C.A. Owolade, F.

Colletotrichum gloeosporioides is the causal agent of yam anthracnose disease in Nigeria. Differential cultivars and amplified fragment length polymorphic DNA markers were used to assess the extent of genetic diversity among 39 isolates of the pathogen. Fourteen (14) pathotypes of the pathogen we...

Inheritance and characterization of angular leaf spot resistance gene present in common bean accession G 10474 and identification of an AFLP marker linked to the resistance gene

Autor: Mahuku, George S. Montoya, C Henriquez Naranjo, MA Jara, Carlos E. Terán Santofimio, Henry Beebe, Stephen E.

Angular leaf spot (ALS), caused by the fungus Phaeoisariopsis griseola (Sacc.) Ferr., is one of the most important diseases of common bean (Phaseolus vulgaris L.) in tropical and subtropical bean producing areas. The common bean accession G 10474 has been widely resistant to P. griseola, includin...
