Autor: Lartigue, C. Valverde Timana, Y. Labroussaa, F. Schieck, Elise G. Liljander, Anne M. Sacchini, Flavio Posthaus, H. Batailler, B. Sirand-Pugnet, P. Vashee, S. Jores, Joerg Blanchard, Alain

Mycoplasma species are responsible for several economically significant livestock diseases for which there is a need for new and improved vaccines. Most of the existing mycoplasma vaccines are attenuated strains that have been empirically obtained by serial passages or by chemical mutagenesis. Th...

Genetic variability within Phaeoisariopsis griseola from Central America and its implications for resistance breeding of common bean

Autor: Mahuku, George S. Jara, Carlos E. Cuasquer, Juan B. Castellanos, G.

The genetic and virulence variability of 112 isolates of Phaeoisariopsis griseola, collected from various locations in Central America, were studied using seven random amplified polymorphic DNA (RAPD) primers and 12 common-bean differential genotypes. Broad molecular diversity (H = 0·92) among is...

In planta gene expression analysis of Xanthomonas oryzae pathovar oryzae, African strain MAI1

Autor: Soto Suárez, M. Bernal, D. González, C. Szurek, B Guyot, R Tohme, Joseph M. Verdier, Valérie

Background: Bacterial leaf blight causes significant yield losses in rice crops throughout Asia and Africa. Although both the Asian and African strains of the pathogen, Xanthomonas oryzae pv. oryzae (Xoo), induce similar symptoms, they are nevertheless genetically different, with the African stra...

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...

DNA polymorphism and variation in virulence of Xanthomonas axonopodis pv. manihotis (Xam), the causal agent of cassava bacterial blight, were studied within a pathogen population from Venezuela. Collections were made in several fields at different sites within an edaphoclimatic zone where cassava...

Pathogenic variation in Xanthonomas campestris pv. phaseoli, the causal agent of common bacterial blight in Phaseolus beans

Autor: Opio, A.F. Allen, David J. Teri, J.M.

A total of 93 isolates of Xanthomonas campestris pv. phaseoli was collected from five countries over a wide range of altitude (500 2320 m above sea level) in eastern Africa. Collections were made from a range of cultivars of the common bean (Phaseolus vulgaris), including known sources of resista...

Pathogenic variation in, sources of, and breeding for resistance to Phaeoisariopsis griseola causing angular leaf spot in common bean

Autor: Pastor Corrales, Marcial A. Jara, Carlos E. Singh, Shree P.

If we are to breed common bean (Phaseolus vulgaris L.) for durable resistance to diseases, we must understand pathogenic variation and find sources of resistance. Our first objective was to determine the patterns of pathogenic variation found among isolates of Phaeoisariopsis griseola (PG), the f...

Pathogenic variability in Pyricularia grisea at a rice blast "hot spot" breeding site in Eastern Colombia

Autor: Correa Victoria, Fernando J. Zeigler, Robert S.

Forty-five international races of Pyricularia grisea, representing all nine race groups, were identified in a "hot spot" breeding site (Santa Rosa) in Colombia, with the largest number included in the IA group. The international race system did not fully describe the virulence spectrum of the iso...
