Specific Virulence

Five isolates of the bean rust fungus Uromyces appendiculatus were shown to be specifically virulent on bean genotypes of Andean origin. This specificity was demonstrated by the virulence of five pairs of isolates on a differential set of 30 Phaseolus vulgaris landraces. Each isolate pair was from a different country in the Americas and consisted of one Andean-specific isolate and one nonspecific isolate. Of the differential P. vulgaris landraces, 15 were of Middle American origin and 15 were of Andean origin. The Andean-specific rust isolates were highly virulent on Andean landraces but not on landraces of Middle American origin. Rust isolates with virulence to Middle American landraces were also generally virulent on Andean material; no truly Middle American-specific isolates were found. Random amplified polymorphic DNA (RAPD) analysis of the rust isolates also distinguished the two groups. Four of the Andean-specific rust isolates formed a distinct group compared to four of the nonspecific isolates. Two of the isolates, one from each of the two virulence groups, had intermediate RAPD banding patterns, suggesting that plasmagomy but not karyogamy occurred between isolates of the two groups.

Clear Differentiation

Populations of 90 Uromyces appendiculatus isolates were collected from throughout the Americas and evaluated for virulence on 19 standard bean rust differentials, and also on 12 landraces of Phaseolus vulgaris from South and Central America. The landrace differentials represented geographical centers of bean domestication. Three groups were observed. Two groups were isolates from centers of bean domestication and a third heterogeneous group comprised isolates from countries in South and Central America. Molecular analysis using random amplified polymorphic DNA-polymerase chain reaction (RAPD-PCR) was also conducted on these isolates. Cluster analysis of the molecular profiles showed three groups that corresponded to those obtained by virulence tests. These results show a clear differentiation of the pathogen population along similar lines as its host and suggest parallel evolution in the bean rust pathosystem.

The North

The varieties (64) of common beans (Phaseolus vulgaris L.) were evaluated for resistance to bean rust in the Velasco zone, at the north of the Holguín province, Cuba. The evaluation was made 60 days after sowing by determining the degree of attack using a scale as well as estimating the number of pu stules per leaf and no remarkable differences between both methods were found. The character of the pustules was also determined by measuring their diameters with regard to three categories large (more than 0.5 mm) middling (between 0.3 and 0.5 mm) and small (less than 0.3 mm) and the presence or lack of chlorotic halo surrounding the pustules as well. The cultivars that resulted less attacked by the bean rust were Guira-35, XAN-43, Revolución-79, M-112, Rosas, BAT-202, Tazumal, Huetar, Bolita-42, BAT-1281, BAT-1274, BAT-1280, PV-555, BAT 1275, Engañador, Guamá- 23, MCD-254, Chevere, XAN-93, XAN-147, NAG-20, NAG-55, RAB-30 and CC 25-9-S (R), all of which showed an average equal or inferior to 10 pustules per leaf, being these ones generally smaller and without any chlorosis.

Mesophyll Cells

The morphology of intercellular and intracellular hyphae derived from basidiospores of Uromyces appendiculatus var. appendiculatus is described. Light and electron microscopic observations of the bean rust fungus were made on susceptible leaves of Phaseolus vulgaris from 3 to 10 days after inoculation. Following egress from invaded epidermal and palisade parenchyma cells, the fungus grew rapidly and developed extensive intercellular mycelium. An amorphous to fibrillar extracellular matrix was deposited between fungal and host cell walls. Intercellular hyphae grew closely appressed to the mesophyll cells and penetrated them to form intracellular hyphae from either a terminal or nonterminal mother cell. Intracellular hyphae were fingerlike, sometimes septate, and generally remained terminal in the invaded mesophyll cell. Occasionally the fungus exited the cell to become an intercellular hypha or an intracellular hypha in an adjacent host cell. The plant rarely exhibited a resistantlike reaction at sites of penetration into mesophyll cells.

Bean rust caused by Uromyces appendiculatus (Pers.) Unger is an important disease in common bean (Phaseolus vulgaris L.) worldwide. To our knowledge this is the first report of a new race of U. appendiculatus (19-63) in Puerto Rico and in the western hemisphere. Accepted for publication 4 February 2009. Published 25 March 2009.

Bean rust (Uromyces appendiculatus) reached epidemic proportions in North Dakota and Minnesota from 1993 to 1996. Although U. appendiculatus is a macrocyclic autoecious rust, neither pycnia nor aecia have been observed in commercial dry bean (Phaseolus vulgaris) in North Dakota fields. The source of initial inoculum is not clearly understood. This study determined the potential for urediniospore survival overwinter. Uredia-bearing bean leaves from artificially inoculated greenhouse-grown plants were kept outside near a field from November to May from 1990 to 1996. Based on bioassays urediniospores survived overwinter, but viability declined over time. Overwinter survival indicates urediniospores may function as initial inoculum.

A ferrugem do feijoeiro comum (Phaseolus vulgaris), incitada pelo fungo Uromyces appendiculatus, é uma das mais importantes doenças que afetam essa cultura. Trabalhos anteriores demonstraram a ampla variabilidade patogênica de U. appendiculatus no Brasil. No entanto, o uso de distintos grupos de cultivares diferenciadoras em tais trabalhos dificulta a análise comparativa e a identificação de fontes de resistência de amplo espectro. Assim, os objetivos deste trabalho foram: 1) caracterizar sete isolados de U. appendiculatus, coletados em diferentes regiões do estado de Minas Gerais, frente às 19 cultivares diferenciadoras para ferrugem, adotadas no "The Bean Rust Workshop", realizado em 1983, em Porto Rico, e 2) comparar os padrões de resistência/suscetibilidade obtidos, com aqueles apresentados frente a patótipos isolados nos estados de Santa Catarina, Rio Grande do Sul e Goiás, visando identificar fontes de resistência de amplo espectro. Os sete isolados coletados em Minas Gerais foram classificados com sete patótipos distintos. As cultivares diferenciadoras com os maiores espectros de resistência foram 'Redlands Pioneer', 'California Small White 643', 'Brown Beauty', 'AxS 37' e 'Compuesto Negro Chimaltenango'. Portanto, apesar da exclusão das cultivares California Small White 643, AxS 37 e Brown Beauty da nova série diferenciadora internacional proposta em 2002, na África do Sul, recomenda-se adicionar estas cultivares nas futuras caracterizações de patótipos a serem realizadas no Brasil, como um modo de monitorar a variabilidade patogênica de populações de U. appendiculatus nas regiões produtoras.
