Uromyces appendiculatus in Honduras: Pathogen Diversity and Host Resistance Screening
Acevedo, M., Steadman, J. R., and Rosas, J. C. 2013. Uromyces appendiculatus in Honduras: Pathogen diversity and host resistance screening. Plant Dis. 97:652-661. Bean rust, caused by the fungus Uromyces appendiculatus, is a major constraint for common bean production worldwide. Virulence of U. appendiculatus collected from wild and cultivated Phaseolus spp. was examined in 28 locations across ...
متن کاملActivation of Teliospore Germination in Uromyces appendiculatus var. appendiculatus. I. Aging and Temperature
The effects of aging and temperature on teliospore germination in Uromyces appendiculatus var. appendiculatus were studied. 1. Indoor storage was good at ~ 4 QC in the dirk. Under these conditions spores remained dormant for ~ 9 mo, but thereafter germination gradually increased to a maximum (~ 63 %) after 36 moo Spores .9tored outdoors showed a marked increase in germination after ~ 4 mo and r...
متن کاملCytology of Teliospore Germination and Basidiospore Formation in Uromyces appendiculatus
The cytology of teliospore germination and basidiospore formation in Urornyces appendiculatus vat. appendieulatus was characterized with light and fluoroscence microscopy. Meiosis of the diploid nucleus occurred in the metabasidium. The four haploid daughter nuclei migrated into the basidiospore initials where they underwent a post meiotic mitosis. Each basidiospore was delimited from the meata...
متن کاملCytology of basidiospore germination, penetration, and early colonization of Phaseolus vulgaris by Uromyces appendiculatus var. appendiculatus
GOLD, R. E., and K. MENDGEN. 1984. Cytology of basidiospore germination, penetration, and early colonization of Phaseolus vulgaris by Uromyces appendiculatus var. appendiculatus. Can. J. Bot. 62: 1989-2002. Cytological studies were done on a compatible interaction between Phaseolu.\ vulgaris and Uromyces appendiculatus var. appendiculatus. The cytoplasm of germinated basidiospores contained num...
متن کاملActivation of Teliospore Germination in Uromyces appendiculatus var. appendiculatus. II. Light and Host Volatiles
The effects of light and host volatiles on teliospore germination in Uromyces appendiculatus var. appendiculatus were studied. I. Light intensities ranging 15-26000 lux supported teliospore germination and basidiospore formation. The optimum light intensity was 17000 lux under the described conditions. Light-dark alternation was necessary for teliosp.ore germination: no germination occurred und...
