Polysaccharides from Hemileia vastatrix uredospores

Experimental Mycology, 1983
Abstract The polysaccharidic fractions isolated from Hemileia vastatrix uredospores by alkali treatment, expressed as a percentage of the initial uredospore weight, gave the following yields: 1 M NaOH soluble at 22°C (7.1); 1 M NaOH soluble at 60°C (5.0); and insoluble residue (7.6).

Abnormal development of uredia in Hemileia vastatrix

Transactions of the British Mycological Society, 1965
In Hemileia vastatrix Berk. & Br. the only type of uredium so far known is typically superstomal. Rare occurrences of subepidermal uredia and sori developed inside the intercellular spaces of the spongy parenchyma, intermingled with the typical hypophyllous, superstomal sori are described.

Sensitization to the fungus Hemileia vastatrix (coffee leaf rust)

Allergy, 2001
Background: The aim of the present study was to determine the existence of sensitization to the fungus Hemileia vastatrix (coffee leaf rust) in a sample of the Brazilian population. This fungus attacks coffee plantations, and in some regions of Brazil the concentration of its spores in the air can be very high.

A New type of Nuclear Life Cycle in Hemileia Vastatrix

Mycologia, 1967
Hemileia vastatrix1 is the cause of rust disease of coffee, and there have been many investigations of its life cycle. This rust is characterized by the formation of non-resting teliospores which germinate in situ and produce sporidia, which, however, are unable to reinfect coffee, which suggests that they are non-functional2–4.

Genetic diversity inHemileia vastatrixbased on RAPD markers

Mycologia, 2005
Random amplified polymorphic DNA (RAPD) was used to assess the genetic structure of Hemileia vastatrix populations. Forty-five rust isolates with different virulence spectra and from different hosts and geographical regions were analyzed. Out of 45 bands, generated with three RAPD primers, 35 (78%) were polymorphic and scored as molecular markers ...

Análise de elementos transponíveis em Hemileia vastatrix e Coffea spp.

2023
A ferrugem do cafeeiro é causada pelo fungo Hemileia vastatrix Berk. & Broome, um parasita obrigatório que infecta folhas de plantas do gênero botânico Coffea. Entre as espécies cultivadas deste gênero, Coffea arabica é a mais suscetível. A desfolha precoce pode levar à morte de ramos, seguido de perdas da produtividade no ano subsequente. Os danos
