Gymnoconia nitens (Schwein.) Kern & H. W. Thurston consists of two forms that cause orange rust of Rubus . The teliospores of both of these forms are morphologically identical to aeciospores, but upon germination form promycelia that give rise to eit

Orange rust of Rubus is an interesting disease because of the fact that it can be caused by three different rust fungi that produce virtually identical symptoms. One is Gymnoconia peckiana (Howe in Peck) Trotter, which is a demicyclic species, while

Basidia of the plant-pathogenic fungus Exobasidium camelliae var. gracilis Shirai became exposed on the abaxial side of an infected leaf of Camellia sasanqua Thunb. following the sloughing of the undersurface of the leaf. Basidia were formed in treme

Scanning and transmission electron microscopy were used to examine sporodochium and conidium development in Epicoccum nigrum Link. Each sporodochium, a slightly raised mass of hyphae consisting of a pseudoparenchymous stroma covered with muriform con

A combination of light, scanning, and transmission electron microscopy was used to examine teliospores and teliospore germination in the rust fungus Coleosporium ipomoeae (Schw.) Burrill, a parasite of the wild morning glory Ipomoea coccinea L. Telia

Transmission electron microscopy of high‐pressure frozen/freeze‐substituted samples was used to study urediniospore development in Coleosporium ipomoeae in leaves of Ipomoea coccinea. The urediniospores of this species are morphologically identic

Transmission electron microscopy was used to examine the host-pathogen interface in Arabidopsis thaliana (L.) Heynh. leaves infected by the biotrophic downy mildew pathogen Hyaloperonospora parasitica (Pers.:Fr.) Con- stant. Both conventionally fixed

This article reports on the use of high pressure freezing followed by freeze substitution (HPF/FS) to study ultrastructural details of host–pathogen interactions in fungal diseases of plants. The specific host–pathogen systems discussed here incl

Both conventional chemical fixation and high pressure freezing followed by freeze substitution (HPF/FS) were used to prepare zoosporangia of the oomycete Albugo ipomoeae-panduratae inside infected host leaves for study with transmission electron micr
