“…Modified ouchterlony double diffusion test failed to differentiate the sorghum isolates from maize ones. These results refer to a strong similarity (had the same antigenic determinants) between them and similar with the results obtained by Rataj-Guranowska et al (1984) on Fusarium oxysporum f. sp. lupini.…”

In 2005, severe attack of sorghum leaf blight caused by Exserohilum turcicum was observed on grain sorghum G-15(Sorghum bicolar) and Sudan grass (Sorghum sudanense) adjacent to healthy maize plants in Sids Agricultural Research Station (SARS) of Upper Egypt, A.R.C. Therefore, field experiments were conducted in 2006, 2007 and 2008 to determine host specificity type of E. turcicum in SARS on a set of ten sorghum and maize varieties. Two E. turcicum isolates obtained from lesions of infected sorghum plants were tested for their virulence in the greenhouse on seedlings of the same set of varieties used in the field. Colony and conidial morphology, radial growth at four temperature and serological studies of these sorghum isolates were compared with two maize isolates. One colony type was clearly distinguishable between sorghum isolates from nature at SARS. Fungal colonies from sorghum were generally characterized as having dark olivaceous, determinate margin with scant appressed aerial hyphae. Meanwhile fungal colonies from maize had a determinate margin and profuse aerial hyphae about the center of a gray to green-white colony. Sids isolates of E. turcicum attacked only its own hosts, local grain sorghum and Sudan grass, under natural and artificial infections. Our results reveled that sorghum isolates had a fast radial growth in culture than maize isolates at 27°C. At the same time, there were considerable differences in conidial characters among isolates of E. turcicum from the two hosts although they were serologically identical. Conidia of sorghum isolates had a long length range and more septa than of maize isolates (66-145 µm, 6 and 40-92 µm, 4 septate respectively). Based on the occurrence of distinct fungal colony type of E. turcicum isolates from sorghum along with host-specificity, fungal isolates obtained from Sids were classified as forma specialis.

Fusarium oxysporum is the most economically important and commonly encountered species of Fusarium. This soil-borne fungus is known to harbour both pathogenic (plant, animal and human) and non-pathogenic strains. However, in its current concept F. oxysporum is a species complex consisting of numerous cryptic species. Identification and naming these cryptic species is complicated by multiple subspecific classification systems and the lack of living ex-type material to serve as basic reference point for phylogenetic inference. Therefore, to advance and stabilise the taxonomic position of F. oxysporum as a species and allow naming of the multiple cryptic species recognised in this species complex, an epitype is designated for F. oxysporum. Using multi-locus phylogenetic inference and subtle morphological differences with the newly established epitype of F. oxysporum as reference point, 15 cryptic taxa are resolved in this study and described as species.

Use of antigenic composition to differentiate among Rhizoctonia solani isolates from flax

et al. 2018

View full text Add to dashboard Cite

Rhizoctonia solani is an plant pathogenic fungus with a wide host range and worldwide distribution. Double diffusion technique was used to differentiate among Rhizoctonia solani isolates from flax. In this technique, antisera of isolate 23 (AG-2) and isolate 24 (AG-4) reacted against antigens of 24 isolates belonging to AG-2 and Ag-4. The antiserum of isolate 23 (AG-2) was insensitive to differentiate among the isolates of AG-2, while it was highly sensitive to differentiate among some isolates of AG-4. The antiserum of isolate 24 (AG-4) was highly sensitive as a serotaxonomic tool to differentiate among AG-2 and AG-4, while it was of limited value in differentiating among isolates of within each AG.
