“…Gerlach and Nirenberg (1982) and Nelson et al (1983) described the colony appearance of F. oxysporum on PDA as highly variable. Indeed, peach and violet colony colors, observed in the majority of isolates were consistent with the description of Booth (1971). Morphological studies showed Microconidia with zero to one septate; oval or cylindrical ( Figure 1A), produced on Disease incidence (%) = ∑(scale ×number of plants infected ) highest scale × total number of plants × 100 short monophialides ( Figure 1B) or in false heads ( Figure 1C).…”

Fusarium oxysporum is an ubiquitous soil-borne fungus, having a high genetic and ecological diversity with the potential to cause diseases of many crop species of economic interest. Indeed, some strains of F. oxysporum known as pathogens generate common diseases such as wilting, root and crown rot on host plants. Two formae speciales are confined to the tomato: F. oxysporum f.sp. lycopersici (FOL) causing Fusarium wilt, while F. oxysporum f.sp. radicis-lycopersici (FORL) causes Fusarium crown and root rot. The study include 27 strains isolated from the stems, crown and roots of infected tomato plants; to confirm the identity of the fungus, the isolates were identified using analysis based on morphological criteria and sequencing of the translation elongation factor 1-alpha (TEF) gene using ef1 and ef2 primers. Twenty three strains belonged to F. oxysporum, three strains to Fusarium solani, and one strain to Fusarium redolens. Tomato seedlings were tested to confirm the pathogenicity of the isolates tested. Pathogenicity test confirmed that twenty two F. oxysporum isolates were pathogenic on tomato and produced crown and root rot typical of F. oxysporum f.sp. radicis-lycopersici forma specialis, while one strain initially identified as F. oxysporum did not induce disease symptoms and is considered as non-pathogenic. Additionally, no symptoms of Fusarium wilt were observed at all; therefore no strains can be affiliated to F. oxysporum f.sp. lycopersici forma specialis.

“…It is cosmopolitan with respect to climate tolerance, and has been isolated from hosts as diverse as legumes, conifers and carnations (Booth, 1971). Inoculum in crop debris and soils may lead to seedling blight and foot rot.…”

“…Crop debris and stem base lesions may also act as a source of inoculum for the infection of ears at flowering via the splash dispersal of spores, leading to ear blight which, when severe, can cause considerable loss of yield and grain quality (Parry et al, 1995). F. avenaceum is one of the four Fusarium species most commonly isolated from ears of small grain cereals showing symptoms of fusarium ear blight (Parry et al, 1995), and although it is generally thought less pathogenic than F. culmorum and F. graminearum it has been regarded as a serious wheat pathogen in Russia and India (Booth, 1971). It has also been reported to be an aggressive pathogen of wheat in glasshouse trials (Parry et al, 1985).…”

Refinement of PCR‐detection of Fusarium avenaceum and evidence from DNA marker studies for phenetic relatedness to Fusarium tricinctum

Existing PCR-based assays for the detection of the cereal pathogen Fusarium avenaceum were found to cross-react with F. tricinctum. An investigation into the phenetic relationship between these two species using two different marker systems revealed a close relationship between them despite their being from separate taxonomic sections. Whilst RFLP differences in the ITS regions surrounding the nuclear 5·8 S rDNA were insufficient to discriminate between isolates of the two species, they were clearly differentiated by RAPD profiling. RAPD fragments from F. avenaceum isolates were screened for hybridization to F. tricinctum DNA on Southern blots. One of 12 selected RAPD fragments showed no hybridization to genomic DNA from F. tricinctum. This fragment was cloned and sequenced, and the sequence obtained was used to design PCR primers. The primers were found to be specific for F. avenaceum, with no cross-reactions obtained with F. tricinctum or any other wheat pathogen assayed. The primers were able to differentiate between the two species in infected plant material, in contrast to the earlier assays.

Genotypic diversity in a South African population of the pitch canker fungus Fusarium subglutinans f.sp. pini

et al. 1997

View full text Add to dashboard Cite

The genotypic diversity in a South African population of Fusarium subglutinans f.sp. pini (F.s. pini) was determined, based on the number of vegetative compatibility groups (VCGs). Isolates of F.s. pini from South Africa (69), California (five) and Florida (19) were included in the study. The nit1 (or nit3) and NitM mutants were selected as chlorate resistant sectors and paired on minimal medium. The South African isolates of F.s. pini were assigned to 23 different VCGs. No heterokaryons formed between isolates from South Africa, California and Florida. The high degree of genotypic diversity in the South African population of F.s. pini is probably due to some level of sexual reproduction in the population.
