“…apii, asparagi, batatas pisi, vasinfectum, and others) have been shown to cross-infect the hosts of other formae speciales; isolates received as a specific forma specialis might in such cases also be classifiable as another forma specialis, in particular in the case of F. oxysporum f. sp. vasinfectum (Armstrong and Armstrong, 1975;Davis et al, 2006). Isolates belonging to different formae speciales and sharing their STs should be tested systematically for cross-pathogenicity in future investigations.…”

Cumagun C.J.R., Aguirre J.A., Relevante C.A., Balatero C.H. (2010): Pathogenicity and aggressiveness of Fusarium oxysporum Schl. in bottle gourd and bitter gourd. Plant Protect. Sci., 46: 51-58.Fusarium oxysporum is responsible for a large range of diseases on economically important crops such as bitter gourd and bottle gourd. Pathogenicity and aggressiveness of F. oxysporum in bitter gourd and bottle gourd isolated from two breeding stations of East-West Company in the Philippines namely San Ildefonso, Bulacan and Lipa, Batangas were tested. Eleven F. oxysporum isolates from bitter gourd and 12 isolates from bottle gourd were inoculated on 7-day and 1-month-old bitter gourd and bottle gourd plants in the greenhouse. All F. oxysporum isolates from bitter gourd were pathogenic on 7-day-old and 1-month-old bitter gourd and nine out of 12 isolates from bottle gourd were pathogenic on bottle gourd. Three isolates from the infested soil were non-pathogenic on bottle gourd. There was a significant difference in aggressiveness of the isolates on their natural hosts (P ≤ 0.05). There also was a significant difference in the aggressiveness of isolates pathogenic on bitter gourd from Batangas and Bulacan (P ≤ 0.05) but isolates from Batangas and Bulacan had similar aggressiveness as bottle gourd (P ≥ 0.05). Aggressiveness of F. oxysporum on 7-day-old bitter gourd and bottle gourd was significantly different compared to those on 1-month-old plants, demonstrating an effect of the host age onaggressiveness. Correlations between aggressiveness of F. oxysporum isolates on 7-day-old and 1-month-old bitter gourd and bottle gourd were moderate (r = 0.63, 0.78). Out of 12 isolates from bottle gourd, only one isolate was pathogenic on 7-day-old bitter gourd. Four of the isolates from bitter gourd were pathogenic on 7-day-old bottle gourd but not on 1-month-old bottle gourd. No cross infection was observed on mature plants.

“…This species of Fusarium displays extensive variability regarding pathogenicity and at a sub-specific level isolates have been classified into formae speciales and races according to host and cultivar range respectively (Garibaldi, 1977;Armstrong and Armstrong, 1981). These sub-specific taxa are morphologically indistinguishable (Jacobson and Gordon, 1991;Puhalla, 1981) and their validity as taxonomic units is unclear (Armstrong and Armstrong, 1975;Windels, 1991). Eight physiologic races of F. oxysporum f. sp.…”

Characterisation ofFusarium oxysporum isolated from carnation in Australia based on pathogenicity, vegetative compatibility and random amplified polymorphic DNA (RAPD) assay

Isolates of F. oxysporum collected from symptomless carnation cuttings from Australian carnation growers properties, together with isolates from national collections, were screened for pathogenicity and grouped according to vegetative compatibility and random amplified polymorphic DNA (RAPD) patterns. The collection of 82 Australian isolates sorted into 23 different vegetative compatibility groups (VCGs). Of 69 isolates tested for pathogenicity, 24 were pathogenic to carnations, while the remaining 45 were non-pathogenic. All pathogenic isolates were within two VCGs, one of which was also compatible with an isolate obtained from an international culture collection, and which is known to represent VCG 0021 and race 2. Race status of the two pathogenic VCGs remains unknown. The RAPD assay revealed distinct DNA banding patterns which could distinguish pathogenic from non-pathogenic isolates as well as differentiate between isolates from the two pathogenic VCGs. Fusarium oxysporumSchlecht. causes vascular wilt in a broad range of host plants including carnations (Dianthus caryophyllus L.). This species of Fusarium
