چکیده

for determination the host range of fusarium stem and root rot of green-house cucumber (cucumis sativus) that caused by fusarium oxysporum f. sp. radicis-cucumerinum, after isolation, identification and study of pathogenisity, 16 species of several plant families were artificially inoculated with this pathogen by sand and corn meal contaminated with pathogen, two varieties of cucumis melo, of cucurbitaceous developed stem and root rot symptoms similar to those that were developed on cucumber. symptomology and host range studies indicate that this pathogen is f. oxysporum f. sp. radicis-cucumerinum. reactions of 20 cucumber cultivars were tested, ranged from susceptible to tolerant to this disease under glasshouse conditions showed that the tolerant cultivars were 120118, ayat, fd-c101, festival, jakie, khassib, psr36-45007, sr36-45664 and storm and the most susceptible cultivars were 32-pv, 8-ayat, cb61688222, janette, nasco, negeen, nicoo 100, psr36-47112, rubah-l, rubah-s and soltan.

Differential Responses of Vanilla Accessions to Root Rot and Colonization by Fusarium oxysporum f. sp. radicis-vanillae

Root and stem rot (RSR) disease caused by Fusarium oxysporum f. sp. radicis-vanillae (Forv) is the most damaging disease of vanilla (Vanilla planifolia and V. × tahitensis, Orchidaceae). Breeding programs aimed at developing resistant vanilla varieties are hampered by the scarcity of sources of resistance to RSR and insufficient knowledge about the histopathology of Forv. In this work we have (...

Water balance altered in cucumber plants infected with Fusarium oxysporum f. sp. cucumerinum

Fusarium wilt is caused by the infection and growth of the fungus Fusarium oxysporum in the xylem of host plants. The physiological responses of cucumbers that are infected with Fusarium oxysporum f. sp. cucumerinum (FOC) was studied in pot and hydroponic experiments in a greenhouse. The results showed that although water absorption and stem hydraulic conductance decreased markedly in infected ...

Velvet genes play critical roles in the regulation of diverse cellular processes. In current study, we identified the gene FocVel1, a homolog of Fusarium graminearum VelA, in the plant pathogenic fungus F. oxysporum f. sp. cucumerinum. This pathogen causes the destructive disease called cucumber Fusarium wilt (CFW), which severely affects the production and marketing of this vegetable worldwide...
