Development of Heterodera glycines as Affected by Fusarium solani, the Causal Agent of Sudden Death Syndrome of Soybean.
Journal of Nematology, 1995Co-Authors: Kathy S. Mclean, Gary W. LawrenceAbstract:The effects of the blue form of Fusarium solani, the causal agent of sudden death syndrome (SDS), on Heterodera glycines were examined in the greenhouse. Roots of soybean cv. Coker 156 were inoculated with either H. glycines alone or F. solani + H. glycines in combination. Population levels of H. glycines were reduced 47% in the presence of F. solani. Life-stage development of H. glycines increased 3% in 30 days in the presence of F. solani. Fusarium solani colonized epidermal and cortical cells adjacent to developing juveniles of H. glycines and the nematode-induced syncytia within the soybean root tissue. At 40 days after inoculation, F. solani was isolated from 37% of the cysts in soil recovered from the F. solani + H. glycines combination treatment. Fusarium solani significantly affected H. glycines population density, life-stage development, and succeeding populations. Key words: Fusarium solani, Heterodera glycines, histology, interaction, nematode, soybean, soybean cyst nematode, sudden death syndrome.

Interrelationship of Heterodera glycines and Fusarium solani in Sudden Death Syndrome of Soybean
Journal of Nematology, 1993Co-Authors: Kathy S. Mclean, Gary W. LawrenceAbstract:Experiments were established in field microplots to examine the association between Heterodera glycines and the blue form of Fusarium solani in sudden death syndrome of soybean (SDS). Foliar disease symptoms occurred on more plants per plot, appeared 3 to 7 days earlier, and were more severe on plants grown in plots infested with F. solani + H. glycines than on those inoculated with F. solani only. Yields were suppressed only in treatments that included the nematode. Numbers of H. glycines cysts and second-stage juveniles were significantly lower in plots infested with F. solani + H. glycines than with the nematode alone. Fusarium solani was able to infect cysts and eggs.

rhizobium japonicum as a biocontrol agent of soybean root rot disease caused by Fusarium solani and macrophomina phaseolina
Plant protection science, 2018Co-Authors: Rakib A Alani, Mustafa A Adhab, M H Mahdi, H M AboodAbstract:Al-Ani R.A., Adhab M.A., Mahdi M.H., Abood H.M. (2012): Rhizobium japonicum as a biocontrol agent of soybean root rot disease caused by Fusarium solani and Macrophomina phaseolina. Plant Protect. Sci., 48: 149–155. The activity of Rhizobium japonicum against the soil-borne pathogens Fusarium solani and Macrophomina phaseolina as causative agents of soybean root rot disease in both culture medium and soil was evaluated. Rhizobial culture filtrate caused an inhibition of the fungal radial growth of Fusarium solani and Macrophomina phaseolina on potato dextrose agar medium amended with the filtrate compared with control. The addition of rhizobial culture suspension to the soil contaminated by the two pathogens, Fusarium solani and Macrophomina phaseolina and their interaction, in pots, improved seed germination percentages and reduced the root rot disease index significantly. The sowing of rhizobial coated seeds in soil contaminated by Fusarium solani and Macrophomina phaseolina separately and in combination, in the field, increased seed germination significantly and induced a high reduction in disease severity for the same previous combination under field conditions. These results indicate that rhizobia could be an important element in root rot disease management.

universal in vitro antifungal resistance of genetic clades of the Fusarium solani species complex
Antimicrobial Agents and Chemotherapy, 2007Co-Authors: Monica Azor, Josepa Gene, Josep Cano, Josep GuarroAbstract:Eleven antifungal drugs were tested against representative isolates of the four phylogenetic clades of the Fusarium solani species complex obtained in a multilocus sequence analysis. They all showed very poor activity, with no differences among the clades. Amphotericin B was the most active drug.

Trichothecene inhibitors of Striga hermonthica germination produced by Fusarium solani
Weed Science, 2002Co-Authors: Yukihiro Sugimoto, Nafisa E. Ahmed, Norifumi Yasuda, Shinobu InanagaAbstract:Abstract Metabolites of the fungus Fusarium solani (Sud 96) inhibited Striga hermonthica germination induced by the germination stimulant GR24. The active principles were identified as trichothecenes acuminatin, neosolaniol, 8-acetylneosolaniol, and tetraacetoxy T-2 tetraol (neosolaniol diacetate) on the basis of their chromatographic behavior and nuclear magnetic resonance and mass spectra. Inhibitory activity of the four trichothecenes against Striga germination increased with acetylation of the hydroxyl moieties. The most abundant inhibitor produced by the fungus, 8-acetylneosolaniol, completely inhibited Striga germination at 24 μM. The fungal toxin did not affect the germination of sorghum, a host crop, but retarded root and shoot elongation of the seedlings by 60 and 30%, respectively, at the same concentration. Nomenclature: Fusarium solani (Mart.) Sacc.; sorghum, Sorghum bicolor (L.) Moench; Striga hermonthica (Del.) Benth.

Effects of Fusarium solani isolates and metabolites on Striga germination
Weed Science, 2001Co-Authors: Nafisa E. Ahmed, Yukihiro Sugimoto, Shinobu Inanaga, A. G. T. Babiker, Omayma E. Mohamed, Yongqing Ma, Hiromitsu NakajimaAbstract:Abstract An isolate of Fusarium solani (Sud 96) obtained from infected Striga plants in Sudan and six other isolates from Japan were evaluated for their effects on Striga germination. Among all the isolates, only the one from Sudan demonstrated high inhibitory activity. Aqueous and organic solvent culture extracts, as well as fungus suspension, when mixed with GR24, a synthetic analog of the natural germination stimulant strigol, inhibited germination of conditioned Striga seeds. Fusarium solani (Sud 96) filtrates, from cultures grown on autoclaved rice, sorghum grains, and potato dextrose agar (PDA), were more effective in reducing Striga germination than those from cultures grown on wheat straw. A significant difference between rice compared to sorghum and PDA cultures only occurred at high dilutions (40-fold). Complete inhibition of germination occurred when F. solani (Sud 96) culture filtrates and GR24 were applied simultaneously. Filtrate treatments made 2, 4 and 6 h subsequent to treatment with GR24...
