Soybean Sudden Death Syndrome Caused by Fusarium virguliforme is Impaired by Prolonged Flooding and Anaerobic Conditions

Abstract: High soil moisture usually favors soybean sudden death syndrome (SDS), caused by Fusarium virguliforme (Fv), but the effects of the duration of the flooding period and accompanying anaerobic conditions on the soybean-Fv interaction are not clear. Greenhouse studies were conducted using susceptible and resistant cultivars exposed to the following treatments: 3, 5, or 7 days of continuous flooding, repeated short-term flooding of 8 h/week for 3 weeks, and a no-flood check treatment. At 7, 14, and 21 days after f… Show more

“…Nevertheless, a reduction of foliar and root rot severity caused by F. virguliforme was observed after continuous flooding of a greenhouse for 5 or 7 days (Abdelsamad et al, 2017). As flooding causes lack of oxygen in the soil, Abdelsamad et al (2017) also evaluated the effect of anaerobic conditions on the soybean-F. virguliforme interaction.…”

As flooding causes lack of oxygen in the soil, Abdelsamad et al (2017) also evaluated the effect of anaerobic conditions on the soybean-F. virguliforme interaction. After an exposure to anaerobic conditions for 6 hr, soybean genes related to defence responses and F. virguliforme candidate virulence genes were down-regulated (Abdelsamad et al, 2017).…”

“…Soil temperature and moisture influence early season Fv infection, and canopy symptoms that are most common during the reproductive (late) growth stages [23,28]. The balance between environmental conditions influence on the pathogen and the host plays a role in the severity of the canopy symptoms [29] that can fluctuate from very light chlorosis to necrosis and complete premature defoliation in a matter of days. In cases of no apparent canopy symptoms, the pathogen can remain unnoticed in the soil, infected roots or plant residue as a potential risk for subsequent growing seasons.…”
