Inactivation effects of plasma-activated water on Fusarium graminearum

The results showed that microbial activity of spores was significantly inhibited by Plasma-activated water treatment



Scholarcy highlights

  • Phytopathogens are the main causes of plant diseases, they significantly reduce the yield of agricultural crops
  • When the discharge area is below the water surface, there are more changes for the oxygen or reactive oxygen species in air plasma to oxidize the nitrite in Plasma-activated water
  • The results from SEM and transmission electron microscopy observations in this study showed that PAW could cause the surface sculpturing in the cell walls of spores, which may be attributed to the oxidative damage induced by reactive species in PAW
  • The results from our study confirmed that PAW treatment is a highly effective disinfection procedure against F. graminearum
  • The DESeq2 sequencing analysis enhanced the hypothesis by the fact that there were three putative genes involved in mitochondrial function in the 10 most upregulated genes and one gene involved in the cell membrane in the top 5 downregulated genes in response to PAW treatment
  • The information obtained from this work may verify the feasibility and validity of the application of this technique in plant disease control and provides important insights into the antifungal mechanism of PAW to fight against F. graminearum
