Abstract:
... A glycopeptide elicitor prepared from germ tubes of the rust fungus Puccinia graminis Pers. f. sp. tritici Erikss. & Henn (Pgt),as well as chitin oligosaccharides, chitosan, and methyl jasmonate (MJ) stimulated lipoxygenase (LOX) activity (E.C. 1.13.11.12) in wheat (Triticum aestivum) leaves. Immunoblot analysis using anti-LOX antibodies revealed the induction of 92- and 103-kD LOX species after P ...

Abstract:
... Fusarium culmorum can cause Fusarium head blight (FHB) disease of cereals, resulting in yield loss and contamination of grain with the trichothecene mycotoxin, deoxynivalenol (DON). In this study, we compared the efficacy of a biological control agent (Pseudomonas fluorescens strain MKB 158) with the biochemical chitosan (the deacetylated derivative of chitin) in controlling FHB disease of wheat a ...

Abstract:
... The multilayered plant immune system relies on rapid recognition of pathogen‐associated molecular patterns followed by activation of defense‐related genes, resulting in the reinforcement of plant cell walls and the production of antimicrobial compounds. To suppress plant defense, fungi secrete effectors, including a recently discovered Zn‐metalloproteinase from Fusarium verticillioides, named fung ...

Abstract:
... Heterodera avenae is a devastating plant pathogen that causes significant yield losses in many crops, but there is a lack of scientific information whether this pathogen can be controlled effectively using biocontrol agents. Here we determined the parasitic and lethal effects of Trichoderma longibrachiatum against H. avenae and the possible mechanism involved in this action. Both in vitro and gree ...

Abstract:
... SnTox1 induces programmed cell death and the up‐regulation of pathogenesis‐related genes including chitinases. Additionally, SnTox1 has structural homology to several plant chitin‐binding proteins. Therefore, we evaluated SnTox1 for chitin binding and localization. We transformed an avirulent strain of Parastagonospora nodorum as well as three nonpathogens of wheat (Triticum aestivum), including a ...

Abstract:
... The ability of soils to detain the onset of a disease in a susceptible host is called soil suppressiveness. Soil suppressiveness can often be attributed to the activity of soil microorganisms. Considering that soil management can drastically affect microbial soil communities, the objective of this work was to evaluate the impact of different crop systems and tillage practices on the suppression of ...

Abstract:
... Plant subtilases (SBTs) or subtilisin-like proteases comprise a very diverse family of serine peptidases that participates in a broad spectrum of biological functions. Despite increasing evidence for roles of SBTs in plant immunity in recent years, little is known about wheat (Triticum aestivum) SBTs (TaSBTs). Here, we identified 255 TaSBT genes from bread wheat using the latest version 2.0 of the ...
