Defense enzymes induced in cucumber roots by treatment with plant growth-promoting rhizobacteria (PGPR) and Pythium aphanidermatum.
TLDR
The results suggest that the plant defense enzymes could be stimulated in cucumber roots which have been colonized by non-pathogenic rhizobacteria or in a compatible interaction between cucumber and P. aphanidermatum.

Defense responses induced by soluble silicon in cucumber roots infected by Pythium spp.
TLDR
The role of silicon (Si) in plant growth was investigated on the basis of induction of defense mechanisms in response to fungal attacks and glycosidically bound phenolics extracted from Si+ plants and subjected to acid or β-glucosidase hydrolysis displayed a strong fungistatic activity.

Effect of root and foliar applications of soluble silicon on powdery mildew control and growth of wheat plants
TLDR
The results lead to the conclusion that Si is primarily, if not exclusively, absorbed by the root system and that such absorption by the roots is necessary for an optimal prophylactic effect.

The protective role of silicon in the Arabidopsis–powdery mildew pathosystem
TLDR
It is demonstrated that Si treatment had no effect on the metabolism of unstressed plants, suggesting a nonessential role for the element but that it has beneficial properties attributable to modulation of a more efficient response to pathogen stress.

Silicon-mediated accumulation of flavonoid phytoalexins in cucumber.
TLDR
Conclusive evidence is presented that silicon is involved in the increased resistance of cucumber to powdery mildew by enhancing the antifungal activity of infected leaves by activating low-molecular-weight metabolites.
