More on silicon-induced resistance

摘要

Twelve genes, involved in defense, signal transduction, response to stresses, transcription, ubiquitinylation and metabolism, were up-regulated. A JAZ1-similar gene showed the highest level of up-regulation indicating prior induction and fine tuning of jasmonic acid signaling. Thus, we conclude that silicon primed plants, thereby alleviating biotic stress imposed by the pathogen. The primed state could be mediated via ethylene, jasmonic acid and/or reactive oxygen species signaling pathways. We also suggest that the protective role of silicon can not only be explained with its mechanical properties
