Sustained defense response via volatile signaling and its epigenetic transcriptional regulation.

Plants perceive volatiles emitted from herbivore-damaged neighboring plants to urgently adapt or prime their defense responses to prepare for forthcoming herbivores. Mechanistically, these volatiles can induce epigenetic regulation based on histone modifications that alter the transcriptional status of defense genes, but little is known about the underlying mechanisms. To understand the roles of such epigenetic regulation of plant volatile signaling, we explored the response of Arabidopsis (Arabidopsis thaliana) plants to the volatile β-ocimene.

Pest management using mint volatiles to elicit resistance in soy: mechanism and application potential.

Plants can eavesdrop on volatile cues emitted from neighboring plants to boost their defense responses. When 10 categories of mints were tested for their effects on Glycine max (soybean) plants cultivated nearby, candy mint (Mentha × piperita cv. Candy) and peppermint (Mentha × piperita L.
