TL;DR: It is demonstrated that cabbage loopers (Trichoplusia ni) display rhythmic feeding behavior that is sustained under constant conditions, and plants entrained in light/dark cycles coincident with the entrainment of the T. ni suffer only moderate tissue loss due to herbivory, and salicylate, a hormone involved in biotrophic defense that often acts antagonistically to jasmonates, accumulates in opposite phase to jAsmonates.

TL;DR: The employment of various genetic, biochemical, and molecular tools may enable elucidation of the mechanisms through which plants perceive mechano-stimuli and transduce the signals intracellularly to induce appropriate responses.

TL;DR: The role of AA, an ancient metazoan signaling molecule, in eliciting plant stress and defense signaling networks is supported, and its effect on biotic stress resistance is examined by challenging EP plants with fungal, oomycete, and bacterial pathogens and an insect pest.

TL;DR: It is shown that jasmonate (JA) phytohormone both is required for and promotes the salient characteristics of thigmomorphogenesis in Arabidopsis, including a touch-induced delay in flowering and rosette diameter reduction, and that repetitive mechanostimulation enhancesArabidopsis pest resistance in a JA-dependent manner.

TL;DR: It is found that the Arabidopsis SWI/SNF class chromatin remodeling ATPase SPLAYED (SYD) is required for the expression of selected genes downstream of the jasmonate (JA) and ethylene (ET) signaling pathways, and it is shown that SYD is necessary for resistance against the necrotrophic pathogen Botrytis cinerea but not the biotrophic Pathogen Pseudomonas syringae.
