“…(2006) reported that exposure of lima bean plants to HIPVs from conspecific plants infested with Tetranychus urticae increased fructose and glucose in their extrafloral nectary. The biosynthesis of secondary compounds in a plant is affected by the exposure of volatiles in plant-plant communication ( Ozawa et al., 2013 ; Shiojiri et al., 2017 ; Shiojiri et al., 2020b ; Brosset and Blande, 2022 ). For example, exposure of black and yellow soybean plants to goldenrod volatiles resulted in an increase in seed isoflavones and saponins ( Shiojiri et al., 2017 ; Shiojiri et al., 2020b ).…”

Plants exposed to volatiles emitted from artificially damaged conspecific or heterospecific plants exhibit increased resistance to herbivorous insects. Here, we examined whether volatiles from artificially damaged weeds affect maize growth and reproduction. Seven days after germination, maize seedlings were exposed to volatiles emitted by artificially damaged mugwort (Artemisia indica var. maximowiczii) or tall goldenrod (Solidago altissima) plants either separately, or as a mixture of the two, for seven days. Unexposed seedlings were used as controls. Treated and control seedlings were cultivated in an experimental field without any insecticides applied. Plants exposed to either of the three volatile treatments sustained significantly less damage than controls. Additionally, seedlings exposed to either goldenrod or mixed volatiles produced more leaves and tillers than control plants. Furthermore, a significant increase in the number of ears was observed in plants exposed to the volatile mixture. In all treated plants, ear sugar content was significantly higher than that in the controls. Further, we cultivated seedlings that were either exposed to the volatile mixture or unexposed, under the conventional farming method using pesticides. Similar significant differences were observed for sugar content, number of tillers, leaves, damaged leaves, and ears. Laboratory experiments were conducted to further evaluate the mechanisms involved in the improved performance of volatile-treated plants. A significant reduction in the growth of common armyworm (Mythimna separata) larvae was observed when maize plants were exposed to the volatile mixture. This treatment did not affect the amount of jasmonic acid in the seedlings, whereas salicylic acid content increased upon exposure. The characteristic differences in chemical composition of mugwort and goldenrod volatiles were confirmed and, in turn, the volatile mixture differed significantly from the volatiles of either species.

“…The number of localized responses that would be aided by the increased specificity afforded by obtaining quality RNA from tissue sections is vast (Santos et al 2012;Ghodke et al 2013;Gupta et al 2013;Ozawa et al 2013). For example, plant parasitic nematodes cause as much as 100-150 billion dollars in damage annually, worldwide (Sasser & Freckman 1987;Chitwood 2003).…”

“…This problem would represent a major challenge for genomics studies involving plant-organism interactions because of the varied position of the pathogen, the limited amount of sample, and technical problems involved in isolating individual cells. However, the number of localized responses that would be aided by the increased specificity afforded by obtaining quality RNA from semi-thin sections is extensive (Santos et al 2012;Ghodke et al 2013;Gupta et al 2013;Ozawa et al 2013).…”

Salicylhydroxamic acid (SHAM) negatively mediates tea herbivore-induced direct and indirect defense against the tea geometrid Ectropis obliqua

et al. 2014

We investigated the effect of the SHAM treatment of tea plants on their induced defense on a tea geometrid (TG), Ectropis obliqua Prout. Treatment of tea leaves with SHAM reduced the performance of TG and TG-elicited level of the lipoxygenase gene CsiLOX1 and the putative allene oxide synthase gene CsiAOS1. The release of wound-induced green leaf volatiles (GLVs) and the expression of the hydroperoxide lyase (HPL) gene CsiHPL1 were also reduced by SHAM treatment. The negative effect of SHAM dramatically reduced the total hebivore-induced plant volatiles (HIPVs) and the attractiveness to the parasitoid wasp Apanteles sp. These results indicated that SHAM may negatively mediate tea defense response against TG by modulating the wound-induced emission of GLVs, the expression of genes involved in oxylipin pathway, and the emission of other HIPV compounds that mediate direct and indirect defenses.
