Project description:• Herbivore-induced plant volatiles (HIPVs), in addition to attracting natural enemies of herbivores, can serve a signaling function within plants by acting as wound signals that induce or prime defenses. However, particularly in woody plants, which compounds within HIPV blends are capable of acting as signaling molecules are largely unknown. • Leaves of hybrid poplar (Populus deltoides x nigra) saplings were exposed in vivo to naturally wound-emitted concentrations of the green leaf volatile (GLV) cis-3-hexenyl acetate (z3HAC) and then subsequently fed upon by gypsy moth larvae (Lymantria dispar L.). Volatiles were collected throughout the experiments, and leaf tissue was collected to measure phytohormone levels and expression of defense-related genes. • Relative to controls, z3HAC-exposed leaves had higher levels of jasmonic acid and linolenic acid following gypsy moth feeding. Further, z3HAC primed transcripts of phytohormone signaling (lipoxygenase 1) and direct defense (a Kunitz proteinase inhibitor) genes. These qRT-PCR results were supported by microarray analysis using the AspenDB 7K EST microarray containing ~5400 unique gene models. Moreover, z3HAC also primed the release of herbivore-induced terpene volatiles. • The widespread priming response suggests an adaptive benefit to detecting z3HAC as a wound signal. Thus, woody plants can detect and use z3HAC as a signaling cue to prime defenses before actually experiencing damage. GLVs may therefore have important ecological functions in arboreal ecosystems.

Project description:Polyethylene pollutions are considered inert in nature and adversely affect the entire ecosystem. Larvae of greater wax moths (Galleria mellonella) have the ability to masticate and potentially biodegrade polyethylene films at elevated rates. The wax moth has been thought to metabolize PE independently of gut flora, however, the role of the microbiome is poorly understood and degradation by the wax moth might be involved. To determine whether the salivary glands of the wax moth were potentially involved in the PE degradation, it was investigated how surface changes of polyethylene were affected by mastication and consumption. Formation of pitting and degradation intermediates, including carbonyl groups, indicated that salivary glands could assist in polyethylene metabolism. We investigated the biochemical effect of exposure to PE on the composition of the salivary gland proteome. The expression of salivary proteins was found to be affected by PE exposure. The proteins that were significantly affected by the exposure to PE revealed that the wax moth is undergoing general changes in energy levels, and that enzymatic pathways associated with fatty acid beta oxidation were induced during PE consumption.

Project description:Plastics are highly stable materials with widespread applications, but their resistance to degradation poses a significant environmental challenge, often resulting in accumulation in landfills or pollution in the form of microplastics. Biodegradation using insect larvae has recently emerged as a promising strategy to address this issue, though the molecular basis of plastic degradation in these organisms remains poorly understood due to limited genomic resources. In this study, we present a complete genome of the lesser wax moth, Achroia grisella, and tissue-specific RNA-Seq data of both the lesser and the greater wax moth, Galleria mellonella, two species known to consume various plastics. Our analyses reveal several highly expressed secretory enzymes in gut and labial tissues. Orthologous comparisons of differentially expressed genes also identified five enzymes (three hexamerins and two monooxygenases) from the lesser wax moth that have been shown or are predicted to have plastic-degrading potential in the greater wax moth. We also identified enzymes that may potentially be involved in polyethylene and polystyrene degradation based on their identities with known bacterial enzymes that have been experimentally validated and are involved in plastic degradation pathways. Together, these genomic and transcriptomic resources provide a foundation for understanding plastic degradation in wax moths and highlight candidate genes for future functional validation.
