“…Depending on the stress type (wounding, herbivory, pathogen attack, dehydration, (UV) light, heat, etc. ), the composition and amounts of released VOCs can vary (Ferry et al 2004;Filella et al 2009;Jansen et al 2011;Kuhn et al 2004).…”

Characterization of Volatile Organic Compounds Emitted by Barley (Hordeum vulgare L.) Roots and Their Attractiveness to Wireworms

Root volatile organic compounds (VOCs), their chemistry and ecological functions have garnered less attention than aboveground emitted plant VOCs. We report here on the identification of VOCs emitted by barley roots (Hordeum vulgare L.). Twenty nine VOCs were identified from isolated 21-d-old roots. The detection was dependent on the medium used for root cultivation. We identified 24 VOCs from 7-d-old roots when plants were cultivated on sterile Hoagland gelified medium, 33 when grown on sterile vermiculite, and 34 on non-sterile vermiculite. The major VOCs were fatty acid derived compounds, including hexanal, methyl hexanoate, (E)-non-2-en-1-ol, nona-3,6-dien-1-ol, and nona-2,6-dien-1-ol. In an olfactometer assay, wireworms (larvae of Agriotes sordidus Illiger, Coleoptera: Elateridae) were attracted to cues emanating from barley seedlings. We discuss the role of individual root volatiles or a blend of the root volatiles detected here and their interaction with CO 2 for wireworm attraction.

“…Most insectresistant GM crops have been modified to express a variety of Bacillus thuringiensis (Bt) delta-endotoxins, but more recently plants expressing other insect-resistance proteins have been developed, including protease inhibitors (PIs), lectins and biotin-binding proteins (Ferry et al, 2004). Protease inhibitors bind to the active site of proteolytic enzymes, suppressing their catalytic activity (Laskowski and Kato, 1980).…”

Effects of tobacco genetically modified to express the protease inhibitor bovine spleen trypsin inhibitor (BSTI) were examined in laboratory assays against three earthworm and one collembolan species. BSTI is a serine protease inhibitor that can bind to the digestive trypsins of insects feeding on modified plants, resulting in reduced growth and survival. Protease inhibitors are active against a broad range of insects, so may have a large impact on non-target organisms. Survival and fecundity of the collembolan Folsomia candida were unaffected by consumption of artificial diet containing BSTI-expressing tobacco leaf or powdered freeze-dried BSTI-expressing tobacco leaf that was added to soil. Similarly, mortality and growth of earthworms Aporrectodea caliginosa and Lumbricus rubellus did not differ significantly between soil augmented with BSTI-expressing tobacco leaves or unmodified control leaves. The redworm Eisenia fetida gained less weight when provided with BSTI-expressing leaves in one assay, but when the experiment was repeated, there was no significant difference between treatments. BSTI-expressing tobacco and unmodified control leaves decomposed at the same rate, indicating that the inhibitor had no effect on the overall function of the decomposer community of micro-flora and fauna in soil.

“…Plant-insect interactions have been widely studied (Ferry et al 2004;Gatehouse 2002;Kessler and Baldwin 2002;Van Poecke 2007;Wu and Baldwin 2009). The resistances to herbivores in plants could be divided into two types, direct and indirect (Kessler and Baldwin 2002).…”

and four genes were significantly up-regulated in response to H. armigera in ED059 while down-regulated or not changed in cv. Tianlong 2. GO analyses showed the specifically expressed genes in ED059 were mainly enriched in metabolism-related pathways. The function of one potential resistant gene involved in the phenylpropanoid pathway was confirmed by use of transgenic Arabidopsis. Our study provided useful resources for the soybean improvement, which could contribute to the elucidation of defense mechanisms against chewing insects in plants.Keywords Soybean · Cotton bollworm · Transcriptome · Proteome · Defence Abstract Soybean is an important oil and protein crop in the world. Cotton bollworm (Helicoverpa armigera) is one of primary defoliating insects which seriously damage the soybean production. The wild soybean, ED059, was reported to be highly resistant to H. armigera. However, the molecular mechanism of resistance to H. armigera remains unknown. In this study, we conducted the transcript and protein profilings for ED059 and a susceptible soybean cultivar (cv.) Tianlong 2. In summary, 2213 genes and 116 proteins were specifically expressed in response to H. armigera in ED059, while 2179 genes and 9 proteins were specifically expressed in cv. Tianlong 2.
