The products of a single maize sesquiterpene synthase form a volatile defense signal that attracts natural enemies of maize herbivores
Christiane Schnee,Tobias G. Köllner,Matthias Held,Ted C. J. Turlings,Jonathan Gershenzon,Jörg Degenhardt +5 more
TL;DR: It is demonstrated that a single gene such as tps10 can be sufficient to mediate the indirect defense of maize against herbivore attack and that females of the parasitoid Cotesia marginiventris learn to exploit the TPS10 sesquiterpenes to locate their lepidopteran hosts after prior exposure to these volatiles in association with hosts.

Priming by airborne signals boosts direct and indirect resistance in maize
Jurriaan Ton,Marco D'Alessandro,Violaine Jourdie,Gábor Jakab,Danielle Karlen,Matthias Held,Brigitte Mauch-Mani,Ted C. J. Turlings +7 more
TL;DR: In this paper, a differential hybridization screen for inducible genes upon attack by Spodoptera littoralis caterpillars identified 10 defence-related genes that are responsive to wounding, jasmonic acid (JA), or caterpillar regurgitant.
A Maize (E)-β-Caryophyllene Synthase Implicated in Indirect Defense Responses against Herbivores Is Not Expressed in Most American Maize Varieties
Tobias G. Köllner,Matthias Held,Claudia Lenk,Ivan Hiltpold,Ted C. J. Turlings,Jonathan Gershenzon,Jörg Degenhardt +6 more
TL;DR: It is argued that the (E)-β-caryophyllene defense signal was lost during breeding of the North American lines and that its restoration might help to increase the resistance of these lines against agronomically important pests.
Nitrogen supply affects arbuscular mycorrhizal colonization of Artemisia vulgaris in a phosphate-polluted field site
Verena Blanke,Verena Blanke,Carsten Renker,Markus Wagner,Kerstin Füllner,Matthias Held,Matthias Held,Arnd J. Kuhn,François Buscot +8 more
TL;DR: It is suggested that N deficiency stimulates root colonization by AMF in this extraordinarily P-rich field site.

The role of indole and other shikimic acid derived maize volatiles in the attraction of two parasitic wasps.
TL;DR: It is hypothesized that for naïve wasps the attractiveness of an herbivore-induced odor blend is reduced due to masking by nonattractive compounds, and that during oviposition experiences in the presence of complex odor blends, parasitoids strongly associate some compounds, whereas others are largely ignored.
