The role of indole in maize-herbivore interactions

Veyrat, Nathalie ; Turlings, Ted (Dir.)

Thèse de doctorat : Université de Neuchâtel, 2014.

In order to counter herbivore attacks, plants have developed a multitude of defence strategies, including the release herbivore-induced plant volatiles (HIPVs). HIPVs can be used as foraging cues by natural enemies of the herbivores, including predators and parasitoids. In addition, they can also be exploited by herbivores themselves to localize their host plants. Some HIPVs even prime...

Direct and indirect effect of the rhizobacteria 'Pseudomonas putida' KT2440 on maize plants

Planchamp, Chantal ; Mauch-Mani, Brigitte (Dir.)

Thèse de doctorat : Université de Neuchâtel, 2013.

To protect themselves against biotic and abiotic stresses, plants have developed a broad range of defense mechanisms that are constitutively present or that can be induced in response to a stress. Such induced defense can be the result of a resistance elicitation by non-pathogenic organisms that are present in soil and is then called induced systemic resistance (ISR). ISR confers plant resistance...

Parasotoid communities and genetic structure : host plant does not matter

Jourdie, Violaine ; Turlings, Ted (Dir.)

Thèse de doctorat : Université de Neuchâtel, 2008 ; Th. 2050.

Plant-insect interactions have long been studied and reveal intricate mechanisms. Plants are capable of defending themselves both directly by poisoning insect herbivores and indirectly by emitting volatile compounds that are used by the natural enemies to localize their host. In response, insects have evolved strategies to defeat plant defense mechanisms. Because insect pests are affected by...

Belowground tritrophic interactions

Rasmann, Sergio ; Turlings, T. (Dir.)

Thèse de doctorat : Université de Neuchâtel, 2006 ; 1849.

In response to phytophagous insects attack, plants produce volatile compounds that can serve as cues for natural enemies of the herbivore to locate their host or prey. Very substantial progress has been made in understanding such tritrophic interactions aboveground. Recently, however, it is more and more recognized that aboveground communities are influenced through physiological and biochemical...
