In this century the human being must face the challenges of producing enough to feed a growing population in a sustainable and environmentally friendly way. The yields are with increasing frequency affected by abiotic stresses such as salinity, drought, and high temperature or by new diseases and plagues. The Research Topic on Induced Resistance for Plant Defense focuses on the understanding the mechanisms underlying plant resistance or tolerance since these will help us to develop fruitful new agricultural strategies for a sustainable crop protection. This topic and its potential applications provide a new sustainable approach to crop protection. This technology currently can offer promising molecules capable to provide new long lasting treatments for crop protection against biotic or abiotic stresses. The aim of this Research Topic is to review and discuss current knowledge of the mechanisms regulating plant induced resistance and how from our better understanding of these mechanisms we can find molecules capable of inducing this defence response in the plant, thereby contributing to sustainable agriculture we need for the next challenges of the XXI century.

In search for alternatives to conventional pesticides, priming appeared to be an interesting finding as a prophylactic treatment of crops, at low fitness cost. In this respect, only few research has been conducted on the priming potential of essential oils, which are already known for their multiple properties and are raising interest in agriculture. The priming effect of seed coating with (the thujone- free) Artemisia absinthium L. var. candial® essential oil (AEO) on Solanum lycopersicum L. has been proven effective against Fusarium oxysporum. Therefore, in this study, its effect against the common pests Myzus persicae and Meloidogyne javanica, respectively on Capsicum annuum L. and S. lycopersicum, was investigated. In vitro assays confirmed that AEO was not nematicidal, had a low activity against aphids and that it was not phytotoxic to pepper. It was detrimental for tomato seeds’ germination from a concentration of 5 mg/mL but the in vivo experiments highlighted that the resulting plants were, visually, healthy. On one hand, the biological observations made during the in vivo assays showed no effect against M. javanica but an increase in reproduction of M. persicae on treated peppers and significant differences in weight of roots and aerials. On the other hand, GC- and HPLC- MS analyses of the secondary metabolites synthesized in the aerial parts of both peppers and tomatoes, revealed that the seed coating by AEO, did trigger a response. To allocate the differences observed between treated, non-treated, infected and non-infected plants, to priming of defenses, additional data need to be collected. The most promising route for further investigation would be to apply the AEO-priming-treatment at a later growth stage. Several suggestions are provided in the perspectives. Dans la recherche d’alternatives aux pesticides conventionnels, le «priming» représente une découverte intéressante en tant que traitement prophylactique, à moindre coût pour les plantes cultivées. Très peu de recherches ont été effectuées dans cette optique, sur les huiles essentielles, dont les multiples propriétés sont pourtant bien connues et rencontrent un succès grandissant dans le domaine de l’agriculture. L’effet de « priming » de l’huile essentielle d’Artemisia absinthium L. (HEA) (de la variété candial® qui ne possède pas de thujone), administrée par enrobage de la graine, a déjà été démontré sur Solanum lycopersicum L. contre Fusarium oxysporum. C’est pourquoi, dans le cadre de ce travail, son effet contre les ravageurs communs Myzus persicae et Meloidogyne javanica, sur respectivement, Capsicum annuum L. et S. lycopersicum a été investigué. Les essais in vitro ont confirmé que l’HEA n’était pas nématicide, possédait une faible activité contre les pucerons et n’était pas phytotoxique pour le poivron. Elle était néfaste pour la germination des graines de tomate à partir d’une concentration de 5 mg/mL mais les expériences in vivo ont mis en évidence que les plantes en résultant étaient, visuellement, saines. En ce qui concerne les essais in vivo, d’une part, les observations biologiques n’ont montré aucun effet contre M. javanica mais une augmentation de la reproduction de M. persicae sur les poivrons traités et des différences significatives entre les poids des racines et des parties aériennes des poivrons testés. D’autre part, les analyses GC- et HPLC-MS des métabolites secondaires synthétisés dans les parties aériennes des poivrons et des tomates, ont révélé que l’enrobage des graines avec l’HEA, a bel et bien stimulé une réponse chez les plantes. Pour pouvoir attribuer les différences observées, entre plantes traitées, non-traitées, infectées et non-infectées, au « priming », des données supplémentaires devraient être récoltées. La piste la plus prometteuse pour approfondir les recherches futures serait d’appliquer le traitement de l’HEA à un stade de développement de la plante, plus avancé. Plusieurs suggestions sont formulées dans les perspectives.

Doelstelling: Deze masterproef handelt over de onderlinge volgorde van bijwoordelijke bepalingen in Nederlandse vertalingen. Aan de hand van een corpusstudie zijn we nagegaan of die volgorde beïnvloed wordt door de positie van bijwoordelijke bepalingen in de Engelse bronteksten. Middelen of methode: Binnen de journalistieke en administratieve teksten van het parallelle corpus DPC (Dutch Parallel Corpus) zijn we op zoek gegaan naar vertaalparen die minstens twee bijwoordelijke bepalingen van tijd, plaats of wijze bevatten. Vervolgens werd de onderlinge volgorde van die bijw. bepalingen in de bron- en de doeltekst met elkaar vergeleken, om verschillen en gelijkenissen na te gaan. Deze analyse gebeurde per paar: plaats – tijd, tijd – wijze en wijze – plaats. Het doel was om te onderzoeken wanneer en waarom de vertaler de volgorde van de brontaal overnam of veranderde in zijn/haar vertaling, en of die keuze beïnvloed werd door interferentie van de brontaal. Resultaten: In geen enkele van de combinaties plaats/tijd, tijd/wijze of wijze/plaats konden we de verandering of het behoud van de volgorde in de brontekst eenduidig toeschrijven aan interferentie van de brontekst zelf. De keuze van de vertaler om de volgorde te behouden of te wijzigen waren veeleer het gevolg van de syntactische structuur van de doeltaal.
