Plants have evolved intriguing defences against insect herbivores. Compared to constitutive Plants have evolved intriguing defences against insect herbivores. Compared to constitutive defences that are always present, plants can respond with inducible defences when they are attacked. Insect herbivores can induce phenotypic changes in plants and con...
SummaryAquatic photosynthetic organisms unavoidably experience light fluctuations that vary in amplitude, duration and origin, compromising their photosynthetic efficiency. Weather conditions and underwater flow cause continuous changes in irradiance to which the organisms have to adapt. Many light-adaptation strategies of photosynthetic organisms,...
It is fascinating that our ecological systems are structured by both direct and indirect species interactions. In terrestrial ecosystems, plants interact with many species of insects that include both harmful herbivores and beneficial natural enemies of herbivores. During the last 30 years, substantial progress has been made in different plant-inse...
Summary Lipopeptides (LPs) are surface-active, antimicrobial compounds composed of a lipid moiety linked to a short linear or cyclic oligopeptide. In bacteria, LPs are synthesized by large nonribosomal peptide synthetases (NRPSs) via a thiotemplate process. Compared to the understanding of LP biosynthesis, little is known about the genetic regulati...
Tomato (Solanum lycopersicum) is affected by a wide range of biotic stresses, of which Bemisia tabaci is one of the most important.Bemisia tabaci affects tomato directly through phloem sap feeding, and indirectly through its ability to be the vector of a large number of viruses. Different methods are available for whitefly control, and although sev...

Botrytis leidt in snijbloemen nog steeds tot veel uitval. Resistente rassen zijn niet beschikbaar. Wel zijn er duidelijke verschillen in gevoeligheid tussen cultivars aanwezig. Eén van de manieren om planten zich beter te laten weren tegen Botrytis is om de aanmaak van natuurlijke afweerstoffen te activeren. Kennis over het primen van planten in si...
Fungi are notorious plant pathogens and continuously threat global food production. In the last decades we have obtained a better understanding of infection strategies of fungi and the plant immune system. This has facilitated more efficient introduction of disease resistance genes in crop plants by plant breeders. A brief overview of progress in r...
Met een goede klimaatbeheersing kan de teler Botrytis in de hand houden. Maar eigenlijk is de weerbaarheid van de plant bij deze schimmel veel belangrijker. Bij een hogere weerbaarheid hoef je veel minder scherp op het klimaat te letten en bespaar je op het middelengebruik. Diverse onderzoekinstellingen werken aan meer inzicht.
