Control of Western flower thrips through jasmonate-triggered plant immunity

Chen, G. (2019)

Doctoral Thesis

We showed that constitutive and inducible chemical and morphological defenses against Western flower thrips differ between tomato and chrysanthemum plants. Furthermore, we demonstrated that both plant species respond differently to bacteria-derived defense elicitors, such as the phytotoxin coronatine. This highlights the plant species-specificity of these interactions and the possible limitation for the use of pathogen-associated molecular patterns to enhance the plant immune system. This study thus provides knowledge and novel strategies for Western flower thrips control. Yet, further comprehensive work is needed to evaluate the influence of these induction strategies on plant fitness.
