Plant defense negates pathogen manipulation of vector behavior

Baiming Liu, Evan L. Preisser, Xiaobin Shi, Huaitong Wu, Chuanyou Li, Wen Xie, Shaoli Wang, Qingjun Wu, Youjun Zhang Many important and economically-damaging plant pathogens are transmitted by insect vectors, and pathogens have been shown to alter vector behavior in ways that promote both their uptake and transmission.

“Cagey” trees have safer lives

Tristan Charles-Dominique, Jean-Francois Barczi, Elizabeth Le Roux and Simon Chamaillé-Jammes Where large browsers such as impalas or kudus are abundant, trees survive only if they have chemical or structural defences. Structural defences include the arrangement of dense and intricate architecture, termed ‘cage’ architecture. Previous studies showed that trees developing in herbivore-rich environments tend to have…
