Last week I had the honor to lead an outreach workshop about Plant Galls at the award-winning #NorwichScienceFestival Participating nature detectives competed in teams to match galls to their insect inducers using custom-made flashcards with beautiful illustrations...

My Christmas plant disease illustration this year features Phytophthora ilicis, the oomycete responsible for holly leaf blight. 🎄🌿 hgpenningtonart.com/...
Illustration of a holly twig with several spiny green leaves showing brown blotches and pale, faded areas caused by Phytophthora ilicis infection. The stem is yellow-green and the background is plain white.

Had a great time treasure-hunting for galls with the British Plant Gall Society this weekend! Also proud to introduce my son to the amazing world of cecidology. 😍

First 2 months as a postdoc in the Hogenhout lab = whirlwind! Big goal: characterize bacterial effectors that turn plants 🪴 into zombies 🧟‍♀️. Really cool system that I've admired for years; also my first time working with plants and doing molecular work, so I'm learning A LOT! Some highlights: Y2H...🧵

Why do insect galls have such varied shapes even among closely related species?? The Enemy Hypothesis, posits that pressure from parasitoids drives the dynamic evolution of external gall traits. We have a new paper in @rsocpublishing.bsky.social on this hypothesis see more in this 🧵! 🧪 #galls
Many examples of the diversity in morphology of insect induced galls from hairy to colorful to spiky.

We’re delighted to share our latest preprint from the Hogenhout lab (@saskiahogenhout.bsky.social) on the molecular mechanisms on plant-aphid interactions. Here we show how the aphid Mp10 effector protein acts as a local anaesthetic to suppress the plant perception of aphid attack
