Fun collaboration with Diana Percy and Patrick Degnan showing rapid loss (<1M) of nutritional symbionts in Hawaiian psyllids is associated with galling behavior. All psyllids (free-living, open gall, closed gall) radiated on the same host plant species over ~5MY.

The galls are so nutritious that psyllids that transitioned to galling have lost their nutritional symbionts ! 🤯academic.oup.com/mbe/article…

Immune activation by a phloem-colonizing plant pathogen drives citrus Huanglongbing disease development: Cell Host & Microbe cell.com/cell-host-microbe/f… Glad to share our recent progress on citrus HLB. Kudos to the co-first authors Xianen, Wenxiu, Wenting, and Yu and other colleagues in my lab. It is truly a team work by collaboration with Allison K. Hanse at UCR, Ning Zhang at JMU, and Madhurababu Kunta at TAMUK.

NEW PAPER! What explains associations with defensive symbionts? In @Ecology_Letters we show symbiont occurrences align with sharing the same parasitoids, but not plants, highlighting enemies as key selective agents shaping symbioses in nature🦠

Cool paper on convergent losses of a symbiont in gall forming insects! Nice work by @HansenLab1 Patrick Degnan et al. 🦠🌺

Excited to learn our non-transgenic canker-resistant citrus generated by crispr genome editing exempted by EPA, by APHIS, for use by growers! They are the 1st to receive EPA exemption for gene-edited plants! ThanksNIFA funding!Thanks@usda_nifa @EPA@USDA_APHIS

Super cool study culturing an important secondary symbiont of aphids by @gpmaeda

My first dissertation chapter is out in mBio! We cultured a vertically transmitted endosymbiont, sequenced its genome, and showed that it is stably inherited across generation when injected into new hosts!

Beautiful (both visually and scientifically) research by @thyreodon testing the role of chance in shaping animal-microbe symbioses.

Study of #SquashBug colonization by #bacterial #symbionts shows that heterogeneity & strain diversity in symbiotic microbial communities, within- & between-host, can be explained by stochastic colonization @thyreodon @NicoleGerardo @nicvega1 #PLOSBiology plos.io/4dceo21

New paper alert! Symbionts have allowed insects to colonise novel feeding niches, but how has this influenced diversification? In @NatureEcoEvo we show that symbionts are associated with extreme highs and lows of insect diversification.
