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.

[Antoine Guiguet @AntoineGuiguet]

The galls are so nutritious that psyllids that transitioned to galling have lost their nutritional symbionts ! 🤯https://t.co/7QPuPxPcVi

Immune activation by a phloem-colonizing plant pathogen drives citrus Huanglongbing disease development: Cell Host & Microbe https://t.co/l12R63h3Gi 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.

@SEBLASD Thank you SAR! What brave efforts to save others.

[Hansen Lab @HansenLab1]

@NWangUF @UF_IFASResearch Wow congratulations 🎊

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🦠

Vince and I are currently recruiting grad students for a variety of projects. Please pass on this flier to anyone you think would be interested!

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

[Jerry Maeda @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!

[Nicole Gerardo @NicoleGerardo]

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

Congrats to @kwak_younghwan our labs newly minted PhD. She will start a postdoc with Gordon Bennett soon continuing on the evolution of insect symbiosis. Good luck!!

[Nicole Gerardo @NicoleGerardo]

Excellent opportunity to do cool research.

[Lee Henry @HenryLabSymbio]

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.

Exciting news! Our undergrad Jacob and former grad Dohyup published a paper on comparative transcriptomics of obligate insect-microbe mutualisms. Discover the findings on key aphid homologs crucial for nutritional mutualism and lineage-specific genes at https://t.co/GDsNSqONeG.
