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🦠

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

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

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

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!!

Excellent opportunity to do cool research.
A postdoc position is open in my lab! We are using ecological principles to investigate coexistence in aquatic microbial communities. See the posting for more information and to apply: jobs.boisestate.edu/en-us/jo…. Please share!

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 nature.com/articles/s41598-0….
