Microbial determinants of behaviour in herbivorous beetles (SALEM_J26DTP) | Doctoral Training Partnership Many animals rely on beneficial microbes for nutrition, defence, or reproduction. In this project, the student will explore an exciting new dimension of these relationships:

There’ll be several opportunities to join the group, starting w/ a PhD studentship via the BBSRC-NRP Doctoral Training Partnership.

Team up w/ us, @saskiahogenhout.bsky.social & @berasymbionts.bsky.social to answer how microbes shape insect behavior:

Ecological stoichiometry of mountain pine beetle, its mutualist fungi, and the disease white pine blister rust in whitebark pine - Oecologia Ecological stoichiometry can help clarify how symbionts and other co-occurring organisms mediate nutrient deficiencies for hosts. We used ecological stoichiometry (comparisons of elemental composition...

We have a new one out!

I know this is a weird time to ask, but are there post doc positions in symbiosis available in the next year? I know a talented microscopy/microbiology student who is going to be on the job market soon. Open to work outside the US, but is an American student if that makes a difference🧪🦠

A dual insect symbiont and plant pathogen improves insect host fitness under arginine limitation | mBio Unlike obligate symbionts that are permanently associated with their hosts, facultative symbionts rarely show direct nutritional contributions, especially under nutrient-limited conditions. This study...

New study from my lab and former grad Dr. Kwak shows Liberibacter psyllaurous, a dual insect symbiont and plant pathogen, boosts psyllid fitness by providing essential nutrients like arginine. A rare case of nutritional benefits from non-obligate symbionts #symbiosis journals.asm.org/doi/10.1128/...

Base-modified nucleotides mediate immune signaling in bacteria Signaling from pathogen sensing to effector activation is a fundamental principle of cellular immunity. While cyclic (oligo)nucleotides have emerged as key signaling molecules, the existence of other ...

Fun new paper led by @greghurst.bsky.social &co using genomics to show that facultative symbiont genomes get bigger as they adapt to life inside a host (through HGT & loss of CRISPR) before undergoing genome reduction as they become obligate #symbiosky #microsky
