Dear Colleagues, Friends, and Family 4/28/2026

It is with immense sadness and shock that I share the passing of Dr. Adriana Romero Olivares, a brand-new Assistant Professor in the Department of Evolution, Ecology and Organismal Biology at UC Riverside.

Variation in symbiont fitness during co-inoculations did not measurably affect plant performance, suggesting that predicted conflict over the joint phenotype of rhizobia fitness has negligible effect on the host.

Really Excited to get this great work out from Camille Wendlandt and others. #editorschoice

However, ineffective strains exhibited genotypic variation in their fitness in nodules within individual nodules co-infected with a beneficial strain, suggesting a role for symbiont competitiveness in shaping this joint phenotype.
