New paper by Meng Mao and Allen Yang titled "Evolution of host support for two ancient bacterial symbionts with differentially degraded genomes in a leafhopper host" was just published in PNAS!

This work shows that the aster leafhopper (Macrosteles quadrilineatus), which depends on two symbionts with tiny genomes (Sulcia and Nasuia), has differentially reprogramed gene-expression patterns in symbiont-associated cells. The aster leafhopper has also acquired novel genetic traits and likely recruited preexisting mitochondrial support mechanisms to meet the specific needs of each symbiont.

New paper by former lab technician and postdoc, Kylle Roy and Curtis Ewing titled "Presence and viability of Ceratocystis lukuohia in ambrosia beetle frass from Rapid ʻŌhiʻa Death‐affected Metrosideros polymorpha trees on Hawaiʻi Island" was just published in Forest Pathology!

This work investigated the presence and role of non-native amborsia beetles in releasing Rapid Ohia Death spores into the environment from infected trees

New paper by Gordon and Meng titled "Comparative genomics of a quadripartite symbiosis in a planthopper host reveals the origins and rearranged nutritional responsibilities of anciently diverged bacterial lineages" was just published in Environmental Microbiology!

This work extends our understanding of how bacterial symbioses have evolved in the planthoppers and throughout the Auchenorrhyncha. We were excited to use native Hawaiian insects to address fundamental questions of insect evolution and symbiosis.
