Evolution of the Neopsylla hongyangensis Mitogenome: Insights Into the Mitogenomic Evolution of the Orders Siphonaptera and the Phthiraptera

open access: yesEcology and Evolution, Volume 15, Issue 3, March 2025.
The Neopsylla hongyangensis is an important medical insect that transmits plague. We sequenced the mitogenome of N. hongyangensis and constructed a phylogenetic tree for the order Siphonaptera. In addition, we explored the mitogenomic evolution of the orders Siphonaptera and Phthiraptera, which both belong to the class Insects, on warm‐blooded animals ...

Hymenopteran‐specific TRPA channel from the Texas leaf cutter ant (Atta texana) is heat and cold activated and expression correlates with environmental temperature

open access: yesInsect Science, Volume 32, Issue 1, Page 301-320, February 2025.
Texas leaf cutter ant (Atta texana) populations have expanded northward and their obligate symbiotic fungus has increased cold tolerance. The ants have exquisitely temperature sensitive antennae; here, we find the antennae express a subset of six transient receptor potential (TRP) channels, including HsTRPA.

Chemical Tools for Probing the Ub/Ubl Conjugation Cascades

open access: yesChemBioChem, Volume 26, Issue 1, January 2, 2025.
Post‐translational modification by ubiquitin (Ub) and ubiquitin‐like proteins (Ubl) regulate a diverse array of cellular pathways. Ub/Ubl conjugation is orchestrated by a cascade of specialized E1, E2, and E3 enzymes. Here, we review chemical tools and methods implemented to probe enzymatic activities and to capture and characterize fleeting chemical ...
