Nanhu News (Correspondent Yang Fuxiang) Recently, Professor Wang Manyu from the School of Plant Science and Technology of our school led the insect chemical ecology team to publish a research paper entitled "Sublethal Exposure to Cadmium Induces Chemosensory Dysfunction in Fire Ants" in "Environmental Science & Technology.
The red fire ant (Solenopsis invicta Buren) is one of the 100 most destructive invasive species in the world listed by the International Union for Conservation of Nature (IUCN.
Cd is considered to be an olfactory poison in animals, but the molecular mechanism by which Cd affects the olfactory function of animals is still unclea.
Cd exposure induces the expression of SiOBP15 protein in the antennae of RIFA workers
The researchers further analyzed the binding properties of SiOBP7 and SiOBP15 proteins to 22 RIFA food-derived odor molecules, and found that SiOBP7 and SiOBP15 proteins were associated with limonene, nonanal and 2,4,6-collidine ( 2,4,6-trimethylpyridine) have strong binding abilit.
Cd pollution alters the expression of OBPs in the antennae of RIFA workers and interferes with their recognition of odorants
Yang Fuxiang, a 2019 graduate student of the School of Plant Science and Technology, is the first author of the paper, and Associate Professor Zhou Aiming is the corresponding author of the pape.
