The vast majority of plant viruses are transmitted by insect vectors, with many crucial aspects the transmission process being mediated key protein–protein interactions. Still, very few vector proteins interacting have been identified and functionally characterized. Potato leafroll virus (PLRV) is most efficiently Myzus persicae, green peach aphid, in a circulative, non-propagative manner. Usin...

The green peach aphid, Myzus persicae, is globally distributed and an important pest of many economically valuable food crops, largely due to its ability transmit plant viruses. Almost all aphids, including M. carry the obligate symbiont Buchnera aphidicola, which provides essential amino acids that aphids cannot obtain from phloem plants themselves. Many also harbor facultative (secondary) end...

Oxylipins function as signaling molecules in plant growth and development and contribute to defense against stress. Here, we show that oxylipins also facilitate infestation of Arabidopsis thaliana shoots by the phloem sap-consuming green peach aphid (GPA; Myzus persicae), an agronomically important insect pest. GPAs had difficulty feeding from sieve elements and tapping into the xylem of lipoxy...
