ABC transporter genes ABC-C6 and ABC-G33 alter plant-microbeparasite interactions in the rhizosphere por Cox, D.E., Dyer, S., Weir, R., Cheseto, X., Sturrock, M., Coyne, D., Torto, B., Maule, A.G., Dalzell, J.J.

“…By inoculating selected differentially exuded compounds into control root exudates, we demonstrate that hexadecaonic acid and pentadecane are biologically relevant parasite repellents. ABC-C6 represents a promising target for breeding or biotechnology intervention strategies as gene knockdown leads to the repulsion of economically important plant parasites and retains attraction of the beneficial rhizobacterium B. subtilis. …”
