Transformation of the host-selective toxin destruxin B by wild crucifers: probing a detoxification pathway – M.S.C. Pedras, S. Montaut, I.L. Zaharia, Y. Gai, and D.E. Ward – Phytochemistry 2003

Summary: This study shows that both Camelina sativa as well as Capsella bursa-pastoris are capable of metabolizing destruxin B, the host-specific toxin produced by the fungal pathogen A. brassicae during infection. Considering that C. sativa and C. bursa-pastoris detoxify destruxin B and produce the phytoalexins camalexins, these wild crucifers appear to represent unique and perhaps useful sources of black spot resistance in strategic plant breeding.
