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 to Flea Beetle Phyllotreta cruciferae (Coleoptera: Chrysomelidae) in False Flax, Camelina sativa (Brassicaceae) — P. Pachagounder, R.J. Lamb, and R.P. Bodnaryk – The Canadian Entomologist 1998

Summary: Feeding damage by the crucifer flea beetle, Phyllotreta cruciferae, was assessed on 51 accessions of false flax, Camelina sativa, and compared with damage to seven other crucifer species. Flea beetles were observed sitting on false flax in the field, sometimes in high numbers, but they did not feed. Resistance in false flax may result from the absence of cues ...

Phytoplasma diseases and their relationships with insect and plant hosts in Canadian horticultural and field crops – C.Y. Olivier, D.T. Lowery and L.W. Stobbs – Can Entomol 2009

Summary: In Canada, seven phytoplasma taxa have been detected in various crops. Aster yellows, the primary vector of which is the leafhopper Macrosteles quadrilineatus, is the most common and widespread. Ash yellows and pear decline have caused economic problems for several decades, while bois noir, a quarantinable disease in Canada, was detected in Ontario and British Columbia for the first ...

Intergeneric protoplast fusion between Brassica carinata and Camelina sativa – S.B. Narasimhulu, B.Kirti, S.R. Bhatt, S. Prakash, and V.L. Chopra – Plant Cell Reports 1994

Summary: Camelina sativa is a wild crucifer that is reported to be resistant to Alternaria blight. In order to transfer Alternaria resistance to B. carinata, fusion of protoplasts of the two species was performed. Confirmation of hybridity was obtained from the morphology of in vitro produced leaves, somatic chromosome number in leaf tips, and restriction fragment length polymorphism for a ...

Resistance to Rhizoctonia solani and Presence of Antimicrobial Compounds in Camelina sativa Roots – K.L. Conn, L.M. Browne, J.P. Tewari, and W.A. Ayer – Journal of Plant Biochemistry and Biotechnology 1994

Summary: This appears to be the first report of elicitation of phytoalexins from roots of crucifers. Additionally, two preformed antimicrobial compounds were identified as methyl 1-methylindole-3-carboxylate and 10-methyl sulfinyldecylisothiocyanate. Link:
