Camelina Pathology

Molecular Diagnostic Tools for Detection and Differentiation of Phytoplasmas Based on Chaperonin-60 Reveal Differences in Host Plant Infection Patterns – T. Dumonceaux, M. Green, C. Hammond, E. Perez, C. Olivier – PLOS One 2014

Summary: Phytoplasmas (‘Candidatus Phytoplasma’ spp.) are insect-vectored bacteria that infect a wide variety of plants, including many agriculturally important species. The infections can cause devastating yield losses by inducing morphological changes that dramatically alter inflorescence development. We describe a method for accessing the chaperonin-60 (cpn60) gene sequence from a diverse array of ‘Ca.Phytoplasma’ spp. The oligonucleotide-coupled fluorescent microsphere assay revealed ...

Camelina Infected by Downy Mildew (Hyaloperonospora camelinae) in the Western United States: A First Report – M.L. Putnam and M. Serdani – Plant Management Network 2009

Summary: Poor flowering was observed in May 2009 on plants seeded in late September 2008. Symptomatic plants showed an abundant white woolly growth on the undersides of leaves and on stems. Link:

A New Report for Downy Mildew [(Hyaloperonospora camelinae Gäum.) Göker, Voglmayr, Riethm., M. Weiss & Oberw. 2003] of Camelina [Camelina sativa (L.) Crantz] in the High Plains of the United States – Harveson, R. M., Santra, D. K., Putnam, M. L., Curtis,

Summary: Camelina was recently introduced into North America, where it is currently grown commercially in Montana and North Dakota. During early June 2010, camelina plants from cultivar research trials began exhibiting downy mildew-like symptoms consisting of upper stem distortion and signs of white, fluffy masses covering stems, seed pods and heads. More investigation is warranted to determine whether these observations ...

Feeding behavior of a potential insect pest, Lygus hesperus, on four new industrial crops for the arid southwestern USA – S.E. Naranjo and M.A. Stefanek – Industrial Crops and Products 2012

Summary: The objectives of this study were to establish baseline data on the feeding behavior and potential impact of L. hesperus on camelina, guayule, lesquerella and vernonia. Results show that L. hesperus will readily feed on the economically important tissues of all crops, and although previous research has shown that this feeding did not consistently affect lesquerella yield, further work ...

Regional variation in Brassica nigra and other weedy crucifers for disease reaction to Alternaria brassicicola and Xanthomonas campestris pv. campestris – A.L. Westman, S.Kresovich, and M.H. Dickson – Euphytica 1999

Summary: In this study we evaluated 24 Eurasian crucifer species for disease reaction to North American isolates of the crop pathogens A. brassicicola and X. campestris pv. campestris. The test array comprised 190 entries (genebank accessions and weed populations), including 108 B. nigra entries from four geographic regions and 34 entries of Camelina sativa. Link:

Variation in Resistance of Camelina (Camelina sativa [L.] Crtz.) to Downy Mildew (Peronospora camelinae Gäum.) – J. Vollmann, S. Steinkellner, and J. Glauninger – Journal of Phytopathology 2001

Summary: An important low-input feature of camelina is its high level of resistance against plant diseases, which may partly be due to the production of antimicrobially efficient phytoalexins. In Central European countries such as Austria, downy mildew (Peronospora camelinae) is the only disease of camelina which has been found repeatedly, whereas other diseases and pests have been observed only occasionally. ...
