July 2007 Spotlight Articles Selected by the Editors of Plant Disease, Phytopathology, and Molecular Plant-Microbe Interactions (MPMI) Plant Disease Editor’s Pick Rhizomania is a serious, widespread disease of sugar beet caused by Beet necrotic yellow vein virus. In the July issue of Plant Disease, an article reports that resistance-breaking strains of the virus were found for the first time in multiple states west of the Mississippi. Phytopathology Editor’s Pick The induction of systemic acquired resistance (SAR) has long been viewed as a means to obtain broad-spectrum resistance. The results have been mixed. The July Editor’s Pick in Phytopathology reports that induction of SAR in canola with BTH confers resistance to a bacterial and fungal pathogen, and that this was associated with upregulation of PR genes in a salicylic acid-dependent manner. MPMI Editor’s Pick Several plant pathogenic fungi and bacteria produce plant hormones. In the July issue of MPMI, an article explains that the Gram-positive bacterium Streptomyces turgidiscabies has a functional cytokinin (CK) operon and can cause characteristic galls on plants. The CK operon is on the same mobilizable pathogenicity island that contains multiple virulence genes. An online subscription is needed to access the full articles.
