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.
http://apsjournals.apsnet.org/doi/abs/10.1094/PHYTO-97-7-0794
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.

Plant Disease is the leading
international journal for rapid reporting of research on new
diseases, epidemics, and methods of disease control.
Phytopathology is the premier international journal for articles
on fundamental research that advances understanding of the
nature of plant diseases, the agents that cause them, their
spread, the losses they cause, and measures that can be used to
control them.
Molecular Plant-Microbe Interactions (MPMI) is the
groundbreaking journal for publication of original, refereed
research on the molecular biology and molecular genetics of
pathological, symbiotic, and associative interactions of
microbes with plants and insects with plants. |
