Overexpression of the 14[alpha]-demethylase-target gene (CYP51) mediates fungicide resistance in Blumeriella jaapii
Article Abstract:
Resistance to demethylation inhibitor (DMI) is mediated either through alterations in the structure of the target enzyme CYP51 (encoding 14alpha-demethylase), through increased expression of the CPY54 gene, or through increased expression of efflux pumps. The analysis of sequences upstream of CPY51 in 59 DMI isolates revealed that various forms of a truncated non-long terminal direct repeat long interspersed nuclear element retrotransposon were present in all instances.

Effect of solar UV-B radiation on a phyllosphere bacterial community
Article Abstract:
Solar UV-B radiation can change the microbial populations on the surface of a leaf. In a study of peanut leaves, plants exposed to UV-B had a greater percentage of UV-tolerant bacteria than plants not exposed to UV-B. Bacillus coagulans, Clavibacter michiganensis, and Curtobacterium flaccumfaciens were the predominant UV-tolerant bacteria.

Genetic differences between blight-causing Erwinia species with differing host specificities, identified by suppression subtractive hybridization
Article Abstract:
A study identified genomic differences among plant-pathogenic Erwinia strains. The experiments resulted in the identification of strain-specific sequences including genes encoding a putative type-II secretion system (T3SS) effector, a T3SS apparatus components, and several putative membrane proteins.
