Genome Sequence of the Bacteriophage Eugenia.

We report the discovery and genome sequence of mycobacteriophage Eugenia, isolated from soil samples collected in Akron, OH. Eugenia is a double-stranded DNA virus with a genome size of 69,139 bp, featuring 104 predicted protein-encoding genes, with 32 of these genes assigned putative functions.

Overaccumulation of γ-Glutamylcysteine in a Jasmonate-Hypersensitive Arabidopsis Mutant Causes Jasmonate-Dependent Growth Inhibition.

Glutathione (GSH) is essential for many aspects of plant biology and is associated with jasmonate signaling in stress responses. We characterized an Arabidopsis (Arabidopsis thaliana) jasmonate-hypersensitive mutant (jah2) with seedling root growth 100-fold more sensitive to inhibition by the hormone jasmonyl-isoleucine than the wild type. Genetic mapping and genome sequencing determined that the mutation is in intron 6 of GLUTATHIONE SYNTHETASE2, encoding the enzyme that converts γ-glutamylcysteine (γ-EC) to GSH.
