Aptamer‐mediated outer membrane destabilization overcomes low permeability resistance in Pseudomonas aeruginosa

open access: yesThe FEBS Journal, EarlyView.
DNA aptamers, Apt 60 and Apt 173, target the BamA protein to compromise outer membrane integrity in Pseudomonas aeruginosa, making it susceptible to Azithromycin, an antibiotic that is otherwise poorly effective due to the low‐permeability membrane.

Divergent roles of ent‐kaurene oxidase paralogs in rice momilactone biosynthesis

open access: yesJournal of Integrative Plant Biology, EarlyView.
Rice contains a five‐gene tandem array of genes encoding members of the ent‐kaurene oxidase (KO) family, with OsKOL4 and OsKOL5 playing divergent roles in momilactone metabolism, but both acting in the production of antifungal and antibacterial phytoalexins, which are important for disease resistance.
