Happy to share our work! 🍄🍇 Botrytis cinerea grapevine-specialized strains harbor a specific repertoire of transposons. While retrotransposon-derived small RNAs do not appear to play a significant role in virulence on grapevine, a new giant transposon—a #Starship— confers arsenic resistance.

📆 only one week left to register and make presentation proposals!
The recovery of #Puccinia graminis from aecia on #Berberis is nearing completion, with 36 samples collected in 2026 tested on a dozen grass and cereal species. Third year of data for Alicia Culot's PhD thesis, providing valuable information on primary hosts and formae speciales.
