Role of transposons in the specialization of Botrytis cinerea to grapevine: Insights into small RNAs and a new Starship

Antoine Porquier, Adeline Simon, Justine Vergne…·Muriel Viaud

This study investigates the role of transposons in Botrytis cinerea's adaptation to grapevine, identifying a new Starship transposon that confers arsenic resistance.

Botrytis cinerea strains infecting grapevine and tomato display contrasted repertoires of accessory chromosomes, transposons and small RNAs

Adeline Simon, Alex Mercier, Pierre Gladieux…·Muriel Viaud

This study compares genomic features of Botrytis cinerea strains from grapevine and tomato, finding differences in accessory chromosomes, transposons, and small RNAs associated with host specialization.
