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

While transposable elements (TEs) are recognized as major drivers of fungal genome structure, evidence of their direct involvement in the interaction with host plants and the environment is only beginning to emerge. Retrotransposons can generate small RNA (sRNA) that act through cross-kingdom RNA interference, while giant DNA TEs called Starships carry dozens of cargo genes that enrich the accessory gene compartment of fungal genomes. In the polyphagous pathogen Botrytis cinerea, the Vv3...
