Researchers completed a telomere-to-telomere genome assembly for the fungal plant pathogen Botrytis cinerea strain B05.10.

What it means

Researchers have completed a telomere-to-telomere genome assembly for Botrytis cinerea strain B05.10, meaning the entire genome of this fungal plant pathogen has been sequenced from one end of each chromosome to the other with no gaps. This strain is a widely used reference isolate in labs studying gray mold disease. The assembly provides a complete and gapless reference genome, which will improve genetic and genomic studies of this pathogen.

Accuracy & sourcesGrounded

The claim is based directly on a bioRxiv preprint, which is a primary source but not yet peer-reviewed. The preprint itself presents the assembly, so the claim is accurate as a description of its content.

How new

This is genuinely new material, published as a preprint on October 20, 2026 and reported on October 25, 2026.
