Welcome to the ash dieback crowdsource wiki! In this wiki we aim to crowdsource information and genomic resources for Ash Dieback.

So far, the transcriptomes of four infected Ash samples have been sequenced and the transcriptome of unifected Ash:

  • 2 samples of infected Ash from Ashwellthorpe lower wood (The Sainsbury Laboratory)
  • 1 sample of infected Ash from Holt Country Park (The Sainsbury Laboratory)
  • 1 sample of infected Ash from Upton Broad and Marshes (The Sainsbury Laboratory)
  • 1 sample of uninfected Ash from Ashwellthorpe lower wood (The Sainsbury Laboratory)

The genome of a purified culture of Chalara fraxinea isolated from infected Ash collected at Kenninghall Wood has also been sequenced.
