TGAC releases new genetic data to combat ash dieback epidemic

The Genome Analysis Centre (TGAC) has released new genetic data that will help understand the spread of the ash dieback epidemic, across Europe and the UK. As part of the  NORNEX consortium , TGAC has sequenced 20 genomes of the fungus ( Hymenoscyphus fraxineus ) responsible for the spread of the ash dieback epidemic that threatens our third most common broadleaf tree (after oak and...

Ash dieback fungus may have mechanism to define territory and to combat viruses

The fungus which causes Chalara dieback of ash trees has the potential to defend itself against virus attacks, research by British scientists has shown. Plant pathologists Dr Joan Webber, from Forest Research, the research agency of the Forestry Commission, and Professor Clive Brasier found that the defence mechanisms which the  Chalara fraxinea (C. fraxinea)  fungus uses to...

New study offers hope for halting incurable citrus disease

The devastating disease Huonglongbing, or citrus greening, looms darkly over the United States, threatening to wipe out the nation's citrus industry, whose fresh fruit alone was valued at more than $3.4 billion in 2012. Recently, however, a research team led by a University of California, Davis, plant scientist used DNA sequencing technologies to paint a broad picture of how citrus...

Ash dieback surviver's genome sequence could aid breeding of disease tolerant trees

The genome of an ash tree that has survived ash dieback disease has been sequenced by scientists from The Genome Analysis Centre (TGAC) and made publicly available via    OpenAshDieBack . Tree 35, from the Danish island of Zealand, was identified as having high levels of resistance to the Chalara fraxinea fungus which causes ash dieback. It is hoped that this...
