Genome mapping and DNA analysis are being used to
save animal and plant species around the world.

ASH TREE
In Europe,ash trees are under threat from the fungal
disease ash dieback,and from an invasive beetle called
the emerald ash borer.At the Royal Botanic Gardens,
Kew,scientists are analysing the genomes of ash trees,
searching for genes that confer resistance.The data will
be used to help breed disease-resistant trees.
GENOMIC ZOOS
Scientists aim to decode the genomes of vast numbers of
animal species to create enormous digital genomic zoos.
