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

           HIGH-TECH CONSERVATON

           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.
