Emerging Genomics of Angiosperm Trees
Genome sequence assemblies of many angiosperm trees used in forestry are now emerging, in addition to the well-characterised genomes of black poplar and eucalyptus reviewed in previous chapters of this book. Whilst the number of published genomes of angiosperm forest trees lags behind that of angiosperm trees grown commercially for fruit or nuts, many new projects are underway. This is aided by the ever-decreasing cost of DNA sequencing technologies and has diverse motivations including tree improvement, ecological and evolutionary studies. In this chapter, we briefly review a number of recent whole genome projects including Chinese chestnut, European ash, dwarf birch, pedunculate oak, purple willow and shrub willow. We also describe new projects not yet in the public domain or with non-genomic data, and list various online resources where data and information can be accessed. We discuss potential future steps in improving genome assemblies, and the uses of such information in fields such as genomic selection to assist tree breeding.
