It’s a high-quality draft (8x coverage) sequenced at the JGI – they have a press release and a page of data for this genome. It’s a good paper – they’ve done a thorough analysis of the available data. Although one-sixth the size of the human genome, this tree has around twice as many protein-coding genes. There’s also evidence for at least two genome duplication events in its history – not uncommon in plants, many of which are polyploid. This is only the third published plant genome after Arabidopsis and rice – I’d like to see many more.
