[Coral-List] Coral genome sequence assembled

This isn't an apples to apples comparison.  Immediately after the human 
genome was completed, people were claiming numbers almost 2x higher than 
the (somewhat) accepted number for humans today.  I suspect that most of 
these gene calls have been made automatically, and that the number of 
actual genes in Acropora will be somewhat lower than is currently claimed. 
Ditto for Daphnia.

However, I am very happy that a coral genome has been sequenced.

The genome assembly is the result of a collaboration between the Australian Genome Research Facility (AGRF) and The ARC Centre of Excellence for Coral Reef Studies at James Cook University (JCU) but also involved some of the brightest and best of the Australian bioinformatics community.

This assembly is based exclusively on short (75-100bp) Illumina reads (GA IIx and HiSeq) from paired end (160 to 580 bp) and mate pair (2200 to 10000 bp) libraries. A variety of tools were used for the assembly, including libngs (https://github.com/sylvainforet/libngs), Nesoni (http://bioinformatics.net.au/software.nesoni.shtml), and a modified Velvet assembler (https://github.com/sylvainforet/velvet). The genome is approximately 400 Mb and contains around 25,000 genes. The N50 of the assembly is about 170 kb, and coverage about 80x.
