Jeremy Schmutz from the JGIs Genome Assembly Group has provided a summary report jgisummary.pdf
The H97 assembly will change when the remainder of the sequence is generated and reassembled. Contig and scaffold numbers and arrangements will change between the 4X and 8X assembly and the JGI does not provide read mapping information.
ESTs for Agaricus bisporus U1 are currently in clustering.
The JGI remain interested in any resources our community has to offer to aid in the annotation, e.g. ESTs, BAC libraries, physical and genetic maps. If research groups have suitable resources and would be prepared to share them with the project, please let me know as soon as possible.
