B. dendrobatidis strain JAM81 released

B.dendrobatidis zoosporeThe following is an announcement to the B.dendrobatidis and fungal community at large from Alan Kuo at JGI. This is the JAM81 strain (Jess Morgan collected from a frog in the California Sierra Nevada). The JEL423 (Joyce Longcore, collected in Panama) strain genome sequence and annotation is available from the Broad Institute.

Please do contact me if you would like to contribute to assigning functions to the annotation. We’re in the last round of analyses for some of the genome work, but if there are particular questions you want to contribute to, we’re open to collaborators and can outline the basis of our work to see how other work can complement it.

From Alan Kuo at JGI:

The JGI Batrachochytrium annotation portal is now on the public JGI website. As it is public, no password is required.

For those of you who have not yet registered to be an annotator, go to this new link to register.As before, please choose a username that is personal, so that other annotators may be able to recognize it as yours. A derivative of your personal name would be best.

Those of you who are already registered, you do not need to do anything. Your old pre-release username and password are valid on the new public portal too.

As always, please direct all questions and problems to me. Use email or phone: Cheers, Alan.

Some information about the assembly and annotation:

The first annotation of the 127 scaffolds and 24 Mbp of JGI’s 8.74X assembly of the Batrachochytrim dendrobatidis JAM81 genome. We predict 8732 genes, with the following average properties:

Gene length 1825.16 nt
Transcript length 1407.29 nt
Protein length 450.56 aa
Exon frequency 4.29 exons/gene
Exon length 328.37 nt
Intron length 129.18 nt
Gene density 359.1 genes/Mbp scaffold

The genes were found by the following methods:
Total models 8732 (100%)
Jason’s models 3214 (37%)
cDNAs and ESTs 518 (6%)
Similarity to nr 1928 (22%)
ab initio 3072 (35%)

The genes were validated by the following evidence:
start+stop codons 7990 (92%)
EST support 2488 (28%)
nr hit 6787 (78%)
Pfam hit 4329 (50%)

Ectomycorrhizal fungus Laccaria bicolor genome

Today, I would like to share the news about the publication of the Laccaria bicolor genome. This is the first mycorrhizal symbiotic genome published in the Nature journal. The title is “The genome of Laccaria bicolor provides insights into mycorrhizal symbiosis”.

The team consisteing of more than 60 researchers from 16 institutions have revealed the interaction between plant and fungi.
