The DNA sequence of Melampsora larici-populina has been determined by the U.S. Department of Energy DOE Joint Genome Institute (DOE JGI). Annotations of the v1.0 assembly of Melampsora laricis-populina are publicly available at http://www.jgi.doe.gov/Melampsora.

Just noticed that the [[JGI]] has released the Cochliobolus heterostrophus genome sequence at their site predicting 9,633 protein-coding genes.  Torrey Mesa Research Institute had access to a sequence many years ago, but it isn’t until now that public version of this genome is available.  Cochliobolus is has been a model plant pathogen system and its production of T-Toxin by a PKS gene (Yang et al)

The [[Trichoderma reesei]] genome paper was recently published in Nature Biotechnology from Diego Martinez at [[LANL]] with collaborators at [[JGI]], [[LBNL]], and others. This fungus was chosen for sequencing because it was found on canvas tents eating the cotton material suggesting it may be a good candidate for degrading cellulose plant material as part of cellulosic ethanol production.

The 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.

The JGI have released the genome sequence and annotation of the Mycosphaerella fijiensis fungus an important crop pathogen of bananas. This Dothideomycete fungus is one of several in the clade of important plant pathogens that have been sequenced recently including M. gramicola, a relative that causes wheat-blotch.

I recently heard through the grapevine that the Mucor ircinelloides genome 4X assembly was completed by JGI and a BLAST server is available if you contact the authors. Mucorales (previously Zygomycota which is not monophyletic) includes previously sequenced Rhizopus oryzae and Phycomyces blakesleeanus which we’ve blogged about before.

Mucor is model system for the Zygos/Mucorales as it can be transformed

I’m including a recapping as many of the talks as I remember. There were 6 concurrent sessions each afternoon so you have to miss a lot of talks. The conference was bursting at the seams as it was- at least 140 people had to be turned away beyond the 750 who attended.

If there was any theme in the conference it was “Hey we are all using these genome sequences”.
