A recent paper in PLoS One entitled Ionizing Radiation Changes the Electronic Properties of Melanin and Enhances the Growth of Melanized Fungi describes some pretty amazing results that have gotten some press lately. The lead author, Dr Dadachova, spoke on NPR’s Science Friday last [...]

From Genetics this week a review discusses Why are there still 1000 Uncharacterized Yeast genes? Poor Yeast – so many more genes have no known function, while S. pombe has nearly 100% coverage in functional annotation. I’ll also point out that the 1000 genes refers to protein-coding genes, not ncRNA genes which may mean that there is alot more that is [...] Lots of papers in Mycologia (subscription required) this month of different groups analyzing the fine-scale relationships of many different fungal clades using the loads of sequences that were generated as part of the Fungal Tree of Life [...] As announced at the Fungal Genetics meeting, the FGI at the Broad Institute is focusing on clusters of genomes rather than single ones. Some of genome projects are already grouped.
The genome of Pyrenophora tritici-repentis, the fourth sequenced Dothideomycete genome, was released by the FGI at the Broad Institute this spring (March 2007). P. tiritici-repentis was sequenced for its role as the cause of tan spot on wheat and as a research model for other Pyrenophora sp. that are pathogens of several grasses. The 6X assembly contains 37.8 Mb of sequence similar to the other [...] I read this blurb in the New Scientist about a PNAS paper (subscription required for next 6 months) on how hive beetles (Aethina tumida) are able to infest bee hives by throwing off the bees because they are producing isopentyl acetate which is thought to be produced and used by bees to signal an alarm.
