Congrats to Divya and Jason as our paper with collaborators Hugo Melida and Vincent Bulone: Deciphering the uniqueness of Mucoromycotina cell walls by combining biochemical and phylogenomic approaches is now available at Environmental Microbiology. We discovered in this work that two Mucormycotina species have novel fucose sugar composition in their cell walls which is not found in other Fungi. We also identify expansions and unique subfamilies of Chitin synthase genes.
Steven and Jason attended the Mycological Society of America’s 2014 conference in East Lansing, MI. This included coming in a day early enough for some of us to go on the foray on Sunday after we attended the Microbiology of the Built Environment conference in Boulder, CO.
MSA2104 was a great chance to catch up with friends and colleagues and hear some excellent talks on the current state of research in the fields of systematics & taxonomy; ecology & pathology; genetics & molecular biology. Genomics pervades a lot of the research where it was not quite part of the picture when I first started attending so it was great to see how many people taking advantage of the amazing resources produced by the JGI sequencing programs. I also really enjoyed the Karling lecture from Bruce McDonald on domestication in fungi and plants and the “dark side” of this domestication (meaning mostly that there are unintended consequences).
There was some tweeting going on at the meeting – I tried to capture some with a storify available here.
Jason presented research on the evolution of the fungal cell wall examining early diverging lineages of fungi which is the work of former graduate student Divya Sain.
Steven presented his poster on the inhibitory properties of a Chytridiomycota fungus we work on that affects growth of some filamentous fungi and won the award for best graduate student poster!
Jason was also honored with the 2014 Alexopoulos Prize to honor a young Mycologist. The prize is in memory of C. J. Alexopoulos who among other things authored the great Introductory Mycology textbook. I have not yet decided how I will spend the prize money but I intend to support a project in the lab or to support travel for collecting more strains tied to chytrid work.

We published a paper on the manual curation of the literature for the Cryptococcus complex of species (C. neoformans var neoformans, C. neoformans var grubii, and C. gattii) this includes associated gene names with systematic locus names, something that was not easy to lookup without reading the published literature. In all more than 600 loci had gene names associated with them and include updated Gene Ontology associations, gene product names and descriptions and a table of orthology relationships between the genes in the different species genomes.
The early access to the paper is available was released at Eukaryotic Cell in May and includes guidelines of how the community can go forward naming genes in these species. In addition we make available a table of these names available at FungiDB at this link. And future updates are being posted through GitHub so that community contributions can happen directly through edits to the file or through the comments section at FungiDB where comments can be added by any user indicating a gene name and these will be evaluated and curated by a Scientific Curator.
This work was done my a lot of hard work from Diane Inglis and Marek Skrzypek who are scientific curators at (Stanford University) under the direction of Gavin Sherlock and the gene names and descriptions are loaded and available in FungiDB through the work of Ed Liaw and Venky Moktali at UC Riverside. We were able to do this work through an NIH R03 grant and look forward to finishing the complete literature curation by the end of this year.
We congratulate Divya on defending her dissertation on “Discovery of fungal cell wall components using evolutionary and functional genomics”. Her last revisions and formatting is taking place and she should be the first minted PhD from the Stajich lab before Christmas. We are happy and proud of her accomplishment to complete this important milestone!
We are happy to welcome Dr Ousmane Cisse to the lab to work on evolution of multicellularity in Fungi. He will primarily focus on comparative genomics and evolution of filamentous fungal growth in the fungal kingdom, examining the genome of Neolecta and taking advantage of data from the 1000 fungal genomes project and other data sets. He joins us after completing his PhD at the University of Lausanne in Switzerland. He focused on comparative genomics of several Taphrinamycotina fungi and will continue this theme working on Neolecta. He was awarded a prestigious early postdoc mobility fellowship from the Swiss National Science Foundation Fellowship.
Today was the presentations from UCR RISE summer program and undergraduate student Na Jeong showed her work on studying the inhibitory properties of the H. polyrhiza species of chytrid on several Ascomycete fungi. She was mentored by Steven Ahrendt in the lab who first made this observation. Here is Na presenting her work and with Jason and Steven.
We’re excited that several manuscripts were published in the last month.
One presents the first genome from the Cryptomycota, Rozella allomycis, in a manuscript published in Current Biology along with a nice companion piece from Mark van der Giezen about the work. Steven and Divya participating in this project in collaboration with Tim James at Michigan and Nico Corradi in Montreal. Some of the scripts used for this project are available as well here on github and other associated genome data are available here. We are working to get this into the next FungiDB release as well.
A manuscript from Andrii Gryganskyi who was a lab visitor last summer was published on the Entomopthorales fungus Entomophthora muscae.
A review on the application of genomics to mycology was published in Mycologia celebrating the new era of mycology and the first genome sequences published in this journal.
Work from Anastasia Gioti, who was a lab visitor for several months this year and has visited several times in the past years, wrapped up genome comparisons of Neurospora species which have transitioning from outcrossing (heterothallic) to self-fertile (homothallic) lifestyles. Our manuscript was made available in Evolution this summer and will be published in the Fall.
A paper on the population genomics of amphibian killing chytrid fungus B. dendrobatidis that culminated several years of work and large collection of researchers was published in PNAS at the beginning of the summer.
We headed over to Lake Perris for a lab BBQ and fun afternoon in the sun. Here’s a few pictures of the group all together.
Congrats to the lab for a great Fungal Genetics meeting. Everyone was participating in the meeting, presenting their work, and hearing about the new things coming out in other research laboratories. Was exhausting pace with 8AM to 10 PM (or later) every day but I think the fun and science excitement overshadowed the tiredness. Congratulations to Steven who won a poster prize and to Jason for his election to the Fungal Genetics Policy Committee. FungiDB was demoed in a workshop and poster sessions and we seemed to get a lot of interest and feedback along with the excellent presentation by Omar Harb from the EuPathDB team to lead the workshop.
We will post some pictures and upload our poster PDFs in the coming weeks I expect, still catching up on sleep and reengaging in our research after that.
Thanks to all who came by to talk with us at our posters and it was great fun to make new friends and reconnected with long-time ones.
We had a little celebration to recognize Steven passing his qualifying exam this week.
