UCR talk, 13th Sept 2012
Transcript of UCR talk, 13th Sept 2012
2. Placement among early diverging fungi
3. Broader phylogeny
4. Mol. phylogeny vs. morphology & ultrastructure
5. Ancestral state reconstruction
6. Divergence time Outline other fungi flagellates ENTOS Materials & methods ~20 isolates, 4 loci
AFToL data, GenBank for ~40 more taxa of Entos, ~20 chytrids, ~100 zygomycetes
38 non-molecular characters
ML, BI, MP and common sense
GARLI, RAxML, MrBayes, Mesquite, PAML, BEAST (and Beauty) SHAPE OF CONIDIA
- ovoid, pyriform MONOPHYLETIC
Kickxellomycotina - sister group, no any flagellates
5 major lineages
time of origin ~405 MYA
ancestor - Conidiobolus-like Conclusions TO EVERYBODY, even if they did not helped!
Particularly: to Rytas for everything, Blanka Shaw for help with database, Katalin Molnar and Bernie Ball for PCR and reagents, Carl Rothfels and Nimrod Rubinstein with substitution rates analysis, Michelle Gignac for SEM and TEM; Meredith Blackwell, Gregory Bonito, Jason Jackson, Anastasia Litvintseva, François Lutzoni, Marianela Rodrigues-Carres, Sujal Phadke and David Swofford for essential discussion, Bradley Mullens for insect identification, Tim James, Bo Huang, Kathie Hodge and Yan Wang for the sequences, Jason Stajich, Steven Ahrendt and Sofia Robb for programming and lots of other stuff. Thankfulness Andrii Gryganskyi and many other good people A. B. Jensen and J.

1) less number of copies,
3) change of function?. Dynamics of fly infection occurrence, March-May 2012. Blue arrows - rains, red cross – end of epizooty.
