Bring on the Panicoids!

No, not Panic-oids. The Panicoids, or members of the grass subfamily Panicoideae, include important crops such as corn, sorghum, and sugarcane. We have published a phylogenomic estimate of Panicoid relationships in the journal BMC Plant Biology. This represents the completion of our first genomic-level phylogenies for each of the four giant subfamilies of grasses. The paper is a nice feather-in-the-cap for lead author Sean Burke, a student in Mel Duvall's lab. Well done, Sean!

Mar 2016 New evolutionary tree for Chloridoid grasses

What kind of grass thrives in hot arid regions? A Chloridoid! These tough little plants use a special kind of photosynthesis called C4, which allows them to better handle heat, drought, and low CO2 levels. Our new paper uses genomic data to propose a chloroplast phylogeny estimation of the subfamily Chloridoideae. Lead author Mel Duvall and specialists Travis Columbus and Amanda Fisher have combined their expertise to finish this nice collaborative project. More to come!

Oct 2015 Molecular Homology Gets A New Definition

A much needed framework for assessing molecular homology is now published. The paper, by David Morrison, Matt Morgan, and Scot Kelchner, synthesizes nearly three decades of ideas about the nature of homology at the nucleotide, gene, and protein levels. Our new definitions could help improve the automated alignment of DNA sequences and the evolutionary analysis of genomic data. Or it might not. We'll see! 

Jul 2014 Genealogical Networks, Leiden, Netherlands

Dr. Kelchner gives an invited talk in the Netherlands, at the meeting "Genealogical Phylogenetic Networks in Evolutionary Biology". It was pleasant to be back at Leiden University. Particular thanks go to David Morrison, Axel Janke, Céline Scornavacca, Jim Whitfield, and Mike Steel for their pleasant company and impressive tolerance of Kelchner's giardia and entamoeba infections. That's real friendship.
