Grusz lab research, published in the October 2018 issue of Genome Biology and Evolution, uncovers a suite of mobile DNA sequences shaping plastome evolution in ferns. Collaborating with Utah State University (Paul Wolf, Tanner Robison), Duke University (Karla Sosa), and the Smithosonian Institution (Eric Schuettpelz), we generated genome skimming data to assemble and annotate 26 new chloroplast genomes from the fern family Pteridaceae.
Undergraduate researcher Blake Fauskee contributed his expertise to the identification of RNA editing sites across the newly generated chloroplast genomes. This interest stemmed from his time investigating the evolution of RNA editing in fern mitochondrial genomes (Field Museum REU, 2017).
Currently, the Grusz lab is examining the behavior of MORFFO elements in closely-related and/or sister species within the xeric-adapted genus Myriopteris. We look forward to sharing our findings soon!
