Glycoside Hydrolase Gene Families Of Termite Hindgut Protists
Of those families examined, the results are broadly consistent with Todaka et al. 2010, though none of the GHFs found were expressed in both termite-associated protist and non-termite-associated protist transcriptome data. This suggests that, rather than being inherited from their free-living protist ancestors, GHF genes were acquired by termite protists while within the termite gut, potentially via lateral gene transfer (LGT). For example one family, GHF10, implies a single acquisition of a bacterial xylanase into termite protists. The phylogenies from GHF5 and GHF11 each imply two distinct acquisitions in termite protist ancestors, each from bacteria. In eukaryote-dominated GHFs, GHF7 and GHF45, there are three apparent acquisitions by termite protists. Meanwhile, it appears prior reports of GHF62 in the termite gut may have been misidentified GHF43 sequences. GHF43 was the only GHF found to contain sequences from the protists not found in the termite gut. These findings generally all support the possibility termite-associated protists adapted to a lignocellulosic diet after colonization of the termite hindgut. Nonetheless, the poor resolution of GHF phylogeny and limited termite and protist sampling constrain interpretation.]]>autSanderlin, ViolathsGile, Gillian HdgcWojciechowski, MartindgcWeiss, TaylordgcVarman, Arul MozhypblArizona State UniversityengMasters Thesis Biological Design 2019https://hdl.handle.net/2286/R.I.5496000Masters ThesisAcademic theses82 pages115730764821630032421157712adminIn Copyright2019TextBioinformaticsglycoside hydrolasemetagenomemetatranscriptomePhylogeneticsprotistTermites
