East Tennessee State officially became a college in 1925 with a name change to East Tennessee State Teachers College. During this same time, East Tennessee State began applying for accreditation from the Association of Colleges and Secondary Schools of the Southern States. The institution would eventually achieve accreditation in 1927. This is a hand written draft of an early accreditation application completed in 1925 by President Charles C. Sherrod, of whom the current ETSU main campus library is now named. The physical copy of this item can be found in the President Correspondences Collection of the Archives of Appalachia at East Tennessee State University. For access or more information please contact the Archives of Appalachia.

I will describe a variety of summer initiatives housed at the ETSU Center of Excellence in Mathematics and Science Education. These include the Eastman MathElites Program; the Niswonger Mathletes Program; Improving Teacher Quality Projects; the Tennessee Governor’s School; and State MSP Projects. Most importantly, though, I will describe efforts, via Battelle and State funding, to enable HS students to incorporate open source coding into their math classes.

Iron is extremely important for many organisms. Despite its abundancy, it exists in insoluble forms that makes its usability difficult. Some organisms secrete siderophores, low molecular weight compounds, that can chelate iron and convert it into usable forms for cells. One such organism, Rhizobium leguminosarum, is a nitrogen fixing symbiont proteobacteria that infects leguminous plants. The genome of Rhizobium leguminosarum ATCC 14479, which infects the red clover, Trifoli pratense, has previously been completely sequenced in our lab. Our lab has identified several genes in this strain involved in the biosynthesis of a siderophore, vicibactin. The protein product of one of those genes, VbsS, is hypothesized to be a non-ribosomal peptide synthase. It has been attempted to knockout the VbsS gene utilizing the ‘splicing by overlap extension’ method. Additionally, an in-silico analysis of the genome revealed the Vbs genes in R. leguminosarum ATCC 14479 strain were similar to genes in found in the proteobacterium Phyllobacterium sp. 628 and the fungi Aspergillus fumigatus Af293.
