Identifying Genetic Sources Of Anthracnose Resistance In Global Sorghum Lines, Mary-Frances Behnke
All Theses
Anthracnose of sorghum (causal agent: Colletotrichum sublineola) is the most detrimental disease of sorghum (Sorghum bicolor) worldwide, significantly reducing grain yield. This study includes a literature review of the disease and a meta-analysis of genome-wide association studies (GWAS) of anthracnose-resistance in sorghum as means to elucidate genetic sources of the trait. The meta-analysis includes genotypic and phenotypic data from 5 unique studies and 1,071 sorghum lines. Original genotyping-by-sequencing data from were obtained primarily from National Center for Biotechnology Information’s Sequence Read Archive (NCBI-SRA) and prepared and processed using the Tassel 5 GBS v2. pipeline. Phenotypic data were …

The Presence And Distribution Of Crotoxin In The Rock Rattlesnake (Crotalus Lepidus), Jade Mellor
All Theses
Crotoxin and its homologs (hereafter all referred to as CTx) is a highly lethal heterodimeric beta-neurotoxin found in pitvipers (Crotalinae) and is the main driver of neurotoxic venom phenotypes (Type II). In contrast, hemorrhagic venom phenotypes (Type I) are characterized by high snake venom metalloproteinase expression and low toxicity. Although many rattlesnake species have been classified as either Type I or Type II, population level variation in venom phenotype has also been documented in several species. The presence or absence of CTx is the main component of this variation in venom phenotype and has been most widely studied in large-bodied …
