Searching For Alternative Hosts And Determining The Variation In The Internal Transcribed Spacer (Its) Region Of Phakopsora Pachyrhizi And The Implications For Currently Used Molecular Diagnostic Assays: Subtitle, Tomas Allen Rush

LSU Master's Theses

Phakopsora pachyrhizi, the causal agent of soybean rust (SBR), is a serious disease on soybeans.The objectives of this project were to identify additional alternative and possible overwintering hosts of the SBR pathogen and to validate the current detection assays for SBR. For the first objective, we attempted to identify naturalized Louisiana legume(s) that can serve as hosts and overwintering sites for P. pachyrhizi. It was theorized that New Iberia and Iberville Parishes in south Louisiana are usually the first locations of soybean infection in the spring. This suggests that there may be alternative leguminous hosts located in these parishes that …
