Investigations Into Aspergillus Flavus Infection Of Corn And Regulation Of Aflatoxin Production By Volatiles And Biocontrol Strains, Rebecca R. Sweany
Investigations Into Aspergillus Flavus Infection Of Corn And Regulation Of Aflatoxin Production By Volatiles And Biocontrol Strains, Rebecca R. Sweany
LSU Doctoral Dissertations
Aspergillus flavus is an ascomycete fungus impacting agriculture, public and environmental health due to production of acutely-toxic, carcinogenic aflatoxins in oil seed crops, especially corn in Louisiana, and lung infections of immunocompromised patients resulting in a leading cause of AIDS patients’ deaths globally. The most effective aflatoxin mitigation strategy, biocontrol by atoxigenic A. flavus presents several concerns including: dissemination of a human pathogen, possible sexual reproduction and reliance on precise environmental conditions. Several aspects of A. flavus biology were investigated to potentially improve treatments. Studies investigated how genotypically diverse members within the A. flavus population interact with other population members …

A Survey Of Ballistosporic Phylloplane Yeasts In Baton Rouge, Louisiana, Sebastian Albu
LSU Master's Theses
A study documenting basidiomycete yeast biodiversity was conducted in Baton Rouge, Louisiana during 2010 and 2011. Using the spore-fall method, the leaf surfaces of seven ferns were sampled at biweekly intervals. Maximum likelihood phylogenetic analyses of the internal transcribed spacer (ITS) region and the D1/D2 domain of the large subunit (LSU) of nuclear ribosomal DNA were used to identify 463 isolates representing 81 species spanning 12 orders within six classes in Basidiomycota. Nearly 30 of these isolates appear to be species new to science. Data indicate fern leaf developmental stage has an effect on the number of yeasts present. A …
