Taxonomic And Genetic Diversity, And Pathogenicity Of Diaporthe Species Associated With Soybean, Fakhir Eraheem Hameed Al Shuwaili Jul 2020

Taxonomic And Genetic Diversity, And Pathogenicity Of Diaporthe Species Associated With Soybean, Fakhir Eraheem Hameed Al Shuwaili

Graduate Theses and Dissertations

Diaporthe species (anamorph: Phomopsis) are associated with a wide range of plant hosts as plant pathogens, asymptomatic endophytes, and saprobes. One of these hosts is soybean, which is one of the most important crops in U.S. agriculture. Several Diaporthe species cause important diseases on soybean in the U.S., and specifically in Arkansas. The taxonomy, genetic diversity, and pathogenicity of Diaporthe species associated with asymptomatic infection of soybean are rarely studied with accurate molecular tools. Therefore, this dissertation aimed to assess the diversity and boundaries of Diaporthe associated with soybean in Arkansas. Furthermore, pathogenicity and alternative lifestyles were assessed among Diaporthe …


Dissecting The Cellular Control Of Septin Organization In A Global Cereal Killer, Nawaraj Dulal Jul 2020

Dissecting The Cellular Control Of Septin Organization In A Global Cereal Killer, Nawaraj Dulal

Graduate Theses and Dissertations

Rice blast disease, caused by the filamentous fungus Magnaporthe oryzae, destroys sufficient rice each year to feed 60 million people, and is a serious threat to global food security. A wheat-adapted lineage of M. oryzae now poses threat to global wheat production. Rice blast disease is currently controlled using limited fungicides, and the emergence of fungicide resistance within M. oryzae populations is a growing concern. There is a pressing need to identify new classes of fungicides to control the disease, which requires better understanding of the basic biology of the pathogen. To establish disease, M. oryzae forms a specialized dome …
