Dsrna As A Potential Tool For Cercospora Leaf Blight Management And Elucidation Of A Factors That Contribute To Late Disease Onset In The Reproductive Growth Stage Of Soybean, Marija Zivanovic
LSU Doctoral Dissertations
Cercospora leaf blight (CLB) of soybean (Glycine max L. Merr.), an important disease in Louisiana, is primarily caused by Cercospora cf. flagellaris. The pathogen produces cercosporin, a toxin necessary for fungal virulence. So far, there are few commercial cultivars of soybean with CLB resistance and few effective fungicides to manage this disease. Consequently, alternative management approaches are needed. With that in mind, the first objective was to develop a screening method to compare the effectiveness of bacterially-expressed double stranded (ds) RNAs corresponding to genes associated with cercosporin accumulation (Avr4, CTB1, CTB8, AY-1 and HN-2 …
Persistent Rna Viruses Of Common Bean (Phaseolus Vulgaris): Distribution And Interaction With The Host And Acute Plant Viruses, Surasak Khankhum
Persistent Rna Viruses Of Common Bean (Phaseolus Vulgaris): Distribution And Interaction With The Host And Acute Plant Viruses, Surasak Khankhum
LSU Doctoral Dissertations
Common bean (Phaseolus vulgaris) is the most important legume for direct human consumption. Common bean originated and was domesticated in the Americas but now is grown worldwide. As in the case of other crops, common bean can be infected with acute and persistent plant viruses. A modified dsRNA extraction method was developed and used in this study. The method was fast, economic, versatile, and required relatively small amounts of desiccated plant tissue. The method was successfully used to extract dsRNAs from plants infected with RNA plant viruses and to investigate the occurrence of two endornaviruses, Phaseolus vulgaris endornavirus 1 (PvEV1) …
