Role Of Kinases And An Epigenetically Regulated Gene In Soybean Cyst Nematode Resistance, Tracy Elizabeth Hawk May 2023

Role Of Kinases And An Epigenetically Regulated Gene In Soybean Cyst Nematode Resistance, Tracy Elizabeth Hawk

Doctoral Dissertations

Soybean cyst nematode (SCN) is the most devastating and economically important pathogen of soybean across the United States and globally. The current primary control for SCN is with the use of resistant cultivars, however, SCN populations are shifting to overcome most common sources of soybean resistance. This research was conducted to identify novel sources of genetic resistance to SCN. First, I functionally characterized two protein kinase hub genes whose function are predicted to be essential for mediating soybean susceptibility to SCN. I generated kinase-dead variants by mutating two amino acids required for the kinase enzymatic activity. Overexpression of the kinase-dead …


Fungicide Sensitivity Screening Of Corynespora Cassiicola In Us Soybean And Cotton, Tyler Miles Smith May 2021

Fungicide Sensitivity Screening Of Corynespora Cassiicola In Us Soybean And Cotton, Tyler Miles Smith

Doctoral Dissertations

Target spot, caused by the fungus Corynespora cassiicola, is a foliar disease of cotton and soybean. Target spot has become a disease of concern in soybean and cotton production systems. Data for fungicide sensitivity and understanding potential impact on yield is lacking for C. cassiicola. Fungicide resistance is also a concern in C. cassiicola with the increase in resistant pathogens in soybean. With the lack of knowledge about baseline fungicide sensitivity and the concern of fungicide resistance the objectives of this study were: (i) to evaluate fungicide products and mixes in small plot soybean and cotton trials, (ii) …
