Phytophthora Sojae Infecting Soybean: Pathotype Diversity, New Sources Of Resistance And Interaction With The Soybean Cyst Nematode, Rawnaq Nazneen Chowdhury
Phytophthora Sojae Infecting Soybean: Pathotype Diversity, New Sources Of Resistance And Interaction With The Soybean Cyst Nematode, Rawnaq Nazneen Chowdhury
Electronic Theses and Dissertations
Phytophthora root and stem rot, caused by Phytophthora sojae Kaufmann and Gerdemann, is an important disease of soybean (Glycine max L.) in South Dakota. To gain a better understanding of the importance of P. sojae in South Dakota, specifically pathotype diversity, identification of new resistance sources and the interaction with the soybean cyst nematode (Heterodera glycines Ichinohe, SCN), this research was undertaken with the following objectives - 1) to characterize the pathotype diversity of P. sojae causing Phytophthora root and stem rot on soybean in commercial fields in South Dakota; 2) to compare inoculation methods to evaluate for …

Regulation Of Arf16-2 By Microrna160 During Soybean Root Nodule Development, Spencer Schreier
Electronic Theses and Dissertations
Soybean is an excellent candidate for sustainable agriculture due to its production of nutritious, versatile beans and the ability to form symbiotic organs called root nodules that perform nitrogen fixation. As demand for both yield and sustainable agriculture continue to increase, root nodules offer an attractive alternative to expensive and environmentally harmful nitrogen fertilizers. Understanding root nodule formation may open genetic engineering avenues for optimizing nitrogen fixation performance and transferring the nodule-formation ability to other plants. A major determinant of nodule numbers and quality in soybean is microRNA 160 (miR160), which dictates developmental stage-specific auxin sensitivity by targeting repressor auxin …
