Genetic characterization of Rpp1-mediated Asian soybean rust resistance using in-depth transcriptomic and genomic analyses
Asian Soybean Rust, caused by the fungus Phakopsora pachyrhizi, is one of the most destructive diseases affecting soybean yield worldwide. Rpp1 is one of the six known resistant loci that can confer qualitative resistance in soybean resulting in either red-brown lesions with no or limited …

Genetic characterization of a dominant susceptible Rpp1 allele and analysis of quantitative resistance to Asian soybean rust
Asian soybean rust (ASR), caused by fungal pathogen Phakopsora pachyrhizi, is a yield-threatening disease in soybean growing countries (Hartman et al. 2012; Godoy et al. 2016). The yield loss can reach as high as 80% if the conditions are conducive, and no control measures are taken (Yorinori et …

Characterizing soybean rust resistance in Glycine tomentella and effect of temperature and a fungicide on Phakopsora pachyrhizi uredinia production of urediniospores
Soybean rust (Phakopsora pachyrhizi H. Syd. & Syd.) causes significant economic losses in yield in many soybean-growing areas worldwide. Since most if not all commercial soybean cultivars are susceptible, research continues to search and characterize resistance. Perennial Glycine species have many …

Evaluation of resistance in Glycine max to Fusarium virguliforme and in perennial Glycine species to Phakopsora pachyrhizi and Heterodera glycines
Soybean [Glycine max (L.) Merr.] averages approximately 40% protein and 20% oil and is one of the world’s most important crops. Production of the crop is increasing, especially in less developed countries. Occurrence of diseases and pests affecting soybean have increased as production has expanded …

Characterizing soybean rust resistance within populations of Glycine tomentella and the inheritance and characterization of soybean aphid resistance in PI 587663, PI 587677, PI 587685, and PI 594592
Soybean rust, caused by Phakopsora pachyrhizi Syd., is known to cause significant damage to soybean yields in many production areas worldwide. Most soybean cultivars are susceptible to the fungus and even though sources of resistance have been discovered within the USDA soybean germplasm bank, …

Phakopsora pachyrhizi growth in tissue of leaves from resistant and susceptible soybean germplasm
Soybean rust, caused by Phakopsora pachyrhizi, is one of the most potentially devastating foliar diseases of soybean, particularly in areas with mild winters. Tan lesions with two or more sporulating uredinia indicate a susceptible reaction. Resistance to soybean rust is characterized by the …

Economic Aspects of Crop Pest Management and Monarch Conservation
… conserve Monarchs. The second chapter estimate soybean farmers' value of information provided by alternative configurations of a monitoring network for soybean rust (Phakopsora pachyrhizi). It shows that a network of 400 sentinel plots can maximize the expected profit of soybean farmers provided …

Detection of viable urediniospores, morphological characterization in resistant and susceptible genotypes, and germ tube anastomosis of Phakopsora pachyrhizi
Soybean rust, caused by Phakopsora pachyrhizi, is a major foliar disease of soybean affecting soybean yields in many soybean-growing areas throughout the world. After the reports of its first occurrence in Brazil in 2001 and the continental United States of America in 2004, research on the disease …

Evaluation of soybean cyst nematode (SCN) resistance in perennial glycine species and genome-wide association mapping and genomic prediction study for SCN resistance in common bean and prediction of the short distance movement of soybean rust urediniospores through machine learning
… management strategies for important diseases of soybean. Soybean cyst nematode (SCN; Heterodera glycines; HG) is a widely occurring and damaging pathogen with a wide host range. SCN is the leading cause of soybean yield loss in the US and it will likely become a major yield-limiting threat to …

Melanin-independent accumulation of turgor pressure in appressoria of Phakopsora pachyrhizi
… infection process. In Phakopsora pachyrhizi, the soybean rust pathogen, the appressoria are hyaline. Our objective was to ensure the absence of a melanin layer specifically between the appressorial cell wall and plasma membrane, as well as to determine the turgor pressure of P. pachyrhizi …

Evaluation of fertile lines derived from the hybridization of Glycine max and G. tomentella
… into many crops, but has not been utilized in soybean (Glycine max), besides a few examples involving its ancestor, G. soja. G. tomentella (2n=78) is a wild, perennial relative in the tertiary gene pool of cultivated soybean G. max (2n=40). G. tomentella has been shown to have high levels of …
