Genomic and genetic resource for soybean disease resistance improvement
… one of the 27 wild perennial relatives of soybean, possesses genetic diversity and agronomically favorable traits that are lacking in soybean. The first chapter describes 939-Mb draft genome assembly of G. latifolia (PI 559298) using exclusively linked-reads sequenced from a single Chromium …

Soybean disease research on green stem disorder, effects of seed treatments on Sclerotinia stem rot, and resistance to Cercospora leaf blight
Soybean plants often exhibit varying delayed maturity symptoms at the end of the growing season. One delayed maturity malady known as green stem disorder (GSD) is the occurrence of non-senescent, fleshy green stems at harvest maturity with normal, fully mature pods and seeds. Data on GSD incidence …

Identification of phytotoxins produced by fusarium virguliforme associated with foliar symptoms of sudden death syndrome and genome-wide association studies for soybean disease resistance
… from the big data, with specific interests on soybean pathology. In my first project, I applied the RNA-Seq technology to identify additional phytotoxins produced by the fungus Fusarium virguliforme, which causes soybean sudden death syndrome (SDS). A robust and comprehensive …

Rust and Purple Seed Stain of Soybeans
Rust of soybean (Glycine max), caused by Phakopsora pachyrhizi, is the most serious soybean disease in southeast Asia and Australia and is a potential threat in other soybean growing areas. Yield reductions from 30 to 50% are common. Twelve synonyms of P. pachyrhizi were reported on 87 hosts.

Conjunctive Conceptual Clustering: A Methodology and Experimentation (Learning)
… the method is used to rediscover categories of soybean disease when given a collection of 47 descriptions of diseased soybeans having one of four diseases. In a second problem, the method is used to find categories underlying a collection of blocks-world structures. In a third problem, …

Molecular response of soybean (Glycine max (L.) Merr) to Phialophora gregata
The soybean disease Brown Stem Rot is caused by infection by the fungus Phialophora gregata. Several cultivars of soybean (Glycine max (L.) Merr.) show levels of resistance to attack by the fungus. In order to determine the mechanism of this resistance, the response of whole plants and soybean …

Evaluation of Rhizoctonia solani - Heterodera glycines interactions on soybean
Rhizoctonia solani and the soybean cyst nematode (Heterodera glycines; SCN) are two soilborne pathogens that co-infest fields in soybean-producing states, contributing to significant yield reduction. Both pathogens infect the soybean radicle early in the growing season causing pre- and …

Molecular Mapping of Disease-Related Expressed Sequence Tags and Resistance Gene Analogues in Soybean
Soybean has become one of the most important crops to the United States, resulting in a need to improve its disease resistance. The objectives of this study were to 1) design primers and develop PCR-based markers from disease-related expressed sequence tags (ESTs) and resistance gene analogues …

Mapping of brown stem rot resistance, genetic yield gains, and yield impact of soybean cyst nematode
… from Five Brown Stem Rot Resistance Sources in Soybean Brown stem rot (BSR) of soybean [Glycine max (L.) Merr.] caused by Cadophora gregata (Allington & D.W. Chamb.) T.C. Harr. & McNew, can be controlled effectively with genetic host resistance. Three BSR resistance genes Rbs1, Rbs2, and Rbs3 …
