Research in Dr. Nguyen’s laboratory is focused on soybean genomics and comparative genetics of plant stress responses. Three overall research areas are: (a) soybean genome mapping and molecular breeding, (b) functional genomics of drought tolerance, and (c) nutritional genomics.

Soybean cDNA array

Soybean genome mapping and molecular breeding: Our laboratory is part of a national effort aimed at the development of a high resolution physical map of William 82 soybean genome based on restriction fingerprinting of BAC clones. We developed 6-dimensional BAC pools and contribute to the anchoring of genetic markers to the physical map. We are constructing a standard genetic map using close to 800 progenies from a cross of Forrest and Williams 82. Currently we focus on mapping QTL controlling SCN resistance and analysis of candidate genes for the SCN resistance response. Populations have been developed for mapping QTL and candidate gene analysis for isoflavone and sapponin accumulation in soybean. Our long range goal is to understand the genetic basis of QTL underlying important traits utilizing information from the integrated genetic and physical maps and to develop high throughput marker-assisted selection for soybean improvement in collaboration with the breeders.

Functional genomics of drought tolerance: Drought is a major abiotic stress limiting soybean productivity. Drought also affects soybean seed composition. A series of molecular, cellular and physiological changes occur in drought stressed plants. To understand the regulatory networks and mechanisms of drought tolerance, we use both forward and reverse genetic approaches. We currently characterize gene expression products at the transcriptome, proteome and metabolome levels. Using microarray, we are conducting gene expression profiling of soybean leaf and root under drought stress to elucidate the pattern of gene expression and signaling cascades. Laser capture micro-dissection technique is being used to target specific cell types. We validate expression results through q-RT PCR and gene function analysis. We are also conducting a comparative genomics study between soybean and model plants, Medicago truncatula and Arabidopsis under drought stress. We have sequenced and deposited more than 17,000 ESTs associated with root hair and drought responses in soybean roots. To support the transcript profile data, we are searching protein profile to gain a comprehensive understanding of the changes in protein expression levels during stress and recovery stages. In the long term we aim to combine candidate gene analysis with the QTL mapping effort.

Soybean protein profiling

Another major ongoing research program on drought is the NSF funded project: functional genomics of root growth and root signaling in maize under drought stress. As part of the umbrella of plant stress research we are elucidating gene regulatory network of soybean seed development under drought stress using transcriptome, proteome and metabolome tools. We are engineering soybean for the production of drought tolerant plants by translational genomic approach and cloning and over expression or silencing of soybean genes based on transcript and protein profiling studies.

Nutritional genomics: Another major initiative in lab is to identify novel soybean metabolites for human health and nutrition which eventually contribute to improve soybean nutritional value. In collaboration with Prof. Davis Nes at Texas Tech University, we are working to modify the sterol composition of cell membranes to affect drought and temperature tolerance in plants, to modify phytosterol composition to generate resistance to phytopathogens, and to increase the amount of phytosterols in lipid esters of seed oils to benefit human health. Phytosterols in human diet can lower serum cholesterol.
