Research Summary
Genetic analysis and genome-wide association mapping
We use genotyping by sequencing and other genome complexity reduction tools to generate high density SNP markers and use these for genome wide association study (GWAS) to locate candidate SNPs for quantitative trait loci in various horticulturally important crops, fly panels for nutraceutical traits and mine site adaptation traits.

The exploitation of synthetic polyploids for producing seedless fruits is well known in watermelon. Tetraploid progenitors of triploid watermelon plants, compared with their diploid counterparts, exhibit wide phenotypic differences. In this study, we used tissues of leaf, stem, and fruit of diploid and tetraploid sweet watermelon to understand changes in gene expression and the occurrence of AS. We finally confirmed that 22 genes underwent AS events across tissues, indicating possibilities of generating different protein isoforms with altered functions of important transcription factors and transporters. Future proteome sequencing would help further resolving the variation in protein load between diploid and tetraploid.

Genomic approaches to reclaim Appalachian coal mines and coal-mine water quality analysis in West Virginia

Efficient postmining reclamation requires successful revegetation. By using RNA sequencing, we evaluated the growth response of two invasive plants, goutweed (Aegopodium podagraria L.) and mugwort (Artemisia vulgaris), grown in two Appalachian acid-mine soils (MS-I and -II, pH ∼ 4.6). Although deficient in macronutrients, both soils contained high levels of plant-available Al, Fe and Mn. Both plant types showed toxicity tolerance, but metal accumulation differed by plant and site. With MS-I, Al accumulation was greater for mugwort than goutweed (385 ± 47 vs 2151 ± 251 μg g-1). An in situ approach revealed deregulation of multiple factors such as transporters, transcription factors, and metal chelators for metal uptake or exclusion. The two plant systems showed common gene expression patterns for different pathways. Both plant systems appeared to have few common heavy-metal pathway regulators addressing mineral toxicity/deficiency in both mine sites, which implies adaptability of invasive plants for efficient growth at mine sites with toxic waste. Functional genomics can be used to screen for plant adaptability, especially for reclamation and phytoremediation of contaminated soils and waters. Currently we are working on quality of coal-mine leaching water from Appalachian Mountains.

Drosophila would be appropriate model system to evaluate plant products. We are currently working with fly association panel by feeding different nutraceutical compounds to observe the longevity as well as analyze metabolisms with regards to different human diseases and disorders.
