Research Emphasis

Plant Stress Biology and Biotechnology

World-wide, pathogens, insects and abiotic stresses cause major losses to agricultural production and productivity. Our lab employs integrated approaches for basic and translational studies of crop stress responses in model and crops. We are using the latest genomics, genetics, and bioinformatics tools to study plant stress responses to diverse plant biotic and abiotic stress conditions, as well as enhance their stress tolerance using biotechnology and breeding tools.

Current Projects

Fastidious plant diseases of vegetables and fruits

 

Fastidious (unculturable) plant pathogens are devastating to several food and commodity crops. For instance, citrus greening or Huanglongbing disease, caused by a fastidious bacterium, Candidatus Liberibacter asiaticus, is inflicting approximately $3 billion in annual losses. Similarly, potato zebra chip disease, caused by Candidatus Liberibacter solanacearum, causes annual crop losses of US $25 million in Texas alone. We are utilizing the latest genomic, genetic and biotechnology tools to discover and utilize novel disease resistance genes to confer tolerance to the devastating pathogens. Furthermore, to overcome the challenges in studying fastidious pathogens, we are developing new technologies and bioassays that enable culturing and propagation of these pathogens. These tools are being used to conduct high throughput screening of antimicrobial genes and therapeutics.

 

Bioenergy grass diseases and crop improvement

 

Diseases and abiotic stresses of grasses result in annual yield losses of US $300 million or more. However, very little is known about the gene regulatory networks that function in grass defenses, particularly related to grass viral diseases. To enable fundamental studies of cereal and bioenergy grass defense pathways, we are pursuing genetic and genomic studies using model grasses, Brachypodium distachyon (a C3 grass) and Setaria viridis (a C4 grass). The research findings are further translated to agronomic grasses such as sugarcane and energycane using biotechnology and breeding tools.
