Plant Pathology, Stress Biology, and Crop Improvement

Developing innovative solutions for crop resiliency and improvement

Worldwide, emerging and endemic pathogens, pests, 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 relevant to Texas and U.S. agriculture. We are using the latest genomics and genetics tools to understand plant stress responses to diverse plant biotic and abiotic stress conditions, as well as improve crop cultivars’ stress resilience using genome editing, biotechnology, and breeding strategies.

Crop improvement through biotechnology and CRISPR-based genome editing.

Utilizing cutting-edge technologies for crop trait improvement Research funded by U.S. Department of Agriculture-National Institute of Food and Agriculture Hatch Act; Foundation for Food and Agricultural Research, Texas A&M AgriLife Research Project Description The goal is to utilize novel bioengineering and CRISPR-based genome editing technologies for crop improvement. To enable this, we have established plant…

Genomics and Genetics of plant stresses 

Understanding genes and regulatory networks in plant stress responses and disease Diseases and abiotic stresses of vegetables, fruits, and commodity crops result in annual yield losses of US $300 million or more. Towards enhancing the stress resilience of crops,  we are pursuing genetic and genomics-based characterization of diverse environmental and biotic stresses in citrus, potato, tomato,…

Fastidious plant diseases and plant-microbe interactions

Seeking solutions against pathogens that cannot be cultured for laboratory study Fastidious (unculturable) plant pathogens devastate 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 CandidatusLiberibacter solanacearum, causes annual crop losses of…
