Research Overview


The goal of my research is to improve upon the natural resistance of crop plants in order to reduce our dependency on pesticides and to improve crop yields, thereby contributing to sustainable agricultural systems and to feeding the growing population in the world. My future research will focus on the perception of microbial and herbivore-associated signals by the plant defense machinery. I will expand on my experience working with tomato, insect pests and microbes, combined with methods from molecular biology, genetics, and biochemistry in order to increase our understanding about the molecular players involved in plant defense systems.

Current Research Projects

The focus of my research in the Martin Lab is the identification of plant proteins involved in the perception of microbial pathogens of tomato. Previous work I contributed to showed that, in addition to the well-studied flg22, a second conserved region of bacterial flagellin, called flgII-28, is recognized by tomato in an FLS2-independent manner (Clarke et al., 2013). Additionally, I worked with a tomato breeding program at North Carolina State University to screen heirloom tomato varieties in order to evaluate their differential responses to treatment with different microbe-associated signals, including flgII-28 (Veluchamy et al., 2014). Using an flgII-28 insensitive cultivar identified in this screen, I isolated the flgII28 receptor, called FLS3, by bulked segregant analysis and a mapping-by-sequencing approach (Hind et al. submitted). I confirmed direct binding of flgII-28 to FLS3 using a novel photo-affinity labeling strategy developed in collaboration with the Schroeder lab and funded by the TRIAD Foundation. I also demonstrated that bacterial effector proteins could suppress FLS3 signaling. I am currently exploring sequence variants of both FLS3 and flgII-28 found in natural populations which I anticipate, when combined with structural information provided by a collaborating laboratory, will illuminate key regions essential for FLS3 binding to flgII-28. This information may assist in targeted engineering of FLS3 to broaden the potential for recognition of a diverse group of bacterial pathogens.
