Cecilia Tamborindeguy

TITLE: Assistant Professor

EDUCATION:

  • Post-Doctoral Associate, Department of Plant Pathology and Plant-Microbe Biology, Cornell University, 2006-2008
  • Ph.D., Plant Biosciences, INP-ENSAT, France 2004
  • M.S., Plant Biosciences, INP-ENSAT, France 2000
  • Agronomic engineer, INP-ENSAT, France 2000
RESEARCH INTERESTS:

Insects are vectors of plant virus and other pathogens. My research program focuses on understanding the mechanisms underlying plant pathogen transmission by insects. I am particularly interested in identifying aphid proteins responsible for luteovirus transmission using genomic approaches. Currently, I am working in collaboration with Fred Gildow (Penn State University) and Stewart Gray (Cornell University) with a population of Schizaphis graminum differing in their ability to transmit Cereal yellow dwarf virus strain RPV (CYDV-RPV). Increasing our knowledge of the mechanisms of virus transmission will facilitate the control of viral diseases in fruits and crops.

I am also interested in studying transmission of Candidatus liberibacter by psyllids. Psyllids are vector of two of the most important emerging agricultural diseases in the US, Huanglongbing (HLB), also referred to as Asian Citrus Greening and Zebra Chip of Potato. Presently we are undertaking a research project in collaboration with Herman Scholtof and Eric Mirkov (TAMU) to analyze interactions between the psyllid Bactericera cockerelli and the agent causing Zebra Chip Disease.

I am also involved in the annotation of the genome of Acyrthosiphon pisum, the model aphid. I have participated on the annotation of transcytosis, immunity and defense, and ion channel genes.
