Date: Oct 19, 2015. Katie Wilkins: Population Diversity of Xanthomonas oryzae pv oryzicola TAL Effectors and their Candidate Targets

Katie Wilkins is a Computational Biology PhD Candidate in the Bogdanove lab in the Plant Pathology and Plant-Microbe Biology section of the School of Integrative Plant Science at Cornell University.

Xanthomonas oryzae pv oryzicola is the causal agent of bacterial leaf streak of rice, a disease that can lead to up to 30% yield loss in this staple crop. Disease progression is mediated in part by the secretion of transcription activator-like (TAL) effectors that upregulate host genes by binding to corresponding promoter regions. Genes upregulated by TAL effectors can confer host resistance or enhance host susceptibility. Knowledge of these important TAL effector-target pairs informs breeding of resistant rice varieties. To determine the distribution of TAL effectors and their candidate targets at the population level, we sequenced 10 strains of Xanthomonas oryzae pv oryzicola and performed RNA-Seq of rice inoculated with each strain. We also used population level conservation to evaluate potential importance of the identified TAL effectors and their candidate targets.
