A Citrus Canker Problem Space

Introduction

Citrus canker is of current scientific and research interest because of its deleterious effects on the citrus industry. The pathogen, Xanthomonas axonopodis pv citri, originated in Asia and has been eradicated from Florida twice in the 20th century. However, in 1995 the current epidemic began in dooryard trees in Miami and West Palm and in the intervening time has wiped out more than 25% of Florida’s citrus production capacity.

This problem is multidisciplinary and can engage students in investigating host-pathogen relationships, host and pathogen genetics and phylogenies, epidemiology of canker, disease control methods, regulations related to the epidemic, influence of weather factors on the spread of this disease, and economic impact of citrus canker on world wide citrus production.
