Chapter synopsis: This chapter describes recent insights provided by genomic and microscopy analyses of three bacterial pathogens of sugar cane, ‘Xanthomonas vasicola pv. vasculorum’, X. albilineans and Leifsonia xyli subsp. xyli, the causal agents of gumming, leaf scald and ratoon stunting, respectively. The chapter addresses genomic-based hypotheses regarding adaptation of the three pathogens to sugar cane and the origin of their respective ancestors. It examines the strategies used by X. albilineans and L. xyli subsp. xyli to spread in sugar cane. The chapter looks ahead to the development of further functional studies to improve the understanding of the interactions between sugar cane and bacterial pathogens, which are likely to contribute to better control of bacterial diseases of sugar cane
