Ultrastructural aspects of AY group phytoplasmas in sieve tube elements of diseased plants have been studied by several researchers using transmission and scanning electron microscope observations (Hirumi and Maramorosch, 1973; Haggis and Sinha, 1978; Marcone et al., 1995; Marcone and Ragozzino, 1996; Fránová and Šimková, 2009; Fránová et al., 2009). A draft genome sequence is presented for a strain of “Candidatus Phytoplasma asteris” affecting canola plants in Saskatoon, Canada. The distribution in this summary table is based on all the information available. These leafhopper species are polyphagous and can transmit the pathogens to a wide range of host plants (Lee et al., 1998b, 2004; Weintraub and Beanland, 2006).
