From: Widespread occurrence of ‘Candidatus Phytoplasma ulmi’ in elm species in Germany
Alignment of 16S–23S spacer regions (5′ – 3′) of ‘Ca. P. ulmi’ and closely related phytoplasma strains. Nucleotide differences of the other sequences to the ‘Ca. P. ulmi’ sequence are indicated by lowercase letters. The positions of the forward primer, the TaqMan probe and the reverse primer are underlined and given from left to right, respectively. -, indicates gaps in the alignment. ≈, indicates bases not depicted. Numbers above the alignment correspond to nucleotide positions relative to the ‘Ca. P. ulmi’ sequence deposited under acc. no. AF122911
