Alignment of partial Hsp90 genomic sequence from variant M. arenaria population from traveler's tree compared with sequence from morphologically typical M. arenaria from MD and composite cDNA sequence assembled from M. arenaria EST. The genomic sequence was trimmed of degenerate primer end bases, and the 3’ end of the EST composite extending beyond the genomic amplicons was trimmed. Genomic intron sequences from the M. arenaria population are in lower case. Abbreviations: R = A or G; Y = C or T; W = A or T; M = A or C; S = C or G; dash (-) indicates missing data; colon (:) indicates intron gaps not present in EST. Positions that vary in at least one of the sequences are indicated by overline.
