Figure 3.

Nucleotide variation of a 1,593-bp segment of hsr-omega among 12 alleles from the heat-resistant and susceptible lines. Dotted line under the block diagram of the 5′ end of the gene indicates the segment sequenced. Depicted are only the variable nucleotide positions (numbered) adjacent to the equivalent EMBL sequence (file DM18307). Dots and positions not included indicate bases are identical to the EMBL entry. Δ indicates a deletion variant. Allele a indicates hsr-omega^a, and b indicates hsr-omega^b, as determined by DGGE. Gray shading represents exon sequence. Figure not to scale.
