a PCR products of Tachypodoiulus niger revealing a fragment of about 760 bp derived from genomic DNA (gDNA) and a prominent product of about 610 bp for transcripts derived from previously heat shocked animals (cDNA-hs). A faint band was also obtained from transcripts of animals that had not been subjected to heat shock (cDNA). M = 100 bp DNA-ladder. The prokaryotic hsp70 homologue DnaK ⁺ (plasmid pUHE21-2Δ12fd) was used as a positive control (DnaK); b predicted intron/exon structure of the nucleotide-binding domain of the partial hsc70 and hsp70 genes in the diplopod T. niger
