Cloning and expression analysis of four heat shock protein genes in Ericerus pela (Homoptera: Coccidae).

ABSTRACT: To explore the function of small heat shock protein genes (shsps) and hsp70 in Ericerus pela, we cloned the full-length cDNA sequences of hsp21.5, hsp21.7, hsp70, and hsc70 and the genomic sequence of hsc70. Open reading frames of the four hsps were 570, 564, 1,908, and 1,962 base pairs (bp), respectively, which encode proteins with calculated molecular mass of 21.5, 21.7, 69.8, and 71.6 kDa. Amino acid sequence analysis revealed the presence of the conserved Hsp motifs in all four proteins. The genomic DNA of hsc70 had four introns. ep-hsp21.5 was orthologous and ep-hsp21.7 was species specific. Expression of all four transcripts during heat or cold stress and development was examined by quantitative real-time polymerase chain reaction. All four hsps were upregulated during heat or cold s
