Evidence for putative heat stress-activated Ty1-copia-like retrotransposons. (a) qPCR expression analysis of selected genes under heat stress. SmTCL, S. microadriaticum Ty-copia-like; Fox-1, RNA-binding protein fox-1 homolog; CYPLIIA8, Cytochrome P450. Error bars show the standard error of the means. **one-tailed t-test P < 0.01; ***P < 0.001. (b) Domain arrangements of various LTR retroelements. LTR, long terminal repeats; PBS, primer binding site; gag, group-specific antigen; pol, pol polyprotein; PR, protease; INT, integrase; RT, reverse transcriptase; RH, ribonuclease H; PPT, polypurine tract; env, envelope protein. (c) Maximum likelihood phylogeny of 32 reverse transcriptase or RNA-dependent RNA polymerase amino-acid domains of various retrotransposons and viruses. Dotted lines indicate polyphyletic groupings and the scale bar indicates number of substitutions per site. Node support values indicate bootstrap support.
