G + C content for tRNA coding and promoter regions. G + C content was analyzed either in the region coding for the tRNA itself (empty circles) or in a promoter region of the same length for each of the genomes in our dataset (filled circles). Coding regions show a clear increase with temperature (R = 0.91 p = 4.9 × 10−30), while promoters region do not (R = −0.3 p = 7 × 10−3).
