Table 1.

Increasing GC content of fungal genomes increases the number of PAM sequences with higher GC content. The number of PAMs (PAM sequences ordered in decreasing GC content from left to right) found per mega base pair in the genomes (coding and non-coding regions) of fungi in Neocallimastigomycota, as well as Saccharomyces cerevisiae, Trichoderma reesei and Rhodotorula graminis. The fungi are ordered in increasing GC content. The color scale shows the abundance of PAM sequences found in the genome of each fungus, with darker cells corresponding to more PAM sequences identified.
