GC content shift is an evolutionary genome-wide change in the GC content of an organism. The evolutionary consequences of such a change is unknown. They are detected by comparing the genomes of two related organisms that share a recent common ancestor, and determining if their have different:
- AT/GC genomic composition
- High rate of synonymous mutations for syntenic gene pairs
- Amino acid usage frequencies
- Codon usage frequencies

GEvo analysis of syntenic regions from the Schizosaccharomyces fungi japonicus strain yFS275 (top) and pombe 972h- (bottom). Gene models are colored based on the percent GC content of GC3. Red is AT rich; green GC rich; yellow 50/50 AT/GC. Results may be regenerated at: http://genomevolution.org/r/pi7
