Fig S3. Comparison of tetranucleotide frequencies and GC content between MCR / MTR operons and surrounding gene context in the scaffolds.
The
principal component analysis was conducted based on the sliding window GC
content and 4mer profile. Red and Blue circles indicate fragments within
the MCR and MTR operons, respectively. To avoid statistical bias caused by
small sample size, scaffolds with length less than 5kb were excluded from this
analysis.
