Codon bias and ENC-GC3s plots of seven grass TLP gene families. A Box plot of ENC values for seven grass tubby-like protein (TLP) gene families. ENC indicates the number of valid codons. The value of ENC ranges from 20 to 61. An ENC value less than 35 indicates strong codon bias. B ENC-GC3s plots of seven grass TLP gene families. The ENC-GC3s plot was used to evaluate the influence of mutation selection on codon bias. GC3s indicates the GC content at the third codon site. The horizontal axis represents the GC3s value, and the vertical axis represents the ENC value
