Genomic consequences of transitions from cross- to self-fertilization on the efficacy of selection in three independently derived selfing plants

Table 2 Mean values of expression, gene length, frequency of optimal codon usage ( F _op ) and base composition, measured as GC-content at synonymous sites (GC3s) for genes sampled from four genotypes of Eichhornia

For each of the genotypes, the genes were divided into two categories based on expression level including the top (‘high’) and bottom (‘low’) and 10^th percentile of expression. The values for all loci are summarized in the category, ‘total’.
