Homologous Gene Identification from Genomic and Transcriptomic Data.

(A) General workflow of the identification of homologs of MIR390, AGO7, TAS3, and ARF2, ARF3, or ARF4 (ARF2/3/4). Main criteria used in gene identification are listed in yellow boxes, and downstream bioinformatics and statistical analyses conducted for each gene family are itemized in light-brown boxes.

(B) Proportion of MIR390 and TAS3 genes in different lineages of land plants, organized as seven groups of species. For TAS3, two genes found in the only lycophyte (P. drummondii) were grouped in the monilophytes for simplicity.
