The structure of PgHDZ gene transcripts. The gene transcripts were clustered with MEGA in which the four subfamilies of the gene family are shown, with the transcripts in black font from subfamily I, the transcripts in pink font from subfamily II, the transcripts in blue font from subfamily III, and the transcripts in yellow font from subfamily IV. The conserved domains of the transcripts identified by NCBI Conserve Domain Search, including Homeobox, HALZ, START, MEKHLA, and the HD-Zip protein N-terminus, are shown in the left column and the conserved motifs of the transcripts identified by MEME, including motifs 1 through 10, are shown in the right column. For details of the 10 conserved motifs, see Fig. S1
