The gene structure, conserved motifs and domains in pPLA genes between Arabidopsis and four cotton species. (A) The ML phylogenetic tree was constructed based on the full-length sequences of Arabidopsis, Maize and four cotton species pPLA proteins using MEGA 7.0 software. Different subfamilies are highlighted in different colors. (B) Conserved motif of Arabidopsis, Maize and four cotton species. Different colored squares represent different motifs, named motif1-motif15. (C) The conserved domains in Arabidopsis, maize and four cotton species pPLA proteins. (D) The exon-intron structure of Arabidopsis, maize, and four cotton species pPLA genes. Blue for exons; black lines for introns
