Phylogenetic analysis (A), schematic visualization of protein (B), and gene structure (C) of EXPANSINS in C. annuum. A. Phylogenetic tree performed using the neighbor joining method in MEGA 7.0 with 1000 bootstraps with p-distance model. B. Protein structure showing the signal peptide (pink), double-psi beta-barrel (DPBB; burgundy) and pollen allergen (grey) domains. Scale, 250 amino acids. C. Gene structure with exons in green, introns as a solid line and 5′ and 3′ UTR in blue. Break in second intron of CaEXPA15 is 500 bp
