From: Diversity of plant defense elicitor peptides within the Rosaceae
Identity comparison of plant elicitor peptides (Pep) amino acid sequences in 100 Rosaceae varieties. Heat map showing pairwise comparison of all 214 Pep sequences. Colors indicate increasing identity (%) from high (red), through white, to low (blue). The position of Pep1, Pep2, Pep3 and Pep4 sequences is indicated (top and left). Bootstrapped neighbor-joining tree of Pep amino acid sequences, constructed using the CLC tool (left). A higher-resolution image of the tree is displayed in Additional file 5
