Summary of expression of MADS-box (black), MYB (blue), and TCP (red) genes involved in the differentiation of callus, stelidia and mentum (all indicated in yellow) of P. equestris and P. pulcherrimaa Expression of SEP clade 1 genes is high (indicated on the left side of the white triangle) in the large callus of P. equestris (left side) but absent (indicated on the right side of the white triangle) in the small callus of P. pulcherrima (right side). Expression of AP3 clade 1, AP3 clade 2, AGL6 clade 1, AGL6 clade 3, SEP clade 2, SEP clade 3, SEP clade 4, and DIV clade 2 genes is high (indicated on the right side of the black triangle) in the small callus of P. pulcherrima (right side) but absent (indicated on the left side of the black triangle) in the large callus of P. equestris (left side). Expression of AP3 clade 4, PI clade 1, AGL6 clade 2, and PCF clade 1 genes is high (indicated by the grey box) in the callus of both Phalaenopsis species. b Expression of SEP clade 1 and DIV clade 2 genes is high (indicated on the left side of the white triangle) in the short stelidia and absent mentum of P. equestris (left side) but absent (indicated on the right side of the white triangle) in the long stelidia and pronounced mentum of P. pulcherrima (right side). Expression of AP3 clade 1, and AGL6 clade 1 genes is high (indicated on the right side of the black triangle) in the long stelidia and pronounced mentum of P. pulcherrima (right side) but absent (indicated on the left side of the black triangle) in the short stelidia and absent mentum of P. equestris (left side). Expression of AP3 clade 2, AP3 clade 4, PI clade 1, AGL6 clade 2, AGL6 clade 3, SEP clade 2, SEP clade 3, SEP clade 4, and PCF clade 1 genes is high (indicated by the grey box) in the stelidia and mentum of both Phalaenopsis species.
