From: Origination and selection of ABCDE and AGL6 subfamily MADS-box genes in gymnosperms and angiosperms
Phylogeny of the ABCDE and AGL6 genes from 27 plant species and 361 classified coding sequences obtained using BEAST. The genes are colored as follows: AP1, blue; AP3/PI, green; AG/SHP/STK, red; SEP, yellow; and AGL6/AGL13, purple. The red values represent the probable origin and divergence time (million years ago, MYA) as calculated using BEAST of the AP1, AP3/PI, AG/SHP/STK, SEP, and AGL6/AGL13 genes in the tree. AP3/PI originated 339 MYA; AG/SHP/STK originated 322 MYA; and AP1, SEP, and AGL6/AGL13 originated 296 MYA. The divergence of SEP and AGL6/13 occurred 269 MYA, and the divergence of AP1 occurred 233 MYA
