Evolution and roles of cytokinin genes in angiosperms 1: Do ancient IPTs play housekeeping while non-ancient IPTs play regulatory roles?

摘要

Phylogenetic tree of genes from major lineages of bacteria, archaea, and eukaryotes constructed in PhyML. Support values (Shimodaira–Hasegawalike test) >0.5 are indicated at the nodes. Color coding: green lines, ; orange lines, Class I ; pink lines, Class II ; gray lines, ; orange and pink backgrounds, putative Class I and II homologs, respectively
