Whole genome duplication and dispersed duplication characterize the evolution of the plant PINOID gene family across plant species

•‘Hypothetical Kinases’ originated the earliest in the evolutionary process of AGCVIII kinase family, and then these kinases differentiated their functions and D6PK started to appear in moss, PINOID and PINOID2 started to appear in angiosperms pioneer plant Amborella trichopoda.•Pinoid gene family experienced complex evolutionary history accompanied by many gene gain and gene loss events during plant evolution.•Whole genome duplications and dispersed duplications play important role in the evolution of Pinoid gene family.
