Phylogenetic trees of two nucleolar Pumilio protein families in the representative species of green plants (a and b) and the protein structures of nucleolar APUMs and ChPUMs (c). a and b Phylogenetic relationship among the putative nucleolar Pumilio proteins belonging to the APUM23 and ChPUM2 family (a) and the APUM24 and ChPUM3 family (b). The phylogenetic trees were constructed using the maximum likelihood LG + G model using MEGA7 software [29] with 1000 bootstrapping replicates. Two independent nucleolar Pumilio proteins of red algae (Chondrus crispus and Galdieria sulphuraria), Drosophila melanogaster, Homo sapiens, and Saccharomyces cerevisiae were used as outgroups. c Primary protein structures of APUM23 and APUM24 from Arabidopsis thaliana and ChPUM2 and ChPUM3 from Chara corallina. Black hexagons indicate Puf RNA-binding domains
