From: The PIN-FORMED (PIN) protein family of auxin transporters
Simplified cladogram of the Plantae supergroup illustrates the distribution of PIN sequences within the group. Species with complete, fully assembled genomes containing PIN sequences are shown as green arrows, and those lacking it as yellow arrows, above their respective lineages. Phylogenetic relationships were revised according to literature (Glaucophyta - red-green algae [57], Mesostigmatales/Chlorokybales [58], Streptophyte algae [20], bryophytes [59, 60], and vascular plants (Embryophyta) [61]). The dotted lines indicate branching events where the consensus about branching order is not well established yet. Arrows indicate the following species. Angiosperms: Arabidopsis thaliana; Oryza sativa; Populus trichocarpa; Vitis vinifera. Lycopodiopsida (club mosses): Selaginella moellendorffii. Bryophyta (mosses): Physcomitrella patens. Chlorophyta (green algae): Chlamydomonas reinhardtii; Ostreococcus tauri; Micromonas pusilla. Rhodophyta (red algae): Cyanidioschyzon merolae.
