Fig. 1From: Control of leaf development in the water fern Ceratopteris richardii by the auxin efflux transporter CrPINMa in the CRISPR/Cas9 analysisA phylogenetic tree of representative PINs. Numbers along branches were bootstrap values (hidden if < 50%). Gene names/accessions and species names were shown at every terminal branch. Branches were colored to indicate different land plants, e.g., bryophytes in gold, lycophytes in green, ferns in blue, gymnosperms in light green, and angiosperms in purple. The investigated CrPINMa was highlighted by the name in redBack to article page
