Schematic trees of NPY proteins and AGC kinases. (A) A tree of NPY proteins that belong to a family with 32 members in Arabidopsis. The founding member of this superfamily is NPH3. For simplicity, the details of the NPH3 clade and the other large clade are not shown. (B) A tree of the AGC kinase family. More detailed phylogenetic trees of the 2 families have been published (18, 21, 24). The GenBank accession numbers for NPY genes are At4g31820 (NPY1), At2g14820 (NPY2), At5g67440 (NPY3), At2g23050 (NPY4), and At4g37590 (NPY5). The GenBank accession numbers for PID and its homologs are At2g34650 (PID), At2g26700 (PID2), At1g53700 (WAG1), and At3g14370 (WAG2).
