PCN — Solanum tuberosum

Summary

StPCN (PGSC0003DMG400011543) on potato chromosome 12 encodes a protein containing WD40 repeat domains, placing it in the WD40/YVTN repeat-like superfamily. This gene is associated with multiple developmental and physiological processes, including root meristem growth, meristem maintenance, lateral root formation, leaf development, leaf vascular tissue pattern formation, post-embryonic plant organ development, embryo development ending in seed dormancy, and regulation of auxin polar transport. It is also linked to chlorophyll fluorescence, photosynthetic rate, and quantum yield. The encoded protein localises to the nucleus. Related genes in other species link the WD40 repeat family to meristem organization and embryo development.
