PCN — Solanum tuberosum

Summary

StPCN (PGSC0003DMG401010623) on potato chromosome 4 encodes a protein containing WD40 repeat domains, placing it in the WD40/YVTN repeat-like domain superfamily. This gene is associated with the regulation of auxin polar transport, meristem maintenance and growth, root meristem growth, lateral root formation, leaf development and leaf vascular tissue pattern formation, as well as embryo development ending in seed dormancy and post-embryonic plant organ development. 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 family to meristem identity and plant embryo development traits.
