PMEI — Brassica oleracea

Summary

BoPMEI (BOLC102_C08P060430.1_BOLC102_V1) on cabbage chromosome 8 encodes a pectinesterase inhibitor, belonging to the PCW enzyme inhibitor and invertase/methylesterase inhibitor domain families. The gene is associated with pectinesterase inhibitor activity and enzyme inhibitor activity, and has been linked to the downregulation of enzyme activity, pollen tube growth, and pollen development. It is also associated with pectin methylesterase inhibition and fungal resistance. Studies of related genes in other species link the PMEI family to root morphology traits, root length, and proline content.
