PDC1 — Cucumis melo

Summary

MELO3C007227.2, designated PDC1, encodes a pyruvate decarboxylase enzyme (EC 4.1.1.1) that requires thiamine pyrophosphate and magnesium for activity. This cytosolic protein is associated with anaerobic respiration, fermentation, and the response to lowered oxygen levels, as well as aerobic respiration and aldehyde anabolism. PDC1 has been connected to fruit development and stress responses. Associations with agronomic traits include leaf area index, respiration rate (measured as CO2 output), root length, and plant height. Related genes in other species link the family to similar metabolic processes, though this is not established for melon.
