ODC — Solanum lycopersicum

Summary

SOLYC04G082030.1, designated SlDCOR (also known as ODC or DCOR) on tomato chromosome 4, encodes a protein with ornithine decarboxylase and lysine decarboxylase activities, belonging to the Orn/DAP/Arg decarboxylase family and containing a PLP-binding barrel domain. The gene is associated with putrescine metabolism, arginine metabolism, the urea cycle, polyamine metabolism, proline metabolism, nicotine anabolism, phytochelatin anabolism, the ascorbate-glutathione cycle, and other biological processes. It has been linked to fruit volume and shape, chlorophyll and flavonoid content, root number and length, respiration rate, drought tolerance, and salt tolerance. The encoded protein localizes to the cytoplasm and exhibits homodimerization and identical protein binding activities. Studies of related genes in other species connect the family to amino acid content and salt response.
