PER3 — Solanum lycopersicum

Summary

SlPER3 (SOLYC07G047740.3) on tomato chromosome 7 encodes a secretory haem peroxidase with lactoperoxidase and transglycosidase activities, and is associated with heme binding and transmembrane receptor protein serine/threonine kinase activity. The gene is linked to cell wall organization or biogenesis, tissue remodeling, and responses to phenylpropanoids, as well as endMT, chitin anabolism, and arginine metabolism. Associations include pericarp and stigma color, fruit dry weight and volume, leaf moisture and nitrogen content, seedling height, stem thickness, root morphology, and osmotic adjustment capacity. SlPER3 is also associated with dehydration, cold, and salt tolerance, reactive oxygen species production, potassium deficiency response, and leaf cell death. Related genes in other species link the family to vascular development and leaf venation.
