LAC7 — Solanum lycopersicum

Summary

SlLAC7 (SOLYC07G049460.3) on tomato chromosome 7 encodes a laccase, a copper-containing oxidase with p-diphenol:oxygen oxidoreductase activity, copper binding and redox functions, belonging to the Cu-oxidase family with multiple cupredoxin domains. This gene is associated with lignin breakdown, melanin and glucan anabolism, toxin anabolism, hexose metabolism, and hormone metabolism, and its product localises to the apoplast and extracellular space. SlLAC7 has been linked to several agronomic traits including fruit weight, plant height, root fresh weight, shoot dry weight, cellulose and lignin content, manganese and proline content, net photosynthetic rate, quantum yield, photochemical quenching, stomatal resistance, and drought tolerance. It is also connected to pollen development and root hair development. Studies of related genes in other species link the family to flowering time regulation.
