URE — Solanum lycopersicum

Summary

SlURE (URE, SOLYC05G014970.3) on tomato chromosome 5 encodes a urease enzyme, confirmed by urease activity and multiple urease-subunit domains (Urease_alpha_N_dom, Urease_beta, Urease_gamma). The gene is associated with urea breakdown, ammonia oxidation, nitrogen fixation, and nickel binding. It is linked to systemic acquired resistance, immune response, chlorophyll fluorescence, and detoxification. Annotated associations include fruit weight, firmness, lycopene, sugar, and amino acid content, as well as shoot and root biomass, plant height, stem thickness, leaf number, and water use efficiency. The gene is also connected to nickel tolerance, manganese, phosphorus, and potassium content, and photosynthetic and transpiration rates. Studies of related genes in other species link the family to nitrogen recycling, leaf chlorophyll content, and germination rate.
