URE — Cucumis sativus

Summary

CsURE (CSA_5G590070) on cucumber chromosome 5 encodes a urease enzyme (EC 3.5.1.5) with urease activity, nickel binding, and toxin activity, comprising multiple urease subunit domains. The protein localizes to the urease complex and cytosol. This gene is associated with urea breakdown, fruit and seed development, seed germination, cell growth, regulation of growth, ethylene biosynthesis, lipid metabolism, fermentation, detoxification, and syngamy. It is linked to numerous agronomic traits including nitrogen, carbon, potassium, and nitrate content, leaf chlorophyll content, net photosynthetic rate, transpiration rate, water use efficiency, stomatal resistance, leaf area index, stem diameter, plant height, respiration rate, and germination rate. Studies of related genes in other species connect the urease family to nickel tolerance, nitrogen recycling, and traits including fruit weight, firmness, lycopene and sugar content, root and shoot biomass, and chlorophyll content.
