Nitrogen is the largest mineral nutrient required by plants, and it is the main factor restricting plant growth and development. At present, plants have evolved different strategies to response changes of nitrogen in the soil, in order to ensure adequate nutrition and nitrogen supply. DUR3 family urea molecules are important intermediate products in the process of nitrogen metabolism in organisms. In plants, DUR3 family proteins co-transport urea and protons with high affinity. It plays a vital role in the nitrogen metabolism of plants. In addition, DUR3 family proteins can not only transport urea but also participate in the transport of polyamines in fungi. This review introduces the current research progress of DUR3 family genes. focusing on the Arabidopsis urea transporter AtDUR3 and yeast urea transporter ScDUR3. It is hope to provide a theoretical basis for studying the role of the urea transporter DUR3 family in the process of nitrogen metabolism, and provide a reference direction for the next research of the urea transporter DUR3 family.
