Function of Plant U-box Protein in Plant Innate Immunity and Its Research Progress

To analyze the function and mechanism of plant U-box protein in plant innate immunity, the U-box structure characteristic and the difference between U-box and RING-finger domain were introduced in this review. Moreover, the classification of U-box protein and classification characteristics were summarized. In addition, the functions and mechanism of U-box protein, such as SPL11, PUB12/PUB13 and PUB17, in regulating plant PTI signaling transduction were reviewed in this paper. Similarly, the functions and mechanism of U-box protein, such as ACRE276, PUB17, CMPG1 and MAC3A/MAC3B, in regulating plant ETI signaling transduction were also reviewed. Based on this review, the structure characteristics and biochemical functions of plant U-box protein, functions and mechanism of U-box protein in plant innate immunity were clarified. In addition, the research on plant U-box protein provides gene resources and reference information for plant resistance molecular breeding.
