Boron deficiency causes physiological disorders in crops, thereby affecting their agronomic traits and ultimately significantly reducing crop yield and quality. Compared to some monocotyledonous or cereal crops, oilseed rape has a higher demand for boron. Therefore, this paper reviews the functions and research progress of boron transport channels and transporters in oilseed rape, as well as their relationships with nitrogen nutrition, carbohydrates, and salt tolerance. However, the boron utilization efficiency and key candidate genes in oilseed rape have not yet been clearly elucidated. Further investigation of the underlying mechanisms and the development of oilseed rape varieties with improved boron-use efficiency are warranted.
