Boron (B) is an essential micronutrient for the growth, development, and maintenance of cellular integrity in vascular plants, and is especially important in cell wall synthesis and reproductive development. Rapeseed ( L.), one of the dominant oil crops globally, has a high boron demand and its yield is dramatically decreased under B-deficiency conditions. Rapeseed, which is very sensitive to boron deficiency, suffers from reduced growth and reproductive development, ultimately causing severe yield losses. Here, we reviewed the present state of knowledge on the physiological function of boron in rapeseed, mechanisms of boron uptake and transport, specific effects of boron deficiency in rapeseed, and approaches to alleviate boron deficiency in rapeseed at the agronomical and molecular levels. A specific focus is given to recent molecular breakthroughs and agronomic approaches that may improve boron efficiency. The review focuses on practices that may alleviate the problems caused by boron-deficient soils by investigating the genetic and physiological mechanisms of boron tolerance. In summary, this review describes the integration of molecular information with practical agronomy as an important aspect of breeding future nutrient-efficient rapeseed cultivars that can sustain increasing yields while being cultivated in regions with boron-deficient soils.
硼（B）是维管植物生长、发育和维持细胞完整性所必需的微量营养素，在细胞壁合成和生殖发育中尤为重要。油菜（ Brassica napus L.）是全球主要的油料作物之一，对硼的需求量很高，在缺硼条件下其产量会大幅下降。对硼缺乏非常敏感的油菜，生长和生殖发育会受到影响，最终导致严重的产量损失。在此，我们综述了关于硼在油菜中的生理功能、硼吸收和运输机制、油菜缺硼的具体影响以及在农艺和分子水平上缓解油菜缺硼的方法等方面的现有知识。特别关注了可能提高硼效率的近期分子突破和农艺方法。该综述通过研究硼耐受性的遗传和生理机制，重点关注可能缓解缺硼土壤所引起问题的实践方法。总之，本综述将分子信息与实际农艺相结合，描述为培育未来能在缺硼土壤地区种植且持续增产的营养高效型油菜品种的一个重要方面。
