硼(B)是植物生长发育必需的微量元素，缺硼会影响许多生化和生理过程。甘蓝型油菜对B的需求量大，对B缺乏极为敏感。甘蓝型油菜的种子产量和油质往往受到土壤中硼的低有效性的限制。因此，需要培育高效的甘蓝型油菜新品种，这就需要对油菜对B缺乏的反应有更深入的了解。不同品种甘蓝型油菜对低土壤B的响应存在显著的基因型差异。B高效基因型在低B条件下可以正常生长和产量，并且通常比B低效基因型具有更大的根系。甘蓝型油菜对B的吸收、运输和利用是B效率的主要机制。此外，细胞壁组分在甘蓝型油菜对B缺乏的耐受性中起着重要作用，B高效系细胞壁上的B结合位点比B低效系少。遗传和蛋白质组学分析揭示了一个复杂网络的调节，以响应B缺乏。本文综述了甘蓝型油菜对维生素B缺乏的生理和遗传反应，并讨论了维生素B缺乏的可能机制。
Abstract Boron (B) is an essential microelement for the growth and development of plants, and B deficiency affects many biochemical and physiological processes. Brassica napus L. has a high demand for B and is extremely sensitive to B deficiency. Seed yields and oil quality of B. napus are often limited by the low availability of B in soils. Developing new cultivars of B. napus with high B efficiency is therefore required, which requires a greater understanding of responses to B deficiency. Significant genotypic differences in response to low soil B have been observed among varieties of B. napus. B-efficient genotypes can grow and yield normally and usually have a larger root system than B-inefficient genotypes at low B conditions. The mechanisms for B efficiency in B. napus are attributed to B absorption, transportation and utilization. In addition, the cell wall component plays an important role in the tolerance of B. napus to B deficiency, and the B-efficient line presents fewer B-binding sites in the cell walls compared with the B-inefficient line. Genetic and proteomic analyses in B. napus revealed the modulation of a complex network in response to B deficiency. This review gives a comparative overview of the physiological and genetic responses to B deficiency in B. napus and discusses the possible underlying mechanisms of B efficiency.
