硼胁迫下植物生理调控机制的研究进展

The Advances of Physiological Regulatory Mechanism of Plants under Boron Stress

硼是植物的必需营养元素,它对植物的许多生理过程有着重要的作用,特别是在低硼或高硼胁迫情况时会影响植物正常的生理代谢。本文将对最近几年有关硼胁迫下植物生理调节机制的研究成果进行综述,着重阐述低硼胁迫下诱发植物产生硼高效吸收、转运、分配和再利用的机理,以及在高硼胁迫下植物自身可能存在的调控机制。

Boron is an essential nutrient element for plant.It plays an important role in variety of biological processes of plants and may affect the normal physiological metabolism especially in the low B or high boron stress situations.This review is related on recent research about the regulatory mechanisms of plant in boron stress,focusing on the mechanism of B-efficient absorption,transport,distribution and reuse in low B stress and the possible regulatory mechanisms in high B stress in plant.
