摘　　要：草酸通常被认为是新陈代谢最终的惰性产物。近期的研究表明:在植物体内草酸(盐)可以被进一步分解,其分解产物又参与了特定的生长发育过程及抗生物胁迫反应,因此植物体内草酸(盐)的代谢又引起了人们的广泛关注。本文就植物体内草酸(盐)的生物合成、存在形态及其被分解过程中的生理生化作用作一简要概述。Oxalic acid has been usually regarded as an inert end product of the metabolism. Recently studies indicated that oxalate could be fitrther degradated by oxalate oxidase, and their intermediate components could be not only involved in plant specific developmental processes but also in plant defensive responses to biotic and abiotic stress. Accordingly, it would be growing concerns about the oxalate metabolism in plant. In this paper, we briefly reviewed some aspects of oxalate about biosynthesis, existing form, degeneration and physiological and biochemical functions.
