K is the most abundant cation in the grape berry. Here we focus on the most recent information in the long distance transport and partitioning of K within the grapevine and postulate on the potential role of K in berry sugar accumulation, berry water relations, cellular growth, disease resistance, abiotic stress tolerance and mitigating senescence. By integrating information from several different plant systems we have been able to generate new hypotheses on the integral functions of this predominant cation and to improve our understanding of how these functions contribute to grape berry growth and ripening. Valuable contributions to the study of K in membrane stabilization, turgor maintenance and phloem transport have allowed us to propose a mechanistic model for the role of this cation in grape berry development.
钾是葡萄浆果中含量最丰富的阳离子。在此，我们聚焦于葡萄植株体内钾的长距离运输和分配方面的最新信息，并推测钾在浆果糖分积累、浆果水分关系、细胞生长、抗病性、非生物胁迫耐受性以及延缓衰老中的潜在作用。通过整合来自几种不同植物系统的信息，我们得以就这种主要阳离子的整体功能提出新的假设，并增进了我们对这些功能如何促进葡萄浆果生长和成熟的理解。在钾在膜稳定、膨压维持和韧皮部运输方面的研究中所做出的宝贵贡献，使我们能够提出一个关于这种阳离子在葡萄浆果发育中作用的机制模型。
