植物至少需要14种必需的宏量和微量营养素。其中，阳离子钾（K+）、阳离子钙（ca2 +）和阳离子镁（Mg 2+）是植物生长发育所需的大量元素，在植物生长发育过程中发挥着重要作用。在过去的几十年里，在确定和描述负责这些矿物质的吸收和分布的分子成分方面取得了很大的进展，因此为操纵和优化这些过程提供了选择。本章详细概述了K+、ca2 +和Mg2+在植物中的功能，它们是如何被吸收和分布的，以及特定系统的遗传操作如何有助于提高作物产量。
Plants require at least 14 essential macroand micronutrients. Of the macronutrients, the cationic potassium (K+), calcium (Ca 2+), and magnesium (Mg 2+) are required in large quantities and play distinct roles in plant growth and development. In the past decades, great progress has been made in identifying and characterizing the molecular components that are responsible for the uptake and distribution of these minerals and as such provides options to manipulate and optimize these processes. This chapter gives a detailed overview of the functions of K+, Ca 2+, and Mg2+ in plants, how they are taken up and distributed, and how genetic manipulation of specific systems may contribute to improved crop production.
