给定元素的积累是一个复杂的过程,由对吸收、结合、运输和隔离至关重要的基因产物网络控制。许多这些基因和生理过程影响不止一种元素。因此,为了了解元素是如何调节的,有必要测量细胞、组织或生物体(离子组)中尽可能多的元素。共享其网络组成部分的元素根据所研究植物的物种和基因型以及它们生长的环境而有所不同。最近的几篇论文描述了离子组如何响应环境或探索控制离子组的遗传学的高通量元素分析研究。当与新的基因分型技术相结合时,离子组学提供了一种快速方法来识别控制植物元素积累的基因。
The accumulation of a given element is a complex process controlled by a network of gene products critical for uptake, binding, transportation, and sequestration. Many of these genes and physiological processes affect more than one element. Therefore, to understand how elements are regulated, it is necessary to measure as many of the elements contained in a cell, tissue or organism (the ionome) as possible. The elements which share components of their network vary depending on the species and genotype of the plants that are studied and environment they are grown in. Several recent papers describe high-throughput elemental profiling studies of how the ionome responds to the environment or explore the genetics that control the ionome. When combined with new genotyping technologies, ionomics provides a rapid way to identify genes that control elemental accumulation in plants.
