RNA-Seq（RNA测序）允许精确定量测定全球基因表达模式，因此彻底改变了玉米的转录组分析。近年来，遗传分析已经确定了许多控制玉米根系结构和根毛伸长的基因。此外，RNA-Seq已被应用于解剖单个根的结构和功能。在本章中，我们总结了玉米根发育在整个根、组织和单个细胞水平上的转录组学解剖的现状。此外，我们强调了目前的知识，玉米根的转录组响应干旱胁迫和养分供应。最后，我们概述了新的发现有关的基因表达可塑性在初级根的玉米杂交种在杂种优势的早期表现。
RNA-Seq (RNA-Sequencing) allows for precise quantitative determination of global gene expression patterns and has therefore revolutionized transcriptome analyses in maize. In recent years, genetic analyses have identified numerous genes that control maize root system architecture and root hair elongation. In addition, RNA-Seq has been applied to dissect structure and function of individual roots. In this chapter, we summarize the current state of the transcriptomic dissection of maize root development on the level of whole roots, tissues, and individual cells. Moreover, we highlight the current knowledge of transcriptome responses of maize roots to drought stress and nutrient availability. Finally, we outline novel findings related to gene expression plasticity in primary roots of maize hybrids during the early manifestation of heterosis.
