根对于吸收水分和养分以及在土壤中的固定至关重要。它们具有高度可塑性,能够在发育和生理上适应不断变化的环境条件。了解这种生长和发育背后的分子机制需要根转录组学,蛋白质组学和代谢组学的知识。基因组学方法,包括最近出版的根表达图谱,根蛋白质组,和环境特异性根表达的研究,揭示了复杂的转录和转录后网络的根的发展。挑战在于进一步利用这些数据集中的信息来了解根系生长和发育的基本原理。在这篇综述中,我们重点介绍了研究人员朝着这一目标所取得的进展。
Roots are vital for the uptake of water and nutrients, and for anchorage in the soil. They are highly plastic, able to adapt developmentally and physiologically to changing environmental conditions. Understanding the molecular mechanisms behind this growth and development requires knowledge of root transcriptomics, proteomics and metabolomics. Genomics approaches, including the recent publication of a root expression map, root proteome, and environment-specific root expression studies, are uncovering complex transcriptional and post-transcriptional networks underlying root development. The challenge is in further capitalizing on the information in these datasets to understand the fundamental principles of root growth and development. In this review, we highlight progress researchers have made toward this goal.
