植物生长发育需要大量和稳定的常量营养元素，包括氮(N)、磷(P)、钾(K)、钙(Ca)、镁(Mg)和硫(S)。在整个生命周期中，来自外部环境的大量营养素供应不足或过多都会引发植物在表型和分子水平上的一系列反应。在植物对大量营养元素胁迫反应的相互交织的分子网络中，非编码RNAs(NcRNAs)，主要是microRNAs(MiRNAs)和Long ncRNAs(LncRNAs)可能是营养供应和植物需求之间协调的关键调节因子，而响应ncRNA的靶模块和相互作用机制因元素和物种而异。为了对营养响应的ncRNA及其下游分子进行全面的鉴定和功能表征，高通量测序已经产生了大量的组学数据，作为第一步进行比较表达谱分析。在这篇综述中，我们重点介绍了ncRNA介导的调控响应大量营养素胁迫的最新发现，特别是大规模测序工作，以筛选植物中候选的营养响应ncRNAs，并讨论了理论研究的潜在改进，以更好地指导作物育种实践。
Macronutrient elements including nitrogen (N), phosphorus (P), potassium (K), calcium (Ca), magnesium (Mg), and sulfur (S) are required in relatively large and steady amounts for plant growth and development. Deficient or excessive supply of macronutrients from external environments may trigger a series of plant responses at phenotypic and molecular levels during the entire life cycle. Among the intertwined molecular networks underlying plant responses to macronutrient stress, noncoding RNAs (ncRNAs), mainly microRNAs (miRNAs) and long ncRNAs (lncRNAs), may serve as pivotal regulators for the coordination between nutrient supply and plant demand, while the responsive ncRNA-target module and the interactive mechanism vary among elements and species. Towards a comprehensive identification and functional characterization of nutrient-responsive ncRNAs and their downstream molecules, high-throughput sequencing has produced massive omics data for comparative expression profiling as a first step. In this review, we highlight the recent findings of ncRNA-mediated regulation in response to macronutrient stress, with special emphasis on the large-scale sequencing efforts for screening out candidate nutrient-responsive ncRNAs in plants, and discuss potential improvements in theoretical study to provide better guidance for crop breeding practices.
