摘　要：摘　要：随着非编码RNA 预测方法的推陈出新及高通量测序技术的发展，先前由于研究技术所限未能被鉴定注释的较长非编码RNA 逐渐成为研究热点。目前人们在拟南芥、水稻、玉米、苜蓿等高等模式植物中发现大量中等长度及长链非编码RNA，其中一些非编码RNA 在植物生长发育及环境信号响应等关键生物学过程中发挥着重要的调控功能。将着重介绍长度大于50 个核苷酸的非编码RNA 在多种高等植物中的序列、分子特征与功能鉴定的方法与最新进展。同时，对长链非编码RNA 在高等植物中最新报道的作用模式与分子机理进行归纳总结，并展开讨论。

Abstract: Abstract: With the development and innovation of noncoding RNA prediction algorithms and high-throughput sequencing technologies， the research on previously uncharacterized longer noncoding RNAs gradually becomes a frontier in the field. At present， large amounts of intermediate-sized and long noncoding RNAs have been identified in model plants including Arabidopsis， rice， maize， and Medicago etc. And those emerging genes accomplish variety of biological function during development and in response to environmental stimuli. Here， we reviewed the current and fast growing knowledge on the systematic identification and annotation of noncoding RNAs with the size of longer than 50 nt in higher plants. In addition， the recent advances on the regulatory mechanisms of plant long noncoding RNAs will be summarized and discussed.
