PlantCircRNA

Circular RNAs (circRNAs) represent recently discovered novel regulatory non-coding RNAs. While they are present in many eukaryotes, there has been limited research on plant circRNAs. We developed PlantCircRNA (https://plant.deepbiology.cn/PlantCircRNA/) to fill this gap. The two most important features of PlantCircRNA are (1) it incorporates circRNAs from 94 plant species based on 39,245 RNA-sequencing samples, and (2) it imports the original AtCircDB and CropCircDB databases. We manually curated all circRNAs from published articles, and imported them into the database. Furthermore, we added detailed information of tissue as well as abiotic stresses to the database. To help users understand these circRNAs, the database includes a detection score to measure their consistency and a naming system following the guidelines recently proposed for eukaryotes. Finally, we developed a comprehensive platform for users to visualize, analyze, and download data regarding specific circRNAs. This resource will serve as a home for plant circRNAs and provide the community with unprecedented insights into these mysterious molecule.环状RNA（circular RNAs, circRNAs）是近年发现的新型调控型非编码RNA。尽管这类RNA广泛分布于诸多真核生物中，但针对植物环状RNA的研究仍相对匮乏。为此，我们开发了PlantCircRNA数据库（https://plant.deepbiology.cn/PlantCircRNA/）以填补这一研究空白。该数据库的两大核心优势为：其一，基于39245个RNA测序样本，整合了94种植物的环状RNA数据；其二，收录了原始的AtCircDB与CropCircDB两大数据库资源。我们对已发表文献中的全部环状RNA进行了人工筛选、整理与注释，并将其导入该数据库。此外，我们还为数据库补充了详尽的组织表达及非生物胁迫相关信息。为帮助用户更好地理解这些环状RNA，数据库提供了用于衡量其检测一致性的评分体系，以及一套遵循近期真核生物通用命名规范的命名系统。最后，我们搭建了综合性科研服务平台，支持用户针对特定环状RNA开展可视化展示、数据分析及数据下载工作。本资源将成为植物环状RNA研究的专属知识库，为科研共同体提供针对这类神秘分子的前所未有的研究视角。
