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 (i) it incorporates circRNAs from 94 plant species based on 39 245 RNA-sequencing samples and (ii) 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.

PlantCircRNA：植物环状 RNA 的综合数据库


环状 RNA （circRNAs） 代表最近发现的新型调节性非编码 RNA。虽然它们存在于许多真核生物中，但对植物 circRNA 的研究有限。我们开发了 PlantCircRNA （https://plant.deepbiology.cn/PlantCircRNA/） 来填补这一空白。PlantCircRNA 的两个最重要的特点是 （i） 它基于 39 245 个 RNA 测序样本整合了来自 94 种植物物种的 circRNA，以及 （ii） 它导入了原始的 AtCircDB 和 CropCircDB 数据库。我们手动整理了已发表文章中的所有 circRNA，并将它们导入数据库。此外，我们还向数据库添加了组织和非生物胁迫的详细信息。为了帮助用户了解这些 circRNA，该数据库包括一个用于衡量其一致性的检测分数和一个遵循最近提出的真核生物指南的命名系统。最后，我们开发了一个综合平台，供用户可视化、分析和下载有关特定 circRNA 的数据。该资源将作为植物 circRNA 的家园，并为社区提供对这些神秘分子的前所未有的见解。
