piRNAclusterDB

piRNA cluster database provides comprehensive data on piRNA clusters in multiple species, tissues and developmental stages based on small RNA sequence data deposited at NCBI's Sequence Read Archive (SRA). The new version provides a major update for the piRNA cluster database, expands it from 12 to a total of 51 species with hundreds of new datasets, and revises its overall structure to enable easy navigation through this large amount of data.piRNA簇数据库（piRNA cluster database）依托美国国家生物技术信息中心（National Center for Biotechnology Information, NCBI）序列读取存档（Sequence Read Archive, SRA）中收录的小RNA测序数据，为多个物种、组织及发育阶段的piRNA簇提供全面的相关数据。该数据库的新版本完成了重大更新：物种覆盖范围从12种拓展至总计51种，新增数百套数据集，并对整体架构进行优化，以实现对海量数据的便捷浏览。
