PlantRNA

The PlantRNA database compiles tRNA gene sequences retrieved from fully annotated plant nuclear, plastidial and mitochondrial genomes. For each tRNA gene, the linear secondary structure is given as well as biological information. This includes 5'- and 3'- flanking sequences, A and B box sequences, region of transcription initiation and poly(T) transcription termination stretches, tRNA intron sequences, aminoacyl-tRNA synthetases and enzymes responsible for tRNA maturation and modification. Data on mitochondrial import of nuclear-encoded tRNAs as well as the bibliome for the respective tRNAs and tRNA binding proteins are also included.PlantRNA数据库（PlantRNA database）汇编了从已完成全注释的植物细胞核、质体及线粒体基因组中获取的转运RNA（transfer RNA, tRNA）基因序列。针对每一条tRNA基因，数据库均提供其线性二级结构与相关生物学信息，涵盖5'端与3'端侧翼序列、A盒与B盒序列、转录起始区域、poly(T)转录终止区段、tRNA内含子序列、氨酰-tRNA合成酶（aminoacyl-tRNA synthetases）以及负责tRNA成熟与修饰的各类酶类。此外，数据库还收录了细胞核编码tRNA的线粒体导入相关数据，以及对应tRNA与tRNA结合蛋白（tRNA binding proteins）的相关文献资料。
