A database for tRNAs of photosynthetic eukaryotes
The PlantRNA 2.0 database compiles tRNA gene sequences retrieved from fully annotated nuclear, plastidial and mitochondrial genomes of photosynthetic organisms.
After a first version released in 2012, version 2.0 was implemented end of 2021.
This database is hosted and maintained by the IBMP (Institut de biologie moléculaire des plantes) from Strasbourg, France (
http://www.ibmp.cnrs.fr/).
The PlantRNA database provides, in addition to
tRNA gene sequences with their (linear) secondary structure,
other important biological information on:
- 5'- and 3'- flanking sequences
- tRNA intron sequences
- tRNA isoacceptors
- sites of transcription initiation and poly(T) stretches thought to act as transcription terminators
- sequences of A and B boxes involved in TFIIIC (Transcription factor for Polymerase III) binding
- aminoacyl-tRNA synthetases and enzymes responsible for tRNA maturation (RNase P, RNase Z, tRNA-nucleotidyl transferase
- and other tRNA modification enzymes)
- tRNA import into mitochondria
- references to published articles
