PLMItRNA, a database for tRNAs and tRNA genes in plant mitochondria: enlargement and updating

The current version of PLMItRNA has been realized to constitute a database for tRNA molecules and genes identified in the mitochondria of all green pl ants (Viridiplantae), It is the enlargement of a previous database original ly restricted to seed plants [Ceci,L.R., Volpicella, M., Liuni,S., Volpetti , V., Licciulli, F. and Gallerani, R. (1999) Nucleic Acids Res., 27, 156-15 7]. PLMItRNP, reports information and multialignments on 254 genes and 16 t RNA molecules detected in 25 higher plants (one bryophyta and 24 vascular p lants) and seven green algae. PLMItRNA is accessible via the WWW at http:// bio-WWW.ba.cnr.it:8000/srs6/.
