PtRNAdb search module is designed for user to search this database using different combination of search terms or a single query also. Available search options include : Genome, Plant category or Plant Name, Amino acid, Anticodons and Infernal Score Range. By default, the "Nuclear" category in the "Search by Genome" option is selected and "Infernal score" is set to maximum. If the user does not select any option then all the data of tRNAs from Nuclear genome present in PtRNAdb will be the output. With some combinations, the output page might take some time to display results, depending on the size of the output. Kindly read the NOTES carefully.
