User Guide
Enter keyword(s) and/or category/ies. Selecting categories for a query makes a search more specific. For example, you can retrieve sentences that contain the word HSN and a
Oryza sativa
gene name by typing the keyword 'SPW1' and choosing the category 'gene (Oryza sativa)'. A category hit occurs when a particular word or phrase in the sentence is defined as a member of a particular category. Categories will be concatenated by a Boolean 'and' operation to other categories and keyword(s) if present. To search for terms in categories, click on the Categories/Ontology link above.
Keywords
Separate multiple,

keywords by a comma with no white spaces (Boolean 'or').
Enter phrases in double quotes, and put a '-' sign in front of words which are to be excluded.

Narrow your search results with filter:
Put a '+' sign in front of words which have to be included, a '-' sign in front of words which have to be excluded. Enter the field of the word,
viz
author, title, year, journal, abstract, type or sentence in square brackets. Enter phrases in double quotes.
For example, to find all the papers in the search result that have
Jack
as author, but not
John
, enter +Jack-John[author]. To exclude all papers that have the phrase
double mutant
in title, enter -"double mutant"[title]. You can combine several filters and enter something like +Jack-John[author] -"double mutant"[title] +1994[year] -review[type].

Title:
Comparative analysis of RNA editing sites in higher plant chloroplasts .

Abstract:
Transcripts of land plant chloroplast genomes undergo C-to-U RNA editing . Systematic search disclosed 31 editing sites in tobacco , 27 in maize , and 21 in rice . Based on these identified sites , potential editing sites have been predicted in the transcripts from four angiosperm chloroplast genomes which have been completely sequenced . Most RNA editing events occur in internal codons , which result in amino-acid substitutions . The initiation codon AUG was found to be created from ACG by RNA editing in the transcripts from rpl2 , psbL , and
ndhD
genes . Comparison of editing patterns raises a possibility that many editing sites were acquired in the evolution of angiosperms .

Title:
The role of RNA editing in conservation of start codons in chloroplast genomes .

Abstract:
Open reading frames ( ORFs ) , encoded by the plastid genomes of tobacco , liverwort , rice and maize were aligned with a view to studying the conservation of translational start and stop codons created by RNA editing of homologous genes . It became evident that most of the homologous ORFs have conserved translation start and stop signals at the gene level . However , some of the ORFs show differences with respect to extensions of their 3 and 5 terminal regions . For example , the proposed N-termini of the
ndhD
-encoded peptides from different plant species are very variable in length and amino-acid composition . Sequence analysis of
ndhD
and the corresponding cDNA shows that editing of an ACG triplet in tobacco , spinach and snapdragon leads to the creation of an AUG codon , corresponding to the start codon in other species . Conservation of translational start codons of plastome-encoded genes can , therefore , be achieved by editing of transcripts , and the definition of plastome-encoded ORFs must take potential editing events into consideration .
