The editor provides automatic layout of complex regulatory graphs and enables users easily to maintain, edit, and exchange publication-quality images of regulatory networks.
Instead, I would contend that the present-day distribution results from neutral fixation coupled with differences in the selection pressure to maintain edit sites (eg, there are so few 3rd position edit sites because they are silent at the protein level so there is no selection to maintain them).
Moreover, by adding users' individualized semantic information into their IOL, we provide the users with individualized services and successfully maintain users' editing intensions.
This collective attention throughout the organisation to producing, maintaining and editing the EPR – quite apart from the equipment and technical support that is required to keep the EPR operational – constitutes the EPR as significant and central to practice life.
Effectively attract and maintain an editing population.
Identified key-informants were contacted by phone, and interviewed at their work premises by one or both researchers, with notes maintained and edited within 24 h following debriefing between the authors and corroboration of findings.
Some researchers have suggested a hypothesis of genetic drift resulting in both the appearance of editing activity and fixation of mutations at editable sites [ 24- 26], with a possibility of natural selection maintaining RNA editing activity [ 24].
We confirmed empirically that A3G maintains DNA editing and virus inhibition activities in the presence of these mutations.
Therefore, these data and observations from previous studies unambiguously support a role of natural selection in maintaining RNA editing activity in plant organelles [ 24].
In agreement with [ 24], we think that the data are overwhelming in supporting a role of natural selection in maintaining RNA editing activity in organelles of plants, despite a poor understanding of its biochemical nature until now.
