Select from following two ways.
In general, we recommend to use DDBJ Nucleotide Sequence Submission System
In cases of, large number of sequences, many features, and/or long sequences, MSS is more useful.
See Organism qualifier.
For detail, see either of following cases;
2. In case of unidentified species names, proposing a new species etc.
3. environmental sample
In cases of sequences derived by direct molecular isolation from soil, sea water, etc. i.e. a bulk environmental DNA sample by PCR with or without subsequent cloning of the product, DGGE, or other anonymous methods, see What is ENV ? – environmental samples.
For description of organism qualifier, see 3. Environmental samples.
Though frequently confused, the term, 'environmental samples', does NOT mean "wild type". If sequences are derived from isolated or cultured organisms, the sequence data are not classified into environmental samples.
Yes you can. It ought to be required at 'instructions to authors' of most of journals to submit sequence data to DDBJ (, EMBL-Bank or GanBank) before the paper submission.
During submission of sequence data, select status for your REFERENCE as follows.
Regardless you are to publish academic paper or not, DDBJ accepts your submission of sequence data.
If you have no plan to paper publication, you have to fill following items of REFERENCE.
When you change your plan after sequence data submission, i.e. if you publish a paper, see When our paper was published, what should I do? on Data Updates/Corrections and contact us from this form to send request with subject "Our paper was published".
DDBJ accepts updating requests only from the original submitter of the entry.
Basically, we strongly recommend to describe joint submitters more than two persons, e.g. at least a true worker and an adviser, to avoid lost communication in future.
For instance, when the length of sequence is 199035 bp and a CDS feature is located in the range from 199001 to 100, you should describe the location of CDS feature as
See also Description of Location in detail.
As feature annotation, we strongly recommend you to describe CDS (protein-coding sequence)，rRNA，tRNA and so on.
Please inform us in detail, when you apply to Mass Submission System.
When it is difficult for you to annotate your genome sequence, we recommend to use some public services, for example, MiGAP.
The amino acid sequence for CDS feature will be automatically translated from nucleotide sequence according to location and other items, and reflected into /translation qualifier. So, in general, do not enter it.
Nucleotide Sequence Submission System is an interactive application to enter all of items required for your submission on step by step basis.
To use Mass Submission System (MSS), submitters have to make submission files by themselves. So, DDBJ will review and consult for submitters on the process of making files.
Some submitters use Nucleotide Sequence Submission System to submit a lot of sequences, while some submitter use MSS to submit a few sequences.
Based on above information, select either of them as needed.
There is no limit of the number of entries to use Mass Submission System.
You can use it not only for many sequences but also for one long sequence with many features (i.e. complete genome with annotation).
