How to Contribute Data to MaizeGDB
|
|
MaizeGDB accepts data that meets these criteria:
-
Data adheres to the FAIR data principles
-
Data and metadata have been published in a publically available
scientific journal
-
Primary data is deposited in the appropriate repository (like NCBI)
-
Data is licensed as public data (See
https://creativecommons.org/licenses).
-
Comprehensive metadata (information about your dataset) is provided and
meets MaizeGDB standards for the data type
-
Additional criteria may be required depending on the data type
MaizeGDB will accept data directly from researchers. Some types of data
must also be deposited at standard repositories, as MaizeGDB is not a
permanent repository for primary data. The MaizeGDB team
can advise on the correct repository and help with the submission, if
needed. More detailed information on criteria by datatype is below.
It is particularly important that all sequence data be submitted to NCBI's
GenBank (US), EBI's
ENA (Europe), or the
DDBJ (Japan). These repositories
share all of their data on a daily basis, so data submitted toby any of
these will be visible at all three.
BECOME A COMMUNITY CURATOR
Members of the maize community are also encouraged to become community
curators. Community curators can contribute comments to most data types,
including gene loci, gene models, markers, et cetera. To create a community
annotator account, follow the link at the top of the page marked
"login/register" and check the box
labeled "I am interested in being a MaizeGDB curator" when you fill
out the form to "Create an Annotation Account". You will be contacted via
e-mail when your account is activated.
If you already have a MaizeGDB login but are not a community curator,
click here to request permission to be a curator.

NEW GENES, GENE FUNCTION, AND GENE TO GENE MODEL ASSOCIATIONS
If your research is identifying new genes, providing evidence of
gene function, and/or linking gene loci to gene models, it would be
very helpful to MaizeGDB and the maize community, as well as
increasing visibility of your research if you submit this information
directly to MaizeGDB rather than relying on the MaizeGDB curators
reading your paper and extracting this information to load into the
database. The number of maize papers published each month is much
greater than the number of papers that can be curated. Send your paper
to a MaizeGDB curator to have your gene
function information loaded into the MaizeGDB database.
Notes can be added directly to records at MaizeGDB by researchers.
To add a note, you will need a community curation account. Log in to
the site using the login/register link displayed at the top of any
MaizeGDB page. Once logged in, click "Add free text annotation" in
the annotation section of most data record displays.
GENOME ASSEMBLIES
Preparing a genome assembly for hosting at MaizeGDB is a
lengthy process. The best practice is to contact a
MaizeGDB sequence curator before submitting your
assembly to Genbank, so we can work together to insure you comply
with the MaizeGDB and long term repository requirements.
To be hosted at MaizeGDB, Genome Assemblies must:
-
Be submitted to GenBank,
EBI's ENA or
DDBJ. All three share data
daily. Submitting contigs is not sufficient- the assembly itself
must be submitted. This will involve creating BioSample, BioProject,
and WGS records. Be as complete and as accurate as possible.
-
A MaizeGDB Genome Assembly and Annotation Metadata Template must
be filled in. Request a template from a
MaizeGDB sequence curator.
-
Sibling seed and pedigree must be deposited at GRIN and GRIN
ccession specified in metadata.
-
A contact person from your team/consortium must be assigned to
coordinate with MaizeGDB staff in a timely manner.
ANNOTATIONS
Genome annotations (gene models) can be hosted at MaizeGDB in the
form of browser tracks and/or downloads of GFF or FASTA files.
It is best to have both transcript and protein FASTA. Additional
data is also accepted, for example, SNP alignments, orthologs, et
cetera. Contact a MaizeGDB sequence curator
for more information.
OTHER NUCLEOTIDE SEQUENCES, INCLUDING INDIVIDUAL GENES
Non-genome nucleotide sequences should also be submitted to
GenBank,
EBI's ENA
or the
DDBJ.
GenBank (US), EBI (Europe), and DDBJ (Japan) share sequence data on a
daily basis, so data can be submitted to any of the three.
Data sets that can be aligned to one or more reference genomes hosted
by MaizeGDB can also be added to genome browsers. the
Contact a MaizeGDB sequence curator for more
information.
PROTEIN SEQUENCES
NEXT GENERATION SEQUENCE READS
MAPPED SEQUENCE READS AND OTHER EXPRESSION DATA
MAIZE SNPS
GenBank dbSNP no longer accepts non-human SNPs. Maize SNPS should
be submitted to
EBI's
EVA. It is important to submit SNPs to EVA because EVA will provide
permanent identifiers for each SNP, and will collapse identical SNPs
into one record, maintaining the original submission identifier as
well as a consensus identifier.
MaizeGDB will also host tracks of aligned SNPs on the genome browsers.
Note that MaizeGDB does not have sufficient personnel to do the
alignments. Contact a MaizeGDB team member
for more information.
GENOTYPE AND PHENOTYPE DATA
MaizeGDB had a long history of curating genotype and phenotype data
from individual genes or small sets of genes. Detailed lab-driven
data about any gene is important to the Maize community, as this is
the best functional data we can have. We want to curate as much of
this type of data as possible. This includes detailed descriptions
of mutant phenotypes and phenotypic changes to mutant expression in
various genotypes. This type of data can be submitted by email to the
MaizeGDB curators.
MAPS
MaizeGDB team welcomes genetic maps. Please contact a
MaizeGDB curator for more information.
METABOLOMICS, IONOMICS AND OTHER DATA TYPES
Contact a MaizeGDB team member if you have a
dataset you would like hosted at MaizeGDB which is not listed here.
We will work with you to see if and how your data can be hosted. To
learn more about data repositories for these types of data, please
see the FAIR data page.

FAQs
|
|
|
WHERE DOES THE DATA STORED AT MAIZEGDB COME FROM?
-
The original data was inherited from the MaizeDB and ZmDB projects.
-
Sequence data comes from GenBank, genome assembly and annotation
groups, and other research groups that are producing genomic,
transcriptomic, and proteomic sequence data for maize.
-
Other types of bulk data are contributed by community members,
usually in standard file formats like GFF, VCF, BED and are added
to the database by members of the MaizeGDB Team.
-
Pubic data from published literature are hand curated and entered
record-by-record by MaizeGDB and community curators.
HOW DO I BECOME A COMMUNITY CURATOR?
To create a community annotator account, follow the
link at the top of the page marked
"login/register" and check the box to become labeled "I am interested
in being a MaizeGDB curator" when you fill out the form to "Create an
Annotation Account". You will be contacted via e-mail when your
account is activated.
HOW CAN COMMUNITY MEMBERS CONTRIBUTE DATA?
MaizeGDB staff members regularly attend the Plant and Animal Genome
Conference in San Diego, California and the Annual Maize Genetics
Conference. To schedule a meeting at any of these conferences,
use the feedback form at the top of this page to contact the
MaizeGDB team, or you can contact a specific
MaizeGDB member.
Contact MaizeGDB directly with a request to host your data, using the
feedback button at the top of the page or contact
a specific MaizeGDB member.
Notes can be added directly to records at MaizeGDB by researchers.
To add a note, you will need a
community curation account. Log in
to the site using the login/register link displayed at the top of
any MaizeGDB page. Once logged in, click "Add free text annotation"
in the annotation section of most data record displays.
Although researchers are encouraged to use a standard long-term
repository that is appropriate for the type of data, large datasets
can be made available through MaizeGDB by special arrangement. Use
the feedback form at the top of this page to contact the MaizeGDB
team or contact a specific MaizeGDB member to
find out what arrangements can be made to accommodate your data.
If
possible, it is best to contact the MaizeGDB Team before you begin to
generate large datasets so that a standardized format can be agreed
upon and so that a customized pipeline can be created for importing
your data in a timely and efficient manner.
WHEN CAN I EXPECT DATA I GENERATED TO APPEAR AT MAIZEGDB?
The MaizeGDB database is typically updated the first Tuesday of each
month.
Unless you have contacted us to make specific arrangements to
accommodate your data, you shouldn't expect it to appear at the
MaizeGDB site unless our data curators have curated your paper,
usually because it was recommended by the
Editorial Board. Use the feedback form
at the top of this page to contact the MaizeGDB team to find out what
arrangements can be made to make your important data become available
through MaizeGDB.
THE AGENCIES THAT FUND OUR RESEARCH HAVE ENCOURAGED ME TO CONTRIBUTE DATA TO
MAIZEGDB. WHAT CAN I DO TO ENSURE THAT MAIZEGDB WILL TAKE MY DATA?
If you wish to contribute a large dataset, you should contact the
MaizeGDB team to make special arrangements for
its inclusion at MaizeGDB.
Note that contacting MaizeGDB personnel well in advance and committing funds
from your grants to cover the cost of personnel to curate your data into
MaizeGDB are the best ways of ensuring that MaizeGDB can accommodate
your requests for data storage.
In general, if the data you are generating have historically been stored at
MaizeGDB (e.g., your project is planning to generate genetic maps using a
new set of probes), it is very easy for us to commit to including your
data in the database. However, if you are proposing to create data of a
type that is not currently stored at MaizeGDB, more work would be
required of the staff at MaizeGDB (e.g., it may be necessary to make
new tables in which to store your data and new data displays would be
needed for the website).
Unless you have contacted the MaizeGDB team, please do not assume that we can
accommodate your data. We are happy to make special arrangements to create new
tables and data displays (e.g., we collaborate with the FSU
Cytogenetic Map of Maize Project to
make their cytological images and data available).
In summary, we encourage you to contact us prior to reporting to the funding
agencies that we will take any and all maize data your project plans to
generate.
