Expedited access to some of CottonDB's most Frequently Asked Queries.
We'd like to have all the CottonDB FAQs available right here.

** You can help! **
If you have a CottonDB question you want to ask, please let me know. Somebody else probably has the same question.

Germplasm

  • Gossypium Species Summaries: a table matrix of species names and genome, haploid chromosome number, geographic origin, and number of accessions held, number of sequences, and number of DNA libraries currently available in CottonDB.
    --- Suggested by: Sarah Palmer ---

  • Germplasm Trait Evaluation Information [View trait descriptions]
    • Production Traits (set 1): Boll weight, lint index, and lint percent
    • Production Traits (set 2): Boll weight, Seed index, and Productiveness
    • Seed Quality Traits: Embryo index, embryo oil percent, and embryo percent
    • Other Traits (get evaluation results by selecting a sepecific trait below or selecting * for results of all traits).
                   Trait (* for all)
                 

Markers and Maps

  • Map Data Summaries lists species, genome; mapping population parents, type, and size; number of loci; references and contact person for each map currently available in CottonDB.
  • Mapped Sequences, with information of mapping position.
    --- Suggested by: Cairui Lu ---
  • Nearby Loci: A list of all Loci that are within a specified distance of a specified Locus on any map.
  • Map Positions, by marker type: Select a marker type to see a list of loci and mapping positions.

Primers and Probes

  • SSR primers and mapping information.: Select a microsatellite set and the type of information you would like to view.
      Microsatellite Set (* for all)           
                 Primer source information: primer sequences, repeat motifs, source sequence names, source germplasm.
                 Primer mapping information: maps and positions, etc. where they have been mapped.
  • SSR Polymorphisms: A list of primer names, allele sizes, germplasm names, germplasm cottondb_id, and species names.

References

  • Find references within a certain time period. (Keyword can be left blank).
              From year   to year ,   Keyword
  • Search by author, keyword and/or date. (Author and Keyword can be left blank. "since" must be a number.)
              Author ,    Keyword ,    since

Sequences and DNA Libraries

  • DNA Library summaries: a list of libraries including information on source species, source germplasm, source tissue, contact person, and the number of sequences derived from the library and currently available in CottonDB.

Variety Test Reports

Nomenclatures

  • Chromosome Names of tetraploid cotton: A table of proposed and formerly assigned At- and Dt-genome chromosomes, with mapped sequence information.
  • Reference Names in CottonDB are assigned using an "A-B-C" system, where A = journal code; B = journal volume number; C = starting page number of the article. Reference Name Table lists Journal codes, journal names, the number of articles that currently in CottonDB, and other information about the journal.
  • Universal Names are chosen based on primer or probe names and used to make connections among Locus, Primer, Probe, Sequence, Clone, etc. Universal Name Table lists universal names with names that are used in different data classes.
  • Germplasm Top Names are chosen from the multi-names and identifiers associated with each germplasm record. Currently only data records that are within data sets of NPGS Cotton Plant Variety Protection (USA), NPGS Crop Science Registration (USA), Pedigrees of Upland and Pima Cultivars, plus a few germplasm records from public reports have top names. Inputs from germplsm experts are needed to establish appropriate top names for records that currently use cottondb_id as their top name. However, query can be made on any identifier in the germplasm record. Top Name Table lists germplasm top names with all other names and identifiers that have been used in data records.
