Qtl gramene tutorial
- 1. Welcome to the Quantitative Trait Loci (QTL) Tutorial This tutorial will describe how to navigate the section of Gramene that provides information on Quantitative Trait Loci (QTL). QTL are a statistical creation that identifies a particular region of the genome as containing a gene (or genes) that is associated with the trait being assayed or measured. Gramene v. 20

Notes de l'éditeur
- Search either by entering a term or browsing by trait category.
- Option 2: Search You can search the QTL database for a term, using the symbol "*" for wild card searches (e.g., "seed*"). The default behavior is to search all fields in the database for the supplied term, though you may choose to restrict the search to any one of the following: Trait name , Trait symbol, Trait category, Linkage group (chromosome), Published QTL symbol, QTL accession ID . Additionally, you may restrict the search to a single species by selecting it from the "Species" menu.
- Option 1: Browse by Traits The user can browse the QTL by trait categories and the trait names. Click on the name of a trait category from the list under section "Search by Trait Category." This opens a list of traits belonging to this category and tells you how many traits are in this category. This list displays a maximum of 25 trait names per page. In order to view the next 25 trait names, please click on "Next" or type the page number you want to view and hit the button "Page." The number associated with each trait tells you the number of QTL that are detected for this trait and are listed in the QTL database. You can sort the trait names in alphabetical order or by number of associated QTL by clicking on the column headers "Trait name" or "Number of QTL." Clicking on the hyperlinked trait name will perform a database search for all the QTL associated with that trait. Clicking on the hyperlinked TO accession number brings you to the appropriate entry in the Trait Ontology database where you can find the trait definition as well as its synonyms. For more information on the Trait Ontology and its use, please visit the Ontology Tutorial and Help pages.
- Ontology is where you can find the trait definition as well as its synonyms. For more information on the Trait Ontology and its use, please visit the Ontology Tutorial and Help pages.
- Goes to CMap database
- For example, if the user wants to get all QTL associated with traits, "Seed dormancy" and "Seed Longevity", on chromosome 1 from the "Rice" and "Wild Rice" species, he could do it as follows: Select "Seed dormancy" and "Seed Longevity" in the "Include" field of "Trait Names". Select "Rice" and "Wild Rice" in the "Include" field of "Species". Type "1*" in the "Include" field of "Linkage Groups". With the wild card "*", the user could include the linkage groups with the names of "1a", "1b", etc. Type "10*", "11*" and "12*" in the "Exclude" field of "Linkage Groups". In this way, the user can exclude them while using "1*".
