The trait descriptors developed by individual breeders are stored in the cvterm table, and linked from phenotype.attr_id.attr_id
The trait descriptors list with observed values for each species can be accessed and downloaded from the section 'Research Crops and Descriptor/Evaluation Data Queries' at www.ars-grin.gov.
Currently, Solanaceae breeders' ontology exists, and Rosaceae breeders also developed standard trait descriptors as part of RosBreed project, which are also stored in the cvterm table.
The current public apple dataset includes 125 504 phenotypic measurements divided between 95 trait descriptors of 91 varieties plus 552 genotypic data points.
This SP to PATO mapping allows SGN to give breeders direct access to trait descriptors, eliminating the need to use multiple vocabularies, as well as using very granular and Solanaceae specific trait values (e.g. SP 0000332 'spreading habit 30-15 degrees').
Trait descriptors in the page are organized into groups, such as 'Appearance' and 'Production' that have been previously specified by the data provider (breeder), so that breeders can easily navigate among traits.
Not all traits were recorded on all animals.> -wrap-foot> The dairy data used in this study were collected from the milk records kept on the farms and follow the trait descriptors commonly used by organisations such as National Milk Records Ltd (Harrogate, North Yorkshire, UK).
Whereas here, we re-define this trait as the fraction of network pixels found in the lower 2/3 of the network, where the lower 2/3 of the network is defined based on the network depth (see Table 1 for trait descriptors).
We advocate using species traits as community descriptors, to determine quantitative links between pesticide toxicity and community alterations.
A relatively weak congruence between taxonomic and trait-based community descriptors highlights their complementarity in understanding the underlying mechanisms of community changes.
