1. Phenotype Annotation at TAIR
Tanya Berardini

2. Current Status
Phenotypes are associated to organisms (germplasms) and linked to references
Curation is mainly done in unstructured full text
Pilot study of structured annotation completed
PaTO not yet implemented

5. papillae:abnormal
style:abnormal
septum development:incomplete
leaf:serrate

6. Same challenges as other databases
Large corpus of literature
Set number of curators with many diverse responsibilities
Different ways of paper prioritization

7. Capturing phenotypes from the literature
Single paper, describing single aspect of phenotype
Single paper, describing multiple aspects of the organism’s phenotype
Multiple papers describing different aspects of the organism’s phenotype
Multiple papers, describing the same phenotype
First mention? Who gets the attribution? Does it matter?
Use a recent review?
What is appropriate use of time? Cost-benefit analysis.

8. Storing complex annotations in the database
Right now, GO as a model for assocations:
1 association = 1 gene product + 1 CV term
How do we deal with multiple ontologies in one association?
1 association = 1 germplasm + 1 anatomy term + 1 PATO term (+ others)
