Model Organism Database (MOD) for Arabidopsis- focus on genes and their function

Heavy international usage

How does TAIR use phenotype ontologies now?

Expression pattern annotationPlant Ontology

How would we like to use anatomy ontologies?

standardized mutant phenotype descriptions!

Arabidopsis phenotype: decreased seed size

Arabidopsis gene: controls seed size

What are the barriers?

curation efficiency funding for curationlack of interoperability

reading research articles and converting data into annotations is time consuming and expensive!

Current statusPhenotype data in TAIR is still free text

2238 sequenced genes with free text phenotypes

Additional 1755 unsequenced mutant loci with phenotypes

4696 images

(total of 3993 loci)

What are the barriers?curation efficiency / funding (also applies to GO)- let’s try getting data directly from authors/ fundinglack of interoperability

Full Text FrameWe crossed syp122-1 to the EMS-induced, null alleles of PEN1, pen1-1, and pen1-4 (Collins et al., 2003). For both allelic combinations, the double mutants (identified as described in Materials and Methods) grew on soil as severely dwarfed plants with necrotic rosettes (Figure 3, A-E). When plated on MS medium, double mutant seedlings grew well for the first 2 to 3 wk. Thereafter, necrotic lesions were seen on the rosette leaves, even though these were propagated in sterile tissue culture (Figure 3A). The lesions were more frequent under high light than under low light (compare Figure3C with 3D), suggesting an enhanced susceptibility to oxidative stress. In spite of their lesions, the double mutants yielded a small amount of seed and could be propagated as true breeding lines. Processes requiring polarized secretion such as root hair tip growth, trichome morphogenesis (Figure 3A), and transmission through the pollen did not appear to be perturbed in the pen1
