Community Annotation
Annotation of genes within the Arabidopsis thaliana genome is
a dynamic challenge in which the depth of the current EST and cDNA collections and
the state of the genomic sequence assembly dictate the quality of each predicted gene
model. At AtGDB, acknowledgement and correction of gene models (some of which may have
been improperly annotated in the current genome assembly) is made possible through the
use of User Contributed Annotations.

UCA-At2g42245:
The User Contributed Annotation (green gene structure) to the left shows how a user of AtGDB
has provided an updated annotation. This annotation explains the inconsistancy of the current
gene models with the spliced alignment of ESTs and cDNAs in this region.

Genome Annotation EVALuation
A key design feature of the AtGDB UCA system is that potentially erroneous gene structure
models in the current annotation are flagged, and cDNA and EST evidence is provided on-line
in conjunction with analysis tools. Using these automated flags, in many cases,will allow users to quickly
and confidently provide corrected gene models.
