This is something on which we have been working on
for some time, first for the development of NetPlantGene
and NetGene2 together with Søren Brunak, and more
recently for the validation of gene prediction software.
We have a paper in press on this issue (to appear in
BioInformatics very soon I guess). Linked to this paper
we developped a dataset of Arabidopsis genes in their
genomic context (Araset) containing 168 validated genes.
Many of these genes were not properly annotated ...
which is not (alas) a big surprise: it's just very easy
unfortunately to fulfil your first asking ! In our data
set there are some "big" genes, i.e. with many exons,
although even bigger ones are documented.
Araset is available on our web site :
please refer to our paper when using this dataset !
