As described in the association file format page, one of gene,  
transcript, protein, protein structure, complex, germplasm, QTL etc  
are accepted in POC at this moment.  Regarding to "alleles", we  
haven't figured out a best way to store and display this information,  
do you have any maize alleles annotated to PO?

Right now, we are not planning to bring any sequence information to  
PO browser. This field is a default in AmiGO browser (Shuly can  
confirm this), GOC displays peptide information in this field.

What Shuly did is she retrieved TAIR's gene_associations file from  
GO's website and compared all the gene products to TAIR's gene  
association files (anatomy and temporal) to PO, and extracted all the  
genes that exist in both, associations to GO and to PO.

I just checked GOC database and didn't find any maize gene products,  
are you planning to provide any maize GO annotations to them?

As long as your association files follow the guideline http:// 
www.plantontology.org/docs/otherdocs/assoc-file-format.html, you can  
submit the files any time.
