SAM restructuring suggestion

[Leonore Reiser]

Pankaj

Now that there are terms that define stages of plant development- could 
these mutants be annotated to 'reproductive stage'
so in PATOese
that might be something like 
entity:reproductive stage
attribute: timing
value: early or late?

Ill hopefully get a chance to talk to Sean May from NASC at the Arabidopsis 
meeting and see what he thinks about their annotations as well and maybe 
compare notes on flowering time mutant annotation.
