terms for fruit development stages

[Naama Menda]

I need the following terms for annotating tomato genes expressed during 
different fruit development stages:

-fertilization: The stage of successful pollen germination, penetration, 
and growth of the pollen tube in the stylar tissue towards the ovule and 
into the embryo sac for fusion with the egg cell. Dbxref PMID:12271039

-fruit cell division: The initial stage of fruit development triggered 
in the fruit primordia. Dbxref PMID:12271039

-fruit cell expansion: The stage of increase in cell volume, 
contributing mostly to fruit growth. Dbxref PMID:12271039


Thanks
