plantlet formation

[J Clark]

Hi,

I am working on some terms in the gene ontology consortium process 
ontology. They are the two terms pasted below and I am wondering whether 
they ought to have parentage under 'response to hormone' and if so then 
which hormone? Is there anybody out there who has expert knowledge of 
these two processes and who could tell me which hormones cause these two 
processes to occur? I am having trouble finding a paper with this 
information.

Thanks,

Jennifer Clark
