Abortive transcription is when RNA Polymerase makes short transcripts, typically shorter than 10 nucleotides (nt), while still bound at the promoter.

GA synthesis starts in plastids, leads to the production of a linear precursor molecule geranylgeranyl diphosphate or GGPP 20C, which gets converted into ent-kaurene. This compound is oxidized in ER, leading to GA12, Dioxygenase enzymes in the cytosol are able to oxidize GA12 to all other gibberellins in pathways
