Appears in the following schemes

Hormone pathway

Protein function

Encodes an ent-copalyl diphosphate synthase involved in gibberellin biosynthesis.

Phenotype

Multiple mutant:
co;fca;ga1 triple mutant never flowers under neither SD nor LD conditions. [Reeves et al., 2001]

Single mutant:
ga1 single mutant is late flowering under both SD and LD conditions. ( the late-flowering phenotype is stronger under SD conditions.) [Wilson et al., 1992][Rieu et al., 2008]

Function:
Catalyzes the conversion of geranylgeranyl diphosphate to the gibberellin precursor ent-copalyl diphosphate. [Data from UniProt]
