General information

Mutant name ahg3-1
Mutant/Transgenic plant mutant
Ecotype Col-0
Mutagenesis type other
Dominant/Recessive/Semi-dominant recessive
PMID 16339800
CommentThe ahg3-1 plants grew slightly slower than wild-type plants on soil, but the final plant size was the same as the wild type. The bolting time was also slightly delayed.

Mutated genes

Locus name Alias Hormone Mutated site Paper description
AT3G11410 AHG3 abscisic acid This mutation causes the amino acid change of Gly-287 to Glu in the predicted gene product. encodes a protein phosphatase 2C (PP2C), a negative regulator in ABA signaling
