General information

Mutant name axr6
Mutant/Transgenic plant mutant
Ecotype Col-0
Mutagenesis type DEB
Dominant/Recessive/Semi-dominant semi-dominant
PMID 10654597 12839993
Commentaxr6-1 and axr6-2 homozygous plants are seedling lethal. Less severely affected in all aspects of axr6-2 heterozygote phenotype than axr6-1.

Mutated genes

Locus name Alias Hormone Mutated site Paper description
AT4G02570 AUXIN RESISTANT 6(AXR6); CULLIN 1(CUL1) auxin The mutations result in substitution of phenylalanine with valine and isoleucine in axr6-1 and axr6-2, respectively
AT4G02570 AXR6,CUL1 jasmonic acid substitution of phe at 111th aa to val (axr6-1) or to Ile (axr6-2)
