Mutated genes
Mutated Gene 1 Locus name AT1G59750 Alias ARF1 Organism Arabidopsis thaliana Description Encodes a member of the auxin response factor family. ARFs bind to the cis element 5'-TGTCTC-3' ARFs mediate changes in gene expression in response to auxin. ARF's form heterodimers with IAA/AUX genes. ARF1 enhances mutant phenotypes of ARF2 and may act with ARF2 to control aspects of maturation and senescence.
Mutated Gene 2 Locus name AT5G62000 Alias ARF2/HSS/ORE14 Organism Arabidopsis thaliana Description Encodes an auxin response factor. Mutants have many defects including enlarged rosette leaves, reduced fertility, later senescence, hypocotyl elongation defects, enlarged seeds and enlarged cotyledons. May not mediate auxin effects. Increase in seed size due to increased cell proliferation.
