Germplasm Phenotype:

• ARR22 KO  — There are no detectable phenotypic differences between this mutant and wild-type plants grown under normal conditions
• ARR22 KO ARR24 KO  — There are no consistently detectable phenotypic differences between this double mutant and wild-type plants grown under normal conditions.
• arr22-2  — This mutant does not have any defects in vegetative development. Careful examinations of arr22-2 and wild type plants reveal no noticeable difference in chalazal cell morphology or size, embryonic development, silique dry weight, or silique inorganic ion, carbohydrate, or amino acid content.
• arr22-3  — This mutant does not have any defects in vegetative development. Careful examinations of arr22-3 and wild type plants reveal no noticeable difference in chalazal cell morphology or size, embryonic development, silique dry weight, or silique inorganic ion, carbohydrate, or amino acid content.
