Mapping gene activity of Arabidopsis root hairs

Table 1 Phenotypes of mutants harboring defects in genes that are preferentially and coexpressed in root hairs

Locus	Gene	Molecular function	Mutant line	Phenotype
At3g49960		Oxidation-reduction process	Salk_119795C	Longer, more frequent root hairs
At1g05240		Peroxidase activity	Salk_10357C	Shorter, irregular, but more frequent root hairs
At2g32270	ZIP3	Zinc-transporter activity	Salk_008709	Shorter, irregular root hairs
At2g25240	CCP3	Serine-type endopeptidase inhibitor activity	Salk_076391; Salk_014163C	Shorter, irregular root hairs
At3g60330	AHA7	Hydrogen-exporting ATPase activity	SALK_042485	Reduced frequency of root hairs [43]
At5g60660	PIP2;4	Water-channel activity	Sail_1251_G12, Sail_535_D05	Longer root hairs [66]
