Phenotype

Defective in directional cell elongation processes; abnormal cortical microtubule function; exhibits right-handed helical growth in longitudinally expanding organs such as roots, etiolated hypocotyls, stems, petioles, and petals; twisting phenotype is most apparent in lateral organs (cotyledons, rosette leaves, and petals), when the plant is viewed from above, these organs are twisted in a counterclockwise direction; the counterclockwise twisting of rosette leaves and cotyledones is caused by right-handed helical growth of epidermal cell files in petioles; epidermal cell files of hypocotyl and stem in dark-grown plants also form constitutive right-handed helices; allelic to two classic twisting mutants, tortifolia1 and convoluta.
