Gene : PLS A. thaliana

DB identifier  ? AT4G39403 Secondary Identifier  ? locus:1009023321
Name  ? POLARIS Brief Description  polari
TAIR Computational Description  polari;(source:Araport11)
TAIR Curator Summary  Encodes a 36 amino acid polypeptide that is necessary for correct responses to cytokinins and auxins, correct cell expansion in the root, and for vascular patterning in the leaf. Mutation of PLS results in an enhanced ethylene-response phenotype, defective auxin transport and homeostasis, and altered microtubule sensitivity to inhibitors.

Type Comment Proteins
PLS_ARATH developmental stage First observed in embryos from the heart stage and throughout embryo development, restricted to the basal part, constituting the developing radicle. During the curled cotyledonary stage, strongly expressed in the radicle and detectable in the cotyledons. On germination, mostly present in root tips, but also at low levels in the cotyledons and hypocotyl. In flowering plants, restricted to the root tip and to the silique wall.
PLS_ARATH function Required for correct root growth and vascular development, probably by modulating both cell division rate in meristems and cell elongation in roots. Negative regulator of the ethylene signaling pathway that modulates microtubule cytoskeleton dynamics and auxin transport and homeostasis, and possibly cytokinin signaling, thus influencing root growth and lateral root development.
PLS_ARATH similarity Belongs to the POLARIS peptide family.
PLS_ARATH tissue specificity Mostly expressed in the embryonic root from the heart stage and in the seedling primary and lateral root tips, especially in the columella initials and lateral root cap. Also detectable in aerial parts of the seedling, sepals and leaves, principally in vascular tissues of the lamina and petiole.
