Myosin XIK of Arabidopsis thaliana Accumulates at the Root Hair Tip and Is Required for Fast Root Hair Growth
Myosin motor proteins are thought to carry out important functions in the establishment and maintenance of cell polarity by moving cellular components such as organelles, vesicles, or protein complexes along the actin cytoskeleton. In Arabidopsis thaliana, disruption of the myosin XIK gene leads to reduced elongation of the highly polar root hairs, suggesting that the encoded motor protein is i...
متن کاملSociety of Hair Testing guidelines for drug testing in hair.
The Society of Hair Testing (SoHT) Guidelines for Drug Testing in Hair provide laboratories with recommended best practice guidelines whether they are currently offering drug testing in hair, or plan to offer a hair testing service in the future. The guidelines include reference to recommended sample collection and storage procedures, through sample preparation, pre-treatment and analysis and t...
متن کاملRoot Hair Mutants of Barley
Almost sixty mutants with shortened or reduced root hairs or without root hairs at all have been isolated among 2000 M1 plant progenies (20.000 M2 seeds) of the spring barley cultivar “Lux” after sodium azide mutagenesis. One group of 25 mutants show fairly stable phenotype while 33 lines have unstable, indistinct or segregating phenotypes. The mutants were selected after 3 to 4 days growth in ...
متن کاملMDR-like ABC transporter AtPGP4 is involved in auxin-mediated lateral root and root hair development.
Previous data have suggested an involvement of MDR/PGP-like ABC transporters in transport of the plant hormone auxin and, recently, AtPGP1 has been demonstrated to catalyze the primary active export of auxin. Here we show that related isoform AtPGP4 is expressed predominantly during early root development. AtPGP4 loss-of-function plants reveal enhanced lateral root initiation and root hair leng...
متن کاملThe Arabidopsis root hair mutants der2-der9 are affected at different stages of root hair development.
Root hairs are an excellent model system to study cell developmental processes as they are easily accessible, single-celled, long tubular extensions of root epidermal cells. In a genetic approach to identify loci important for root hair development, we have isolated eight der (deformed root hairs) mutants from an ethylmethanesulfonate (EMS)-mutagenized Arabidopsis population. The der lines repr...
