Root hairs are tubular outgrowths that originate from epidermal cells. Exposure of Arabidopsis to cadmium (Cd) and arsenic [arsenite, As(III)] increases root hair density and length. To examine the underlying mechanism, we measured the expression of genes involved in fate determination and morphogenesis of root hairs. Cd and As(III) downregulated TTG1 and GL2 (negative regulators of fate determ...
Directional transport of the phytohormone auxin is required for the establishment and maintenance of plant polar growth. Natural auxins, primarily indole 3-acetic acid (IAA), are ampipathic weak acids that diffuse into membrane bilayers when protonated, suggesting that polar auxin movement is primarily established at the point of cellular efflux. However, recent evidence indicates that proton-c...
