A new mutant of Arabidopsis disturbed in its roots, right-handed slanting, and gravitropism defines a gene that encodes a heat-shock factor.
A new mutant of Arabidopsis named rha1 is characterized and the gene involved cloned. In roots, the mutant shows minimal right-handed slanting, reduced gravitropic response, notable resistance to 2,4-D, but scarce resistance to IAA and NAA. The roots also show a clear resistance to the auxin transport inhibitors TIBA and NPA, and to ethylene. Other characteristics are a reduced number of latera...
متن کاملA new Arabidopsis thaliana root gravitropism and chirality mutant.
A new Arabidopsis thaliana (L.) Heynh. root mutant, named clg1, was isolated from the Feldmann-Du Pont T-DNA insertional mutagenesis collection. It is characterized by primary roots that make early right-handed coils, show increased right-handed slanting, and reduced positive gravitropism. The mutant roots however did not exhibit increased resistance to IAA, but only a modest increment of resis...
متن کاملPrimary root growth, tissue expression and co-expression analysis of a receptor kinase mutant in Arabidopsis
There is no functional annotation for the majority of the several hundreds of receptor-like kinases in plants. A direct way of inferring the function of these proteins is to study the phenotype that results from loss of function mutants such as T-DNA mutant lines. In this research a function (phenotype) to At2g37050 gene that encodes a receptor like kinase in Arabidopsis T-DNA line was...
متن کاملAUX1 regulates root gravitropism in Arabidopsis by facilitating auxin uptake within root apical tissues.
Plants employ a specialized transport system composed of separate influx and efflux carriers to mobilize the plant hormone auxin between its site(s) of synthesis and action. Mutations within the permease-like AUX1 protein significantly reduce the rate of carrier-mediated auxin uptake within Arabidopsis roots, conferring an agravitropic phenotype. We are able to bypass the defect within auxin up...
متن کاملEIR1, a root-specific protein involved in auxin transport, is required for gravitropism in Arabidopsis thaliana.
The EIR1 gene of Arabidopsis is a member of a family of plant genes with similarities to bacterial membrane transporters. This gene is expressed only in the root, which is consistent with the phenotypes of the eir1 mutants-the roots are agravitropic and have a reduced sensitivity to ethylene. The roots of eir1 mutants are also insensitive to the excess auxin produced by alf1-1 and fail to induc...
