Trifluoperazine, a phenothiazine trnizer and tetracalne, a local anesthetic, have been found to Inhibit a variety of plant hormone responses at concentratons compatible with their known Inhibition of Ca'-calmoduln-dependent enzyme actvities. Among these responses are cytokinindependent betacyanin synthesis and increase In fresh weight InAmarahw tcolor cotyedons, auxin-dependent increase in leng...

The effects of cadmium (Cd; 0.1-1000 μM) and fusicoccin (FC) on growth, Cd(2+) content, and membrane potential (E(m)) in maize coleoptile segments were studied. In addition, the E(m) changes and accumulation of Cd and calcium (Ca) in coleoptile segments treated with Cd(2+) combined with 1 μM FC or 30 mM tetraethylammonium (TEA) chloride (K(+)-channel blocker) were also determined. In this study...

Because fusicoccin (FC) has the the capacity to promote solute uptake, a selective procedure for isolating mutants of Arabidopsis thaliana with a reduced response to the toxin has been developed. The procedure is based on the incubation of A. thaliana seedlings in a solution containing the cation Paraquat (Pq) at a concentration that per se does not produce bleaching of the leaves upon illumina...
