Alteration in phosphate uptake potential of wheat plants co-cultivated with salicylic acid.
The phosphate uptake potential was significantly stimulated with low concentration of salicylic acid (SA). In one of the wheat cultivars (Triticum aestivum Var. Sonalika), 50 microM SA stimulated phosphate (PO(4)(3-)) uptake. At higher concentrations of SA (500 and 1000 microM), the rate of uptake was reduced. These findings underscore the light and dose-dependent biphasic action of SA: a low 50 microM stimulated, and high concentrations 500 and 1000 microM inhibited, PO(4)(3-) uptake.
