At calcium and phosphate concentrations within ranges commonly encountered in soil solutions, increasing calcium concentration in flowing culture solutions markedly increased phosphate absorption by several annual legumes. Calcium increased phosphate uptake relatively more at low than at high phosphate concentration. The effect of calcium was greater for two Medicago species than for two cultivars of Trifolium subterraneum and is suggested as at least a partial explanation for the greater sensitivity of Medicago to soil acidity and its greater tolerance to soil alkalinity than Trifolium subterraneum. Pretreatment at different calcium levels had no effect on phosphate absorption, while transfer to solutions of different calcium levels caused an immediate response in phosphate uptake. These results indicate that calcium had a direct effect on phosphate absorption, rather than an indirect effect through root morphology or anatomy. It is suggested that calcium increased phosphate absorption by screening electronegative charges on the roots, thus increasing the accessibility of absorption sites to phosphate.

ABSTRACT The histone deacetylase Rpd3p functions as a transcriptional repressor of a diverse set of genes, including PHO5. Here we describe a novel role for RPD3 in the regulation of phosphate transporter Pho84p retention in the cytoplasmic membrane. We show that under repressing conditions (with Pi), PHO5 expression is increased in a pho4Δ rpd3Δ strain, demonstrating PHO regulatory pathway independence. However, the effect of RPD3 disruption on PHO5 activation kinetics is dependent on the PHO regulatory pathway. Upon switching to activating conditions (without Pi), PHO5 transcripts accumulated more rapidly in rpd3Δ cells. This more rapid response correlates with a defect in phosphate uptake due to premature recycling of Pho84p, the high-affinity H+/PO4 3− symporter. Thus, RPD3 also participates in PHO5 regulation through a previously unidentified effect on maintenance of high-affinity phosphate uptake during phosphate starvation. We propose that Rpd3p has a negative role in the regulation of Pho84p endocytosis.
