Phosphate (Pi) and its analog phosphite (Phi) are acquired by plants via Pi transporters. Although the uptake and mobility of Phi and Pi are similar, there is no evidence suggesting that plants can utilize Phi as a sole source of phosphorus. Phi is also known to interfere with many of the Pi starvation responses in plants and yeast (Saccharomyces cerevisiae). In this study, effects of Phi on pl...

Phosphate (Pi) deficiency is a common nutritional stress of plants in both agricultural and natural ecosystems. Plants respond to Pi starvation in the environment by triggering a suite of biochemical, physiological, and developmental changes that increase survival and growth. The key factors that determine plant sensitivity to Pi starvation, however, are unclear. In this research, we identified...

phosphorus (p), in the form of phosphate ion (pi), is a vital element contributing in biomolecule structures, metabolic reactions, signaling pathways and energy transfer within the living cells. the objective of the present study was to assess the influence of fungal infection on pi metabolism in compare to the effects of phosphate stress in arabidopsis. quantification of total p contents showe...

Enhanced root hair production, which increases the root surface area for nutrient uptake, is a typical adaptive response of plants to phosphate (Pi) starvation. Although previous studies have shown that ethylene plays an important role in root hair development induced by Pi starvation, the underlying molecular mechanism is not understood. In this work, we characterized an Arabidopsis mutant, hp...

The phosphate signal transduction (PHO) pathway, which regulates genes in response to phosphate starvation, is well defined in Saccharomyces cerevisiae. We asked whether the PHO pathway was the same in the distantly related fission yeast Schizosaccharomyces pombe. We screened a deletion collection for mutants aberrant in phosphatase activity, which is primarily a consequence of pho1(+) transcri...

The aim of this work was to analyse the effects of different growth conditions (phosphate and contemporary carbon-phosphate starvation) on polystyrene adhesion of a strain of Pseudomonas aeruginosa ATCC 27853 and its four phenotypic mutants during experimental growth in starvation conditions. Bacterial adhesion was measured at 20, 40, 60 and 720 min. Data obtained showed that growth conditions ...

the objective of this study was to evaluate the impact of short-term starvation and re-feeding on oxidative stress in mesopotamichthys sharpeyi (günther, 1874). after two weeks adaptation to new conditions, a total number of 270 fingerlings were distributed into nine 300-l fiberglass tanks, equipped with aeration system in three treatments including 4, 8 and 16 days starvation (each in 3 replic...
