“…Increases in shoot-derived carbohydrates have been observed in many plant species in response to low P availability (Foyer and Spencer, 1986;Cakmak et al, 1994;Ciereszko et al, 1996;Ciereszko and Barbachowska, 2000;Morcuende et al, 2007;Mü ller et al, 2007;Lundmark et al, 2010). Increased leaf Suc concentrations lead indirectly to (1) a reduction in photosynthesis through decreased expression of genes encoding many photosystem subunits and small subunits of Rubisco (Lloyd and Zakhleniuk, 2004;Amtmann et al, 2006;Hermans et al, 2006;Rook et al, 2006;Morcuende et al, 2007), (2) an increase in leaf sulfolipid and galactolipid concentrations through the up-regulation of genes involved in their biosynthesis (Dörmann and Benning, 2002;Benning and Ohta, 2005;Gaude et al, 2008), and (3) the production of anthocyanins through a transcriptional cascade involving the transcription factors TTG1-TT8/EGL3-PAP1/PAP2 (Lloyd and Zakhleniuk, 2004;Teng et al, 2005;Amtmann et al, 2006;Solfanelli et al, 2006).…”

“…Phosphate deficiency may either decrease photosynthesis or respiration rate or has no effect on these processes, but alterations in carbon partitioning into starch or sucrose and assimilate transport were often observed (Ciereszko et al 1996Rychter and Rao 2005;Hermans et al 2006). The Pi deficiency-dependent promotions of several reactions in the respiratory carbon metabolism or in photorespiration (and other pathways) were observed (Rychter and Rao 2005); many reactions might require a high activity of specific phosphatases to hydrolyze different phosphorylated substrates (e.g.…”

“…Seedlings, after 7 days of germination, were grown hydroponically on complete nutrient medium (?P, control), medium with 0.1 mM phytic acid (PA) as the only source of phosphorus or without phosphate (-P) as described by Ciereszko et al (1996). Barley plants were cultured in plastic containers (15 seedlings per 5 l of nutrient medium).…”

The morphological and physiological responses of barley to moderate Pi deficiency and the ability of barley to grow on phytate were investigated. Barley cultivars (Hordeum vulgare L., Promyk, Skald and Stratus) were grown for 1-3 weeks on different nutrient media with contrasting phosphorus source: KH 2 PO 4 (control), phytic acid (PA) and without phosphate (-P). The growth on -P medium strongly decreased Pi concentration in the tissues; culture on PA medium generally had no effect on Pi level.

The effect of phosphate starvation on growth and acid phosphatases (APases) localization and activity in oat tissues was investigated. Oat cultivars (Avena sativa L.-Arab, Polar, Szakal) were grown for 1-3 weeks in complete nutrient medium (?P) and without phosphate (-P). Pi concentration in plant tissues decreased strongly after culturing on -P medium. Pi deficit reduced shoot growth, stimulated root elongation and increased ratio of root/shoot in all oat cultivars. Pi deficit had a greater impact on growth of oat cv. Polar than other varieties. A decrease in the internal Pi status led to an increase of acid phosphatase activities in extracts from shoots and roots, and in root exudates. The highest activity of secreted APases was observed for oat cv. Arab, during the third week of growth under Pi-deficient conditions. The activity of extracellular APase was high in young, growing zones of roots of -P plants. Histochemical visualization indicated high activity of APases in the epidermis and vascular tissues of -P plants. Pi deficiency increased intracellular APase activity in shoot mainly in oat cv. Polar, whereas APase activity in roots was the highest in oat cv. Szakal. Protein extracts from roots and shoots were run on native discontinuous PAGE to determine which isoform(s) may be affected by Pi deficiency. Three major APase isoforms were detected in all oat plants; one was strongly induced by Pi deficit. The studied oat cultivars differed in terms of acclimation to deficiency of phosphate-used various pools of APases to acquire Pi from external or internal sources.
