  • Transport of inorganic phosphate inPseudomonas

    Inorganic phosphate transport by wild-typePseudomonas aeruginosa cells grown in a phosphate-limited medium involves a biphasic process. The uptake obeys Michaelis-Menten kinetics with respective apparentK m values of 1.1 μM and 10 μM for the high- and low-affinity systems. These systems may be also differentiated by their sensitivity to osmotic shock, by their specificity towards phosphite ...

  • Functional PTB phosphate transporters are present ... -

    Two inorganic phosphate (Pi) uptake mechanisms operate in streptophytes and chlorophytes, the two lineages of green plants. PHOSPHATE TRANSPORTER B (PTB) proteins are hypothesized to be the Na + /Pi symporters catalysing Pi uptake in chlorophytes, whereas PHOSPHATE TRANSPORTER 1 (PHT1) proteins are the H + /Pi symporters that carry out Pi uptake in angiosperms.

    In contrast, transcription of PHO87 and PHO90, encoding the low-affinity H(+)/P(i) transport system, is independent of phosphate status. In the present work, we reveal that, upon P(i) starvation, these low-affinity P(i) transporters are endocytosed and targeted to the vacuole.

    Introduction. Phosphorus (P) is an essential macronutrient for plant growth and development. However, in most soils, the concentration of phosphate (Pi) is limiting due to its low solubility and mobility (Raghothama, 1999).Pi deficiency commonly impairs plant growth and affects ∼70% of cultivated land globally (Hinsinger, 2001; Cakmak, 2002; López-Arredondo et al., 2014).

    Potassium transport and signaling in Arabidopsis. In root cells, after perception of external low K + stress, plants generate some signal molecules (e.g., Ca 2+, reactive oxygen species (ROS)) that regulate downstream K + channels and transporters at transcriptional and post-translational levels. The red dots represent Ca 2+ ions. AKT1, HAK5, and KUP7 are all involved in K + uptake.

    Phosphate acquisition and transport are the key processes for efficient symbiotic N fixation in legumes (Nussaume et al., 2011; Gu et al., 2015; Sulieman and Tran, 2015). In a soybean, GmPT5, a high-affinity Pi transporter has been shown to transport Pi from roots to nodules, especially under conditions of limited P (Qin et al., 2012).

Plants can absorb P as dissolved orthophosphate (Pi, inorganic phosphorus, mainly in the form of H 2 PO 4 2−) which is highly immobile and bound to soils causing a widespread P deficiency for plant production [].In order to grow under such P-limiting conditions plants have evolved several ...
