1. TRANSPORTE E HOMEOSTASE Na+/K+ SOB CONDIÃÃES DE SODICIDADE EM FEIJÃO CAUPI / Na+ and K+ transport and homeostasis under sodicity conditions in cowpea
High soil salinity can be associated with K+ starvation enabling interactive stresses on plant nutrition that impair crop production. The transport mechanisms on the soil-root symplast-xylem boundaries are crucial to the establishment of Na+ toxicity under salt stress, especially under low K+ availability. Then, the aim of this work was the physiological cha

2. Changes in K, Rb, and Na Transport to Shoots after Anoxia 1
The effect of anoxia on subsequent uptake and transport of K, Rb, and Na was examined with seedlings of barley (Hordeum vulgare L.), corn (Zea mays L.), and tall fescue (Lolium × Festuca hybrid derivative) to further our understanding of xylem loading. Roots were incubated in solutions depleted of O2 by flushing with N2 gas. After 1 hour exposure, plants we

3. Protection of Plasma Membrane K+ Transport by the Salt Overly Sensitive1 Na+-H+ Antiporter during Salinity Stress1
Physicochemical similarities between K+ and Na+ result in interactions between their homeostatic mechanisms. The physiological interactions between these two ions was investigated by examining aspects of K+ nutrition in the Arabidopsis salt overly sensitive (sos) mutants, and salt sensitivity in the K+ transport mutants akt1 (Arabidopsis K+ transporter) and
