Populus euphratica is a plant model intensively studied for elucidating physiological and molecular mechanisms of salt tolerance in woody species. Several studies have shown that vacuolar potassium (K+) ion channels of the two-pore K+ (TPK) family play an important role in maintaining K+ homeostasis. Here, we cloned a putative TPK channel gene from P.(More)
eATP mediates cellular K + and Na + homeostasis in two contrasting poplar species differing in salt tolerance. Using the non-invasive micro-test technology (NMT), the effects of extracellular ATP (eATP) on salt-altered flux profiles of K+, Na+, and H+ were investigated in salt-tolerant poplar species, Populus euphratica and salt-sensitive P. popularis.
