To study the potential role of potassium channels in the taste response to potassium salts, we applied 4-aminopyridine (4-AP) to the anterior rat tongue and recorded chorda tympani nerve taste responses to chemical stimuli. 4-aminopyridine is a pharmacological blocker that reduces potassium conductance through potassium channels in nerve and muscle.(More)
Embryogenic callus was obtained from young petiole, stem, and root explants of 4-year-old Siberian ginseng plants on medium supplemented with 2,4-dichlorophenoxyacetic acid. Embryogenic callus differentiated into somatic embryos (SEs), most of which could germinate but developed abnormally. Friable embryogenic callus was induced mainly from the root regions(More)
