Low temperature development of winter rye leaves alters the detergent solubilization of thylakoid membranes.

abstract：:With the aid of an extracellular vibrating electrode, natural electric fields were detected and measured in the medium near growing roots and root hairs of barley seedlings. An exploration of these fields indicates that both the root as a whole, as well as individual root hairs, drive large steady currents through the...
