Immunolocalization of Na+/K+-ATPase and Na+/K+/2Cl- cotransporter in the tubular epithelia of sea snake salt glands.
The sublingual salt gland is the primary site of salt excretion in sea snakes; however, little is known about the mechanisms mediating ion excretion. Na(+)/K(+)-ATPase (NKA) and Na(+)/K(+)/2Cl(-) cotransporter (NKCC) are two proteins known to regulate membrane potential and drive salt secretion in most vertebrate secretory cells. We hypothesized that NKA and NKCC would localize to the basolater...
متن کاملProgress in Studying Salt Secretion from the Salt Glands in Recretohalophytes: How Do Plants Secrete Salt?
To survive in a saline environment, halophytes have evolved many strategies to resist salt stress. The salt glands of recretohalophytes are exceptional features for directly secreting salt out of a plant. Knowledge of the pathway(s) of salt secretion in relation to the function of salt glands may help us to change the salt-tolerance of crops and to cultivate the extensive saline lands that are ...
متن کاملWall protuberance formation and function in secreting salt glands of Tamarix aphylla L
Salt glands of Tamarix aphylla consist of three pairs of secretory cells arranged one upon the other. At the stage of secretion, the upper and middle pair of secretory cells develop in their walls an internal system of anastomosed rods, the protuberances. In the formation of the wall protuberances, Golgi vesicles and microtubules appear to participate. The stage of salt secretion is also charac...
متن کاملCorrelation of Na+,K+-ATPase content and plasma membrane surface area in adapted and de-adapted salt glands of ducklings.
During salt-water adaptation, an increase occurs in Na+,K+-ATPase content and surface area of the basolateral plasma membrane of the principal cell of the duck salt gland. To determine the degree to which these changes are correlated, accepted morphometric methods were used to determine numerical cell densities and plasma membrane surface densities of peripheral and principal cells. After adapt...
