Active Anti-erosion Protection Strategy in Tamarisk (Tamarix aphylla)
Plants have numerous active protection strategies for adapting to complex and severe environments. These strategies provide endless inspiration for extending the service life of materials and machines. Tamarisk (Tamarix aphylla), a tree that thrives in raging sandstorm regions, has adapted to blustery conditions by evolving extremely effective and robust erosion resistant characteristics. Howev...
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 کاملHydrolyzable Tannins of Tamaricaceous Plants. 7.1 Structures and Cytotoxic Properties of Oligomeric Ellagitannins from Leaves of Tamarix nilotica and Cultured Tissues of Tamarix tetrandra.
Partially unacylated new oligomeric hydrolyzable tannins, nilotinin T2 (1, trimer) and nilotinin Q1 (2, tetramer), together with four known trimers, nilotinin T1 (3) and hirtellins T1-T3 (4-6), and a dimer, tamarixinin B (7), were isolated from the aqueous acetone extracts of leaves of Tamarix nilotica. Among them, the new trimer 1 and the known trimers 4 and 6, in addition to the partially una...
متن کاملPhysiological Responses of Tamarix ramosissima to Extreme NaCl Concentrations
Hydrologic alterations of river systems in western North America over the past century have increased soil salinity, contributing to the establishment and spread of an introduced halophytic species, Tamarix ramosissima (Ledeb.). The physiological responses of Tamarix ramosissima to salinity stress are incompletely known. To assess the salinity tolerance of this species, we measured several whol...
متن کاملA new ferulic acid ester and other constituents from Tamarix nilotica leaves.
Phytochemical investigation of the leaves of Tamarix nilotica (Tamaricaceae) has led to isolation of methyl ferulate 3-O-sulphate (1) for the first time from natural sources. In addition, coniferyl alcohol 4-O-sulphate (2), kaempferol 4'-methyl ether (3), tamarixetin (4) and quercetin 3-O-beta-D-glucupyranuronide (5) were isolated from the n-butanol soluble fraction of the extract. The pentacyc...
