The electrophysiology of root cells of the marine halophyte, Salicornia bigelovii Torr., has been investigated. Cellular concentrations of K(+), Cl(-), and Na(+) and resulting cell membrane potentials were determined as functions of time and exposure to dilutions of artificial seawater. Treatment of these data by the Nernst criterion suggests that Cl(-) is actively transported into these root c...

Congracilaria babae was first reported as a red alga parasitic on the thallus of Gracilaria salicornia based on Japanese materials. It was circumscribed to have deep spermatangial cavities, coloration similar to its host and the absence of rhizoids. We observed a parasitic red alga with morphological and anatomical features suggestive of C. babae on a Hydropuntia species collected from Sabah, E...

Halophytes classified under the common name of salicornia colonize salty and coastal environments across tidal inundation gradients. To unravel the role of tide-related regimes on the structure and functionality of root associated bacteria, the rhizospheric soil of Salicornia strobilacea (synonym of Halocnemum strobilaceum) plants was studied in a tidal zone of the coastline of Southern Tunisia...

Salicornia spp is one of the most salt-tolerant vascular plants and is native to salt marshes and estuaries. We developed expressed sequence tag derived-simple sequence repeat (EST-SSR) markers for estimating genetic diversity and marker-assisted Salicornia breeding. Six polymorphic EST-SSRs of 40 detected 27 alleles, ranging from three to five alleles per locus. The average number of alleles p...

abstract nowadays, environmental pollution by heavy metals is one of the most serious threats of the world which needs effective remediation actions. the aim of this study was to investigate the potential use of atriplex [atriplex verucifera], salicornia [salicornia europaea] and chenopodium album in simultaneous uptake and accumulation of na and cd or pb in two calcareous soils with different ...

On direct comparison by TLC and IR we established that the alkaloids A-5 and A-4, first isolated from Vinca herbacea W. K . 1 are identical to the oxindole alkaloid majdine (I), later isolated from Vinca major L. 2' 3 and with its isomer isomajdine (II), prepared by heating of (I) in acetic anhydride 2. Based upon some spectroscopic evidence it was claimed2, that majdine was a diastereomer of c...

The tonoplast Na + /H + -antiporter and the tonoplast H + -pumps are essential components of salt tolerance in plants. The objective of this study was to investigate the transport activities of the tonoplast Na + /H + -antiporter and the tonoplast V-H + -ATPase and V-H + -PPase in a highly tolerant salt accumulating halophyte, Salicornia dolichostachya, and to compare these transport activities...
