Cation/proton exchangers (CAXs) are a class of secondary energised ion transporter that are being implicated in an increasing range of cellular and physiological functions. CAXs are primarily Ca(2+) efflux transporters that mediate the sequestration of Ca(2+) from the cytosol, usually into the vacuole. Some CAX isoforms have broad substrate specificity, providing the ability to transport trace ...

BACKGROUND AND AIMS Osmolytes are low-molecular-weight organic solutes, a broad group that encompasses a variety of compounds such as amino acids, tertiary sulphonium and quaternary ammonium compounds, sugars and polyhydric alcohols. Osmolytes are accumulated in the cytoplasm of halophytic species in order to balance the osmotic potential of the Na(+) and Cl(-) accumulated in the vacuole. The a...

This study elucidated O2 dynamics in shoots and roots of submerged Halosarcia pergranulata (Salicornioideae), a perennial halophytic stem succulent that grows on floodprone mudflats of salt lakes. Oxygen within shoots and roots was measured using microelectrodes, for plants when waterlogged or completely submerged, with shoots in light or in darkness, in a controlled environment. Net photosynth...

Abstract Background Suaeda glauca ( S. ) is a halophyte widely distributed in saline and sandy beaches, with strong saline-alkali tolerance. It also admired as landscape plant high development prospects scientific research value. The chloroplast (cp) genome has recently been reported; however, the mitochondria (mt) still unexplored. Results mt of were assembled based on reads from Pacbio Illumi...

The ability of some halophytic plants such as Chenopodium quinoa to sequester large quantities salt into epidermal bladder cell (EBC) is considered one the traits conferring their salinity stress resilience. In current study, we used mRNA-seq characterize transcriptome differences between intact and EBC-free leaves from that were treated with 400 mM NaCl for 4 weeks. Employing K-means clusterin...

Plant responses to salinity stress are reviewed with emphasis on molecular mechanisms of signal transduction and on the physiological consequences of altered gene expression that affect biochemical reactions downstream of stress sensing. We make extensive use of comparisons with model organisms, halophytic plants, and yeast, which provide a paradigm for many responses to salinity exhibited by s...

Halophytes have long been used for medicinal purposes. However, many decades, their use was entirely empirical, with virtually no knowledge of the bioactive compounds underlying different applications. In recent growing problem antibiotic resistance triggered research on alternative antimicrobial approaches, and halophytes, along other plants, regained attention as an underexplored pharmacologi...
