Mangroves are woody plants which form the dominant vegetation in tidal, saline wetlands along tropical and subtropical coasts. The current knowledge concerning the most striking feature of mangroves i.e., their unique ability to tolerate high salinity is summarized in the present review. In this review, we shall discuss recent studies that have focused on morphological, anatomical, physiological, biochemical, molecular and genetic attributes associated with the response to salinity, some of… 

Mangroves: obligate or facultative halophytes? A review

Evaluations of the aforementioned evidence suggest that mangroves are obligate halophytes, as well as the physiological mechanisms that allow maintenance of function under fluctuating salinity conditions should be strengthened in future research.

Response of mangrove plant species to a saline gradient: Implications for ecological restoration

The potential of using mangrove species for rehabilitation of high saline environments by revealing the capacities of species to remove salt from sediment is investigated by revealing A. marina to be the most efficient in retaining salt within plant tissues while C. tagal is superior to R. mucronata but inferior to A.marina in performing this function.

Molecular adaptation to salinity fluctuation in tropical intertidal environments of a mangrove tree Sonneratia alba

This study elucidates the mechanism of high-salt adaptation in mangroves at the whole-transcriptome level by salt gradient experimental treatments and reveals that several candidate genes (including salt-related genes, TF-encoding genes, and PSGs) and major pathways are involved in adaptation to high-Salt environments.

Anatomical and physiological adaptation of mangrove wetlands in east coast of Tamil Nadu

The mangrove adaptations in the environment are the majority essential for the sustainable survival, development and intertidal zones due to special ability of salt tolerance. Mangroves possess a

Mangrove root: adaptations and ecological importance

This review briefly depicts adaptive strategies of mangrove roots with respect to anatomy, physiology, biochemistry and also the major advances recently made at the genetic and genomic levels.

Salinity Tolerance in Plants: Mechanisms and Regulation of Ion Transport

A wider, more detailed understanding of salt tolerance in plants mediated by ion transport is achieved, to understand present and future ways to modify and manipulate ion transport and salinity tolerance and also to find natural limits for the modifications.

Osmotic and hydraulic adjustment of mangrove saplings to extreme salinity.

Results show that mangroves confront and partially ameliorate acute salinity stress via simultaneous reductions in Ψs, gs and Kplant, thus developing synergistic physiological responses at the cell and whole-plant scales.

Salinity and periodic inundation controls on the soil‐plant‐atmosphere continuum of gray mangroves

Salinity and periodic inundation are both known to have a major role in shaping the ecohydrology of mangroves through their controls on water uptake, photosynthesis, stomatal conductance, gas

Adaptive Mechanisms of Halophytes and Their Potential in Improving Salinity Tolerance in Plants

The potential of improving salt tolerance in crop plants by introducing candidate genes related to antiporters, ion transporters, antioxidants, and defense proteins from halophytes for conserving sustainable agriculture in salinity-prone areas is discussed.

SALT/WATER RELATIONSHIPS IN MANGROVES

The aim of the present review is to summarize the current knowledge concerning the mechanisms underlying the most striking feature of mangroves—their unique ability to obtain water from the surrounding sea.

Salinity tolerance in halophytes.

Halophytes, plants that survive to reproduce in environments where the salt concentration is around 200 mm NaCl or more, constitute about 1% of the world's flora and research should be concentrated on a number of 'model' species that are representative of the various mechanisms that might be involved in tolerance.

Generation and analysis of expressed sequence tags from the mangrove plant, Acanthus ebracteatus Vahl

Some of these clones, including putative mannitol dehydrogenase, plastidic aldolase, secretory peroxidase, ascorbate peroxIDase, and vacuolar H+-ATPase, may be related to osmotic homeostasis, ionic homeostasia, and detoxification.

Physiological responses of the mangrove Rhizophora mangle grown in the absence and presence of NaCl.

Energy-dispersive X-ray microprobe analyses on root vacuoles of control plants reveal Na+ preference, on those of salt treated plants a strong K+ preference and Vacuolar K+ concentrations are neither affected by NaCl nor do they vary across the root radius.

Osmotic adaption in Australian mangroves

Young and old leaves of twenty-three mangrove species from northern Queensland (Australia) were investigated for their mineral ion and organic solute content. With a few exceptions, the Na+ and the

Arbuscular mycorrhizal relations of mangrove plant community at the Ganges river estuary in India

Intensity of AM colonization varied both with the species and situations of their occurrence, being more intense and also more extensive in less saline dry ridge mangrove than in more saline formative and developed swamp mangroves.

Photosynthetic and Stomatal Responses of the Grey Mangrove, Avicennia marina, to Transient Salinity Conditions.

Stomatal conductance changed such that the intercellular CO(2) concentration measured under normal atmospheric conditions occurred in the transition between the lower, linear and upper nonlinear portions of the A(c(i)) curve, indicating a reduction in the capacity for CO( 2) assimilation which recovered upon return to the original salinity.
