Key messageThisreviewgivesacomprehensiveoverviewofadaptationsofmangroverootsystemtotheadverseenvironmentalconditionsandsummarizestheecologicalimportanceofmangroveroottotheecosystem.AbstractIn plants, the first line of defense against abiotic stress is in their roots. If the soil surrounding the plant root is healthy and biologically diverse, the plant will have a higher chance to survive in stressful conditions. Different plant species have unique adaptations when exposed to a variety of… 

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.

Metagenomics of Bacterial Communities Associated with the Halophytic Plant

Soil associated with plants host various microorganisms. These microbial communities interact with plants to adopt biotic and abiotic stresses promoting plants growth and development. These


Under saline regimes, both species adapted specific characteristics of the roots and stems for better survival under saline environments.

Coping with Saline Environment: Learning from Halophytes

Salt stress is a crucial barrier to crop growth, development, and production and hence negatively affects food security globally. In addition, the current trends of climate change increase the

Diversity, function and assembly of mangrove root-associated microbial communities at a continuous fine-scale

The divergence in the diversity and function of root-associated microbial communities along a continuous fine-scale niche is revealed, thereby highlighting a strictly selective role of soil-root interfaces in shaping the fungal community structure in the mangrove root systems.

Unraveling hydrogen sulfide-promoted lateral root development and growth in mangrove plant Kandelia obovata: Insight into regulatory mechanism by TMT-based quantitative proteomic approaches.

The results revealed that H2S could contribute to the morphogenesis of the unique root system of mangrove plant K. obovata, and play a positive role in the adaption ofMangrove plants to intertidal habitats.



Salt tolerance mechanisms in mangroves: a review

A general picture of salt tolerance mechanisms of mangroves is given, thus providing a new avenue for development of saltolerance in crop plants through effective breeding strategies and genetic engineering techniques.

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.

Anatomical Adaptive Strategies to Flooding and Rhizosphere Oxidation in Mangrove Seedlings

The findings suggest that the differential tolerance to waterlogging in mangrove seedlings is not simply based on their ability to oxidise the rhizosphere; the high diffusive resistance in the hypocotyl junction is likely to affect root aeration when the plant's access to air is limited by partial or total submergence.

Flooding: abiotic constraint limiting vegetable productivity

Various morpho-physiological, biochemical and anatomical changes induced in root system during flooding, for example reduction in the shoot-root relative growth, Formation of thicker adventitious roots or air roots, arenchyma formation and cuboidal packing of cells enhances the longitudinal transport of gases.

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.

Cell wall adaptations to multiple environmental stresses in maize roots.

A municipal solid-waste bottom slag was used to grow maize plants under various abiotic stresses and to analyse the structural and chemical adaptations of the cell walls of various root tissues to find out the role of phi thickenings in the rhizodermis in the oldest part of the seminal root.

Isolation and Expression Analysis of Novel Silicon Absorption Gene from Roots of Mangrove (Rhizophora apiculata) via Suppression Subtractive Hybridization

Silicon is mainly observed in the epidermal roots' cell walls of mangrove plants compared to other parts, and the expression of a candidate gene of serine-rich protein was shown by RT-PCR and real-time qRT-PCRs.

Physiological and proteomic characterization of salt tolerance in a mangrove plant, Bruguiera gymnorrhiza (L.) Lam.

Results revealed that salt tolerance under 200 mM NaCl treatment was due to effective osmotic adjustment, accumulation of inorganic ions as well as increased expression of photosynthesis-related proteins and antioxidant enzymes, which improved the salt tolerance of B. gymnorrhiza, and furthermore promoted plant growth.

Hormonal interplay during adventitious root formation in flooded tomato plants.

Treatment with the ethylene biosynthesis inhibitor aminoethoxyvinylglycine (AVG) and the auxin transport inhibitor 1-naphthylphthalamic acid (NPA) resulted in a reduction of AR formation in waterlogged plants, and it was observed that ethylene, perceived by the Never Ripe receptor, stimulated Auxin transport.
