Salinity and periodic inundation controls on the soil-plant-atmosphere continuum of gray mangroves
2017
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-exchanges and nutrient availability. Salinity, in particular, can be considered one of the main abiotic regulating factors for halophytes and salt tolerant species, due to its influence on water use patterns and growth rate. Ecohydrological literature has rarely focused on the effects of salinity on plant transpiration, based on the fact that the terrestrial plants mostly thrive in low saline, unsaturated soils where the role of osmotic potential can be considered negligible. However, the effect of sal…
Fungal community assemblage of different soil compartments in mangrove ecosystem
2017
AbstractThe fungal communities of different soil compartments in mangrove ecosystem are poorly studied. We sequenced the internal transcribed spacer (ITS) regions to characterize the fungal communities in Avicennia marina root-associated soils (rhizosphere and pneumatophore) and bulk soil compartments. The rhizosphere but not pneumatophore soil compartment had significantly lower fungal species richness than bulk soil. However, bulk soil fungal diversity (Shannon diversity index) was significantly higher than both pneumatophore and rhizosphere soil compartments. The different soil compartments significantly affected the fungal community composition. Pairwise sample analyses showed that bulk…
Farinomalein derivatives from an unidentified endophytic fungus isolated from the mangrove plant Avicennia marina
2012
Five farinomalein derivatives including three new compounds, farinomaleins C–E (3–5), and one new isoindoline congener (6) were isolated from an unidentified endophytic fungus obtained from the inner tissues of healthy leaves of the mangrove plant Avicennia marina from Oman. The structures of the new compounds were unambiguously elucidated on the basis of their mass, as well as one and two dimensional NMR spectroscopic data.
