Occurrence of sulfated galactans in marine angiosperms: evolutionary implications. [PDF]

open access: yesGlycobiology, 2004
We report for the first time that marine angiosperms (seagrasses) possess sulfated polysaccharides, which are absent in terrestrial and freshwater plants. The structure of the sulfated polysaccharide from the seagrass Ruppia maritima was determined. It is a sulfated D-galactan composed of the following regular tetrasaccharide repeating unit: [3-beta-D ...

Biotic and abiotic degradation of Δ5-sterols in senescent Mediterranean marine and terrestrial angiosperms.

open access: yesPhytochemistry, 2019
This work used Δ5-sterols and their degradation products to compare the efficiency of biotic and abiotic degradation processes in senescent Mediterranean marine (Posidonia oceanica) and terrestrial (Quercus ilex and Smilax aspera) angiosperms. Type II photosensitized oxidation processes appeared to be more efficient in P. oceanica than in Q. ilex and S.

Anti-Inflammatory Effects of Bioactive Compounds from Seaweeds, Bryozoans, Jellyfish, Shellfish and Peanut Worms

open access: yesMarine Drugs, 2023
Inflammation is a defense mechanism of the body in response to harmful stimuli such as pathogens, damaged cells, toxic compounds or radiation. However, chronic inflammation plays an important role in the pathogenesis of a variety of diseases.

Profiling the cell walls of seagrasses from A (Amphibolis) to Z (Zostera)

open access: yesBMC Plant Biology, 2022
Background The polyphyletic group of seagrasses shows an evolutionary history from early monocotyledonous land plants to the marine environment. Seagrasses form important coastal ecosystems worldwide and large amounts of seagrass detritus washed on ...

Endophytic bacterial community of a Mediterranean marine angiosperm (Posidonia oceanica) [PDF]

open access: yesFrontiers in Microbiology, 2012
Bacterial endophytes are crucial for the survival of many terrestrial plants, but little is known about the presence and importance of bacterial endophytes of marine plants. We conducted a survey of the endophytic bacterial community of the long-living Mediterranean marine angiosperm Posidonia oceanica in surface-sterilized tissues (roots, rhizomes ...

Management and Exploitation of Macroalgal Biomass as a Tool for the Recovery of Transitional Water Systems

open access: yesFrontiers in Ecology and Evolution, 2020
Aquatic angiosperms favor the development of ecosystems services, the welfare of marine organisms and people. Generally, the presence of angiosperms in transitional water systems (TWS) are indicators of good ecosystem status.

Are saltmarshes younger than mangrove swamps?

open access: yesEcology and Evolution, 2022
Temperate saltmarshes and tropical mangrove swamps (mangals) are marine‐influenced, productive ecosystems that enhance nutrient transfers between land and sea and facilitate colonization of lineages between terrestrial and marine habitats.

Facultative Annual Life Cycles in Seagrasses

open access: yesPlants, 2023
Plant species usually have either annual or perennial life cycles, but facultative annual species have annual or perennial populations depending on their environment.

Geochemical characterization of shales of the Eocene Disang Group, Kohima Syncline, India: Inferences to hydrocarbon potential and depositional environment

open access: yesPetroleum Research, 2021
The Kohima Syncline exposes the Eocene Upper Disang Formation in an extensive region that is composed of grey shales with subordinate sandstone and siltstone alterations.

Correlations of life form, pollination mode and sexual system in aquatic angiosperms.

open access: yesPLoS ONE, 2014
Aquatic plants are phylogenetically well dispersed across the angiosperms. Reproductive and other life-history traits of aquatic angiosperms are closely associated with specific growth forms.
