Journal ArticleDOI
Photosynthetic responses of Halophila ovalis (R. Br.) Hook. f. to osmotic stress
TL;DR: Although recovery from osmotic stress was demonstrated, the extreme treatments resulted in premature senescence of the entire leaf and petiole, and recovery was not possible, and photosynthetic pigments thus confirmed the chlorophyll fluorescence responses.
Journal ArticleDOI
Radiative energy budget reveals high photosynthetic efficiency in symbiont-bearing corals
Kasper Elgetti Brodersen,Mads Lichtenberg,Peter J. Ralph,Michael Kühl,Michael Kühl,Daniel Wangpraseurt +5 more
TL;DR: Corals appear as highly efficient light collectors with optical properties enabling light distribution over the corallite/tissue microstructural canopy that enables a high photosynthesis QE of their photosynthetic microalgae in hospite.
Journal ArticleDOI
The Genome of a Southern Hemisphere Seagrass Species (Zostera muelleri)

TL;DR: In this article, the assembly and characterization of the Zostera muelleri genome was reported, a southern hemisphere temperate species, a seagrass that evolved from land plants but returned to the sea around 140 million years ago during the early evolution of monocotyledonous plants.
Journal ArticleDOI
Seagrass-Mediated Phosphorus and Iron Solubilization in Tropical Sediments
Kasper Elgetti Brodersen,Klaus Koren,Maria Moßhammer,Peter J. Ralph,Michael Kühl,Michael Kühl,Jakob Santner +6 more
TL;DR: This work shows that tropical seagrass mobilize phosphorus and iron within their rhizosphere via plant-induced local acidification, leading to dissolution of carbonates and release of phosphate, and via local stimulation of microbial sulfide production, causing reduction of insoluble Fe(III) oxyhydroxides to dissolved Fe(II) with concomitant phosphate release into the rhizospheric porewater.
Journal ArticleDOI
Hybrid life-cycle assessment of algal biofuel production.
TL;DR: Overall, the supply chain of bio-crude is more sustainable than that of conventional crude oil and will offer carbon sequestration opportunities as the production process is net carbon-negative.
