High light activates the xanthophyll cycle and increases the production of reactive oxygen species (ROS), such as hydrogen peroxide (H2O2), but the interrelationships between these parameters is poorly understood. Using a natural freshwater community of algae comprising Euglena species, benthic Navicula diatoms, Chlamydomonas and Chlorella species, Roach et al. demonstrate diurnal variations in H2O2 levels, with a peak at midday. At this point the algae rapidly scavenge H2O2 rather than excreting it
This study examines pectins to understand the changes in cell wall structure associated with the transition from algae to land-plants.
Tons of alternative tree uses! Trees, helping to make the world an even more amazing place.
Would you recognise a desert if it was covered in water? What I mean by that is if somewhere that should be covered in forest were barren and empty, would you notice? A paper in PLOS One…
It is more advantageous for some bromeliads to obtain ant-derived nutrients via its roots than to eat them.
Astaxanthin is nearly as expensive as gold. Unless you grow it in a pond.
17 year old Sara Volz wins $100 000 scholarship from Intel Science Talent Search for her experiment on algae that she kept under her bed.
Although red algae contain green chlorophyll, their red coloration is a result of large amounts of non-green pigments such as phycoerythrin.
DNA content in red algal lineages">Free paper — Estimates of nuclear DNA content in red algal lineages
This paper compiles and discusses all currently available nuclear genome size data for red algae in relation to their most recent taxonomic classification.
Zoë Popper, an Annals of Botany Editor, has a funded PhD position to characterise algal cell walls and make cell wall-directed monoclonal antibodies, using biochemical analysis and immunocytochemistry. The project will also generate and investigate cell wall…
