Scientists have identified one of the earliest multicellular algae. Their new method could help unlock much more information from Precambrian fossils.
A polysaccharide found in the cell walls of land plants has now been found outside the cell. This chemical, Xyloglucan, could be one of clues as to how plants moved onto land.
For International Women’s Day 2017, we asked plant biologist Dr Zoë Popper to write about a typical day in her working life. Here, she reflects on the importance of diversity in her job.
This week Nigel Chaffey finds he has a vision problem that needs more than a trip to the optician.
The changing colour of Greenland could have consequences for the rest of the planet.
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.
