THE polar lipid fractions from blue-green algae are usually simpler than those from higher algae and leaves, and normally contain only those four acyl lipids that are commonly associated with ...

“The blueprint that nature gives us is that eukaryotes acquire nitrogen fixation by endosymbiosis.” Thus, studying the relationship between photosynthetic algae and their nitrogen-fixing endosymbionts ...

bigelowii for essential functions like amino acid and pyrimidine biosynthesis and for nitrogen fixation. “Seeing flavodoxin in there was really surprising,” Coale said. Flavodoxin is a redox protein ...

The discovery of how a critical enzyme "hidden in nature's blueprint" works sheds new light on how cells control key processes in carbon fixation ... also called blue-green algae—to maximize ...

This “greening” of the water column has caused decreased levels of dissolved oxygen (DO) in bottom waters as planktonic algae die and ... to global nitrogen fixation rates is generally ...

nitrogen and mercury from urban and agricultural sprawl. The lake in particular has been besieged by nutrient pollution for decades, causing unprecedented blooms of blue-green algae. Also known as ...

The nitroplast evolved from a nitrogen-fixing blue-green bacterium (cyanobacterium) which, through a series of evolutionary adjustments, has become an integral part of the algae’s cellular ...
