Q - The Winged Serpent (1982)
The need to understand the mechanisms behind carbon stabilization into slowly cycling pools has become urgent due to the threat of climate change. A major part of global carbon pool is stored belowground in boreal forests, mainly in soil organic matter. However, the mechanisms of soil organic matter transformations, i.e. decomposition and stabilization have not been well identified nor yet described in Earth System Models used to estimate global climate change.
FTA: “The studies confirmed our hypothesis that tannins, abundant plant polyphenolics, and chitin, a polymer present in fungal cell wall, are involved in stabilization of fungal necromass that is highly abundant in soils,” says the lead author of the papers, Dr. Bartosz Adamczyk from Luke. “Furthermore, the field experiments showed that plant roots promote a different soil nitrogen economy with higher concentrations of organic soil nitrogen compared to inorganic soil nitrogen. Taken together, these findings provide a novel framework on how plant roots affect soil organic matter decomposition and stabilization.”

This Type of Algae Absorbs More Light for Photosynthesis Than Other Plants -
FTA: “Although it is known that each cryptophyte has only one type of phycobiliprotein, unique to each species of algae, Richardson and her graduate student Kristin Heidenreich’s recent work suggests that the absorption spectrum of these pigments can shift based on the environment in which the algae grows. “That just blew me away,” Richardson says.
It’s still unclear how the cryptophyte algae accomplish this feat. Richardson suggests that the phycobiliprotein changes shape such that it absorbs different wavelengths. Alternatively, the cryptophytes could be changing the chromophores—the light absorbing chains on the phycobiliprotein complex—so that they are able to absorb whatever color of light that is available to them.
When eukaryotic cells first absorbed the cyanobacteria that became chloroplast—a light-absorbing organelle—photosynthesis became a powerful driver of life on Earth. But the evolution of photosynthesis may not be done yet, as secondary mergers, such as the one that produced cryptophytes, have further expanded the available pigments to capture unused portions of the light spectrum. If plants can continue to harness more and more energy from light, there is no telling how it could affect the future of the planet.“
