The rise of microbial cheaters in iron-limited environments: Study reveals their evolutionary history

Competition and cooperation are fundamental forces that govern the evolutionary and ecological dynamics among species. The balance between these forces varies across ecological contexts, with some environments favoring cooperative behaviors that promote mutual benefit, while others reward competitive strategies that maximize individual fitness.

Researchers uncover 'parallel universe' in tomato genetics

In a paper appearing in Science Advances, Michigan State University researchers have unraveled a surprising genetic mystery centered on sugars found in what gardeners know as "tomato tar."

#GeneRegulation couples transfers of information to transfers of mass and energy. The E. coli Trp-operon is often used as a simple example of gene reg. Genetic info transfers from #DNA to #proteins, including the synthesis of (1) a #repressor gene. In absence of tryptophan, the #operon induces the synthesis of the #metabolic #enzymes for its production (2). Tryptophan then binds the repressor (3)...
