Reactive oxygen species (ROS) produced naturally during cellular metabolism often cause oxidative damage to cells. However, these molecules also play an important role in normal cellular signaling.

Interestingly, the ketolation reaction necessary to produce these ketocarotenoids is only performed in nature by a few species of algae and microorganisms 8. Examples of natural producers include the ...

Imagine if our bodies could grow new organs throughout our entire lives. Plants do this constantly, thanks to tiny, powerful reservoirs of stem cells. But how do these cells know when to divide, and ...

In a groundbreaking study on the synthesis of cellulose -- a major constituent of all plant cell walls -- a team has captured images of the microscopic process of cell-wall building continuously over ...

Plant cytokinesis culminates in the formation of a new cell wall between daughter cells, a process distinguished by the assembly and guided expansion of the phragmoplast, a microtubule–actin scaffold ...
