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 ...

Before seedlings can photosynthesize, they depend on fatty acids—and on peroxisomes to process them. Researchers discovered that the protein PEX11 not only helps these structures divide but also ...

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 ...

At first glance, plant and animal cells have a lot in common: they’re both highly organized, keep their DNA tucked away in an envelope, and are kinda juicy inside. But plant cells have evolved some ...

Artistic rendering of cellulose biosynthesis with zoomed in view. Individual cellulose chains (dark brown) are synthesized by plasma membrane-bound (purple) cellulose synthase enzyme complexes (cream) ...
