Growing plant cells assemble a strong yet extensible nanofibrillar structure on their surface, the primary cell wall, which physically limits cell growth and defines cell size and shape. In this ...

Plants are colonized by microorganisms from various kingdoms of life that have beneficial, neutral or detrimental effects on plant productivity. Microorganisms residing on the leaf surface, referred ...

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 ...

These meristems contain stem cells that divide as needed and form new cells that develop into specialized tissue. Using the example of plant roots, the researchers have now been able to decipher which ...

Scientists have created a new atlas of plant cells during immune response, in turn discovering a new rare cell state, called Primary IMmunE Responder (PRIMER), that acts as an immune response hub to ...

Researchers have produced the most detailed map yet of how stem cells in the growing tip of a plant begin their journey to form the many cell types that shape flowers and stems. They identified 18 ...

The sunlight-collecting organelles known as chloroplasts solve a packing problem: how to optimize photosynthesis without sustaining damage from dangerously intense rays. Living on light is a dangerous ...

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) ...
