Plant scientists have used a standard "gene gun" since 1988 to genetically modify crops for better yield, nutrition, pest ...

For a decade, scientists have believed that plants sensed temperature mainly through specialized proteins, and mainly at ...

In this article, you’ll learn how eukaryotic cells operate, providing a solid foundation for understanding how life functions ...

A new UC Riverside-led study reveals how common small particles produced by nature as well as human activities can transform ...

Fourteen cells from the Arabidopsis thaliana plant were imaged every six minutes for about 24 hours as they regenerated their cell walls.The glow shows cellulose, chains of sugar molecules, which ...

Phloem as a long-distance transport system and a habitat for prokaryotic pathogens and piercing-sucking insects. (A) A schematic source-to-sink translocation of metabolite and signaling molecules ...

While prokaryotic cells do not have membrane-bound structures, they do have distinct cellular regions (Figure 1). In prokaryotic cells, DNA bundles together in a region called the nucleoid. Primitive ...

The discovery of PRIMER cells is a major advance to plant biology and further explains the process of plant cell host defense. The PRIMER cell population acts as a source to elicit immunity in cells.

All eukaryotic cells — animal, plant, fungus or protist — have a nucleus that encloses and protects DNA. Nearly all of them ... The theory is supported by recent efforts to uncover the identity of our ...

Animal cells range from 10 to 30 micrometers in length, while plant cells range from 10 and 100 micrometers in length. Animal cells come in various sizes and tend to have round or irregular shapes.
