A Small Plant's Genome Has Huge Impact

Back to article | Note about images

the plant Arabidopsis thaliana and background representing DNA sequence

In the foreground of this image is the plant Arabidopsis thaliana, the subject of an international genome-sequencing project that was successfully completed in the year 2000. The DNA-sequencing screen in the background produces the images that allow researchers to see nucleic acid sequences. Each color represents one of the four base chemicals that make up DNA: A (adenine), G (guanine), C (cytosine) and T (thymine).

Arabidopsis plants in a growth facility

Salk scientist (Justin Zimmerman) tends to Arabidopsis plants in a high throughput growth facility used for propagation of insertion mutants. Seeds collected from these Salk lines have been distributed throughout the world by the Arabidopsis Biological Resource Center at Ohio State University.
