One thread of the story began many years ago with geneticists' studies of their standard laboratory organism, the Drosophila fruit fly.

Little was influential in promoting the mouse as a laboratory organism.

It has been one of the most common laboratory organisms in some part because it was thought to be particularly safe to use.

This amoeba was easily cultivated and became a widely distributed and studied laboratory organism.

Of the only two other animal genomes sequenced so far, the roundworm has 19,000 genes and the fruit fly, also a standard laboratory organism, 13,000.

They are also used as laboratory organisms for a variety of studies, especially involving seasonal endocrine variation.

Phodopus species have developed into important laboratory organisms.

The fruit fly has been a standard laboratory organism for 80 years, but only 2,000 of its genes have been well described.

He spent four years searching for strains of yeast, a common laboratory organism, that lived longer than others.

She has also been able to reverse the damage, at least in laboratory organisms, by inserting genes that counteract synuclein.
