As an associate professor at Rockefeller University, Coruzzi identified key genes controlling the assimilation of inorganic nitrogen into key amino acids used for nitrogen transport in plants.

Katze's team will seek to learn more about the nature of the 1918 flu by inserting key genes from the killer flu into a common flu strain.

Until now, scientists had been able to create mice missing a key gene, but the animals lacked the gene in every cell where it was normally active.

One of these studies found that the variation in 11 key genes had an impact on wolf vision, sense of smell, hearing, coat color, metabolism, and immunity.

The portion of human DNA analyzed and sequenced by Rowen, Hood and Koop and their colleagues holds some of the key genes involved in the body's immune system.

In 1980, Christiane Nusslein-Volhard and Eric Wieschaus at the European Molecular Biology Laboratory in Heidelberg, Germany, identified key genes involved in establishing the body plan of fruit flies.

The USDA / Delta project, under Dr . Melvin Oliver, a Department of Agriculture researcher in Lubbock, Texas, involves a tricky balance of suppressing and then releasing key genes.

SF-1 is a critical regulator of reproduction, regulating the transcription of key genes involved in sexual development and reproduction, most notably TDF to up-regulate transcription of the Sox9 gene.
39.
During mouse embryonic development, Nodal, a transforming growth factor-beta superfamily ligand, is a key gene involved in patterning both the anterior-posterior axis and the left-right axis of the early embryo.
40.
However, sometimes a mutation will occur in a particular cell in a key gene and the result will be that the gene will be either switched on or switched off.
