...nce a person is infected, these viruses can remain dormant for long periods within white blood cells before they burst out and begin replicating. This reactivation of the virus boosts the number of cells infected thereby increasing the chances that the cells will become cancerous.

Their spores a dormant stage in the creatures' life cycle inhabit virtually every surface water source, becoming active microsporidia once they have been ingested by an animal susceptible to infection by that particular species.

... acid levels are low, and ppGpp tells a cell to go dormant until amino acid levels return to normal. "But there was something missing from the ppGpp story," Artsimovitch said. "We knew that ppGpp had a dramatic effect on gene expression, but for some reason that effect was drastically decreased when ...New insight into cancer metastasis
...tions no longer are necessary, and it soon becomes dormant in most tissues throughout the rest of an organism's life. Through a process that still is somewhat unclear to researchers, tumor cells reactivate this long-dormant protein and thereby acquire the ability to move throughout the body. ...Study probes ecosystem of tree holes

As a first step, researchers cross-pollinated dormant weedy strains of rice with non-dormant domesticated strains to develop populations segregating for dormancy. Then they determined some classical genetic attributes, such as heritability associated with several populations segregating for dormancy. "...
