Example sentences for: dormancy
How can you use “dormancy” in a sentence? Here are some example sentences to help you improve your vocabulary:
Well-studied examples include the promotion of fruit ripening by ethylene, regulation of the cell cycle by auxin and cytokinin, induction of seed germination and stem elongation by GA, and the maintenance of seed dormancy by ABA.
Diapausing embryos of the orthopteran Austroicetes cruciata undergo slow development for the first two months of diapause, before entering a resting stage [ 24 ] . Similarly, caterpillars of Cirphus unipunctata and Laphygma exigua continue to feed and develop during diapause, albeit at a much-reduced rate [ 25 ] , and caterpillars of the corn-stalk borer Sesamia nonagriodes undergo non-stationary moults during diapause [ 26 ] . These examples hint that the expression of diapause-controlled dormancy may vary between species [ 2 ] . Consequently, diapause could be considered extreme regulation of developmental rate, rather than a shutting down of morphological development.
In immature B cells, activation through the BCR induces either a state of unresponsiveness, termed anergy, or death by apoptosis, depending on the physical nature and concentration of the antigen [ 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 ] . In some B cell lymphomas, activation through the BCR can induce cell cycle arrest and apoptosis in vitro and tumor dormancy in vivo [ 19 26 27 28 ] . The core of the multi-subunit BCR is membrane-bound immunoglobulin (mIg), which is non-covalently associated with two co-receptor molecules, CD79a (Igα) and CD79b (Igβ), products of the mb-1 and B29 genes [ 29 30 ] . The biochemical changes induced by engagement of the BCR are extensive and include an increase in tyrosine phosphorylation of several intracellular proteins, hydrolysis of membrane phospholipids, fluxes in the concentration of intracellular free Ca 2+, activation of several serine/threonine kinases including components of the MAP kinase pathway, and changes in the activities of a panel of transcription factors.
Bacterial endospores are a prime example of resistant dormancy structures, and recent research indicates that such dormant forms of bacteria can survive for even millions of years, under appropriate conditions.
If dormancy structures similar to endospores were produced at some point by life forms on Mars, data reported here suggest they could still be present and viable.
