Examplesoftropism
tropismThese differences include their infectivity in host cells, virulence and pathogenesis in animal models, drug sensitivity, tissuetropism, morphology, and antigenic composition.From theCambridge English CorpusThe molecular basis for receptorbinding specificity and the role this plays in viraltropismand host range is not as clear-cut as is often portrayed.From theCambridge English CorpusThese vectors can efficiently transduce dividing and nondividing cells and have broad tissuetropism.From theCambridge English CorpusThe virus also has gastrointestinaltropismin various bird species.From theCambridge English CorpusThe virus exhibits multiple cell tropisms, infecting peripheral blood mononuclear cells and skin cells before establishing latency in sensory neurons.From theCambridge English CorpusThe transmission route could even be linked to host specificity and virulence or tissuetropism.From theCambridge English CorpusThe incentives for these tropisms, again, are too complex to summarize here.From theCambridge English CorpusTopics covered include: energy flow, water relations, mineral nutrition, translocation, growth, hormones, cell growth and differentiation, vegetative and reproductive development, photomorphogenesis, tropisms and resistance to stress.From theCambridge English CorpusUrbanczyk (1996, 2000) formalises this implicit assumption by appealing to the notion of 'tropism', which is used in referring to edges.From theCambridge English CorpusRolls rejects this definition since he wishes to eliminate taxes, tropisms, and reflexes.From theCambridge English CorpusCunningham (1956) described the tropisms (taxes) of various stages of this same nematode, observing the direction of migration in inclined closed tubes.From theCambridge English CorpusYet bacteria of all those colonies communicate fortropismin shared tasks, coordinated activities and exchange of relevant genetic bacterial information using biochemical communication of meaning-bearing semantic messages.From theCambridge English CorpusHowever, this is not a form oftropism, but a nastic movement, a similar phenomenon.FromWikipediaThis example is from Wikipedia and may be reused under a CC BY-SA license.The difference is that tropisms are influenced by the direction of their stimulus, while nastic movements are not.FromWikipediaThis example is from Wikipedia and may be reused under a CC BY-SA license.One of the nucleotide mutations is in the process of glycoprotein formation and affectstropism.FromWikipediaThis example is from Wikipedia and may be reused under a CC BY-SA license.These examples are from corpora and from sources on the web.
