tropism
These differences include their infectivity in host cells, virulence and pathogenesis in animal models, drug sensitivity, tissuetropism, morphology, and antigenic composition.
From theCambridge English Corpus
The 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 Corpus
These vectors can efficiently transduce dividing and nondividing cells and have broad tissuetropism.

From theCambridge English Corpus
The virus exhibits multiple cell tropisms, infecting peripheral blood mononuclear cells and skin cells before establishing latency in sensory neurons.
From theCambridge English Corpus
The transmission route could even be linked to host specificity and virulence or tissuetropism.
From theCambridge English Corpus
The incentives for these tropisms, again, are too complex to summarize here.

Topics 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.

Urbanczyk (1996, 2000) formalises this implicit assumption by appealing to the notion of 'tropism', which is used in referring to edges.

Cunningham (1956) described the tropisms (taxes) of various stages of this same nematode, observing the direction of migration in inclined closed tubes.
