The phrase "a direct interplay" is correct and usable in written English.
It can be used to describe a clear and immediate interaction or relationship between two or more elements or factors.
Example: "The study revealed a direct interplay between environmental factors and species behavior."
Alternatives: "a clear interaction" or "an immediate relationship".
The control of inducible expression is a direct interplay between the repressor concentration, effector concentration and the binding constant of the operator.
As shown previously, we reported a direct interplay between the HPV16 E2 and E6/E7 proteins.
The action of XC_0249 thus represents a direct interplay between cyclic mononucleotide and cyclic dinucleotide signalling (Supplementary Figure S5).
A direct interplay between cellular and molecular events occurring post-BCG is illustrated by the IL-6/IL-10 ratio being a prognostic marker of tumor recurrence (Fig. 1).
Their budding relationship grew in the style of a Lubitsch film -- a look here and there, as tuxedoed waiters swirled by and glamorous interruptions kept them from much direct interplay.
One area where Smith could have dug deeper is in discussing the Godfather's direct interplay with competing artists at his peak, as well as how he dealt with the notion of becoming an aging musician while watching Michael Jackson and others take bits of his panache and find commercial success.
The known deleterious impact of HSV2 infection on HIV disease progression has been at least in part linked to direct interplay between the two viruses [10].
We use these homologous sequence datasets to directly compare genetic structure between the two parasite populations, to contrast selective forces acting upon the two genes, and to examine any evidence of direct interplay between the two species in this setting of mesoendemic, sympatric transmission among two geographically defined parasite populations sharing the same human hosts.
These experiments, although not conclusive, provide the first suggestion of direct interplay between the WhiG- and WhiA-dependent parts of the sporulation regulatory cascade, previously thought to be separate (Chater, 1998; Flärdh et al., 1999).
Taken together, these reports clearly demonstrate that execution of cell-cycle arrest does not require the direct interplay of cyclins, CDKs and CDK-inhibitors and that this indirect arrest may not restricted to any specific phase of the cell cycle.
We give a characterization of those geometric interval-configurations which allow Fourier spectra directly in terms of the self-adjoint extensions of the minimal operator D. This allows for a direct and explicit interplay between geometry and spectra.
