The phrase "a speculative scenario in" is correct and usable in written English.
It can be used when discussing hypothetical situations or possibilities within a specific context or framework.
Example: "In a speculative scenario in which technology advances exponentially, society may face unprecedented challenges."
Alternatives: "a hypothetical situation in" or "a conjectural case in".
Considering that the time point for the split between the Strongylocentrotid species and the more recent Parechinid P. lividus species is estimated to be about 35 50 Myr (Smith, 1988), in such a speculative scenario hbox12 may have arisen by a P. lividus lineage-specific duplication from a common ancestor with pmar1.
A description of the optomechanical adopted solution and a speculative scenario to further explore such alien worlds is briefly given.
An alternative approach is to apply a speculative scenario based on the current knowledge on effects of Nereis spp. and Arenicola marina.
In a more speculative scenario, a similar chromatin-mediated signal transduction pathway as for cell cycle control, through for example covalent histone modifications and histone displacement, can be envisaged to inhibit transcription in a compromised genome.
In a currently speculative scenario, subtilases might be involved in processing of peptide hormones that could act as ligands for SGN3/GSO1, promoting formation of a functional cuticle.
Of course, this is a highly speculative scenario requiring further investigation.
Together, these findings lead to an admittedly speculative scenario for the origin and role of the phagocytic capacity in the general context of eukaryogenesis.
One speculative scenario is that defects in epithelial cell polarity could result in the acquisition of a mesenchymal phenotype, giving rise to a gradual parenchymal fibrosis and loss of renal function characteristic of this disorder.
But in those two long-running series, each speculative scenario would be established, and concluded, in an episode or two.
Although such assays do not necessarily reflect in vivo binding, ACS isoforms forming a complex with At-ABI1 and At-FEI2 in principle might physically link At-FLA4 ABA ABA signalling in this speculative scenario.
