Claim

Population-genetic analyses of 318 Salicornia accessions identified a contrasting chromosome-6A signal between two species and highlighted an OSCA calcium-permeable channel gene as a candidate locus for osmotic adaptation.

Assessment

Supported

Score: 0.9212 under ledger-default@0.3.0 at snapshot 27745

2 of 4 review checks done · 1 counted · 1 by the author only

Main unresolved issue: 6 counted evidence items have no independence review; repeats of one origin may be counted as several coverage:3385b15a-c548-8297-9d76-9958c3cd0439

Not yet independently audited.Evidence reviewed so far supports this claim, but only 1 of 4 review checks has been done.A quoted passage from phys.org was not found on the page when Galedra fetched it.

Why?

Strongest counted support: The study reports a chromosome-6A population-genetic contrast and identifies an OSCA channel gene as a candidate osmotic-adaptation locus. weight 2.000000 evidence

Suppressed as dependent: The excerpt directly reports 318 accessions, a contrasting chromosome-6A signal between two species, and an OSCA channel candidate for osmotic adaptation.

Review gaps: qualifiers reviewed, opposing search done, independence reviewed

What would most change this: One independent, direct measurement that contradicts this claim would move it from Supported to Leans supported.

How the number was reached

Each counted link is weighed by multiplying the factors the model declares; a factor it does not declare is not shown. Every factor name below links to what that number means.

Under neighbouring settings of the same model: 0.8483 to 0.9607, a spread of 0.1124.

Half-even rounding, six places for weights and four for the probability. The same inputs under the same model reproduce this exactly; that is what the trace hash above is for. How a score is worked out explains every factor, why it is there, and what the model sets it to.

Inferences

Concluded from

None.

Used as a premise in

None.

An inference is interpretation, not evidence: it never changes the assessment of its conclusion. Each premise is a claim with its own evidence.

Threads

None. Threads are for disagreements about how a determination was made — a statement whose figures are not in the passage it rests on, two sources that may share an origin. Something about the world belongs in the evidence above.

Claim edges

None. Edges are stored and displayed; v0.1 does not propagate probability across them.
