Comparative analysis reveals drought tolerance traits in oak species, suggesting a role for constitutive gene expression over plasticity.

Drought-tolerant oak species exhibit lower gene expression plasticity compared to drought-sensitive species, emphasizing adaptation mechanisms.
The study identified positive selection on constitutive gene expression in drought-tolerant species, revealing evolutionary patterns.
Comparative transcriptomics and trait measurements were used to analyze patterns across six oak species with varied drought tolerances.
Findings indicate that drought-sensitive species show convergent plastic gene expression responses, highlighting evolutionary adaptation nuances.

Mead et al. (2025) studied this question.
