Many studies have addressed evolution and phylogeography of plant taxa in oceanic islands, but have primarily focused on endemics because of the assumption that in widespread taxa the absence of morphological differentiation between island and mainland populations is due to recent colonization. In this paper, we studied the phylogeography of Scrophularia arguta, a widespread annual species, in ...

Severe Acute Respiratory Syndrome Coronavirus-2 (SARS-CoV-2) rapidly spread worldwide. The exact mechanisms involved in the pathogenesis of Coronavirus Disease 2019 (COVID-19) are not fully understood. In addition to classical treatment, herbal medicine may effectively manage COVID-19 symptoms and supportive therapy. Scrophularia striata Boiss is a perennial herbaceous plant with immunomodulato...

An evolutionary response to selection requires genetic variation; however, even if it exists, then the genetic details of the variation can constrain adaptation. In the simplest case, unlinked loci and uncorrelated phenotypes respond directly to multivariate selection and permit unrestricted paths to adaptive peaks. By contrast, 'antagonistic' pleiotropic loci may constrain adaptation by affect...
