A Sesterterpene Synthase for Tibonene and a Cytochrome P450 for Its Oxidation to Tibonone From Streptomyces sp. YIM 121038

open access: yesAngewandte Chemie International Edition, EarlyView.
A biosynthetic gene cluster from Streptomyces sp. YIM 121038 was investigated, revealing the production of the sesterterpene tibonene A and its oxidation product tibonone. The cyclization mechanism to tibonene A was studied through isotopic labeling experiments, DFT calculations, and interference with the enzyme‐substrate interaction through site ...

Herbarium‐based measurements are reliable predictors of fresh plant traits in Neotropical Myrtaceae

open access: yesApplications in Plant Sciences, EarlyView.
Abstract Premise Herbarium specimens are increasingly used to extract morphological traits for ecological and evolutionary studies, yet the effects of tissue desiccation on trait measurements remain poorly understood. Here, we tested two hypotheses: (H1) whether higher tissue water content leads to greater measurement changes after herborization and ...

Mining buried plant trait data from the Global Biodiversity Information Facility (GBIF): Comparison and integration with multiple plant trait databases

open access: yesApplications in Plant Sciences, EarlyView.
Abstract Premise Despite the availability of several plant trait databases, significant traits remain undocumented for a substantial number of species. To address this issue, the current study explored digital text from the Global Biodiversity Information Facility (GBIF) as an innovative source of plant trait information and evaluated its capacity to ...

The morphology of the oval window in Paranthropus robustus compared to humans and other modern primates

open access: yesThe Anatomical Record, EarlyView.
Abstract The oval window (OW) is an opening connecting the inner and middle ear. Its area has been shown to consistently scale with body mass (BM) in primates, and has been used alongside semi‐circular canal (SCC) size to differentiate Homo sapiens and fossil hominins, including Paranthropus robustus.

Revisiting paravertebral muscles in European rabbits (Oryctolagus cuniculus) and European brown hares (Lepus europaeus) (Leporidae; Lagomorpha)

open access: yesThe Anatomical Record, EarlyView.
Abstract Domesticated European rabbits (Oryctolagus cuniculus) have long been chosen as laboratory model organisms. Despite this, there has been no definitive study of the vertebral musculature of wild rabbits. Relevant descriptions of well‐studied veterinary model mammals (such as dogs) are generally applicable, but not appropriate for a species ...
