Selected items of wheat variation - from palaeobotany to molecular biology

open access: yesActa Societatis Botanicorum Poloniae, 2014
The usefulness of data on ecotypes of wheat as well as of information about distribution of genes of hybrid necrosis for an interpretation of some questionable detections of fossil materials is emphasized.

Pteris madhusoodananii (Pteridaceae), a new fern species from India

open access: yesNordic Journal of Botany, EarlyView.
Pteris madhusoodananii sp. nov. (Pteridaceae), from the Kolli hills of Eastern Ghats, India, is described. The new taxon is morphologically distinct, characterized by a unique lamina texture and coloration, specific pinna‐pinnule architecture and distinct spore micromorphology.

Progress in bone tissue engineering biomaterials: Development, challenges, and prospects

open access: yesVIEW, EarlyView.
Scheme 1 Application of biomaterials in immunomodulation during bone tissue engineering. Abstract Bone defect repair remains a major clinical challenge in orthopedics. Over 2 million cases caused by trauma, tumors, and other factors occur annually, with large‐scale defects posing a particular bottleneck due to limited self‐healing capacity.

Sensory Biology of the Franciscana (Pontoporia blainvillei, Pontoporiidae, Cetartiodactyla): Ontogenetic Modifications of Vibrissae and Vibrissal Crypts

open access: yesIntegrative Zoology, EarlyView.
The transition of cetaceans from a terrestrial to an aquatic environment involved a crucial sensory adaptation to environments with limited visibility. Vibrissae, important mechanoreceptors, undergo an ontogenetic transformation in odontocetes. This research describes the histomorphology of vibrissae and crypts at different developmental stages ...

Modelling Patterns of Past Inundation Processes Combining Geoarchaeology and Morphometric Hydrological Analysis in the Shashe‐Limpopo Basin, South Africa

open access: yesArchaeometry, EarlyView.
ABSTRACT Riverine and valley systems across the globe have been central to the development of past urban centres. By AD 900, the Shashe and Limpopo Rivers seem to have facilitated the interaction and integration of early farming communities in southern Africa. This paper focuses on the application of geoarchaeological perspectives made available by the

A phylogenomic approach for a new infrageneric classification of Bulbostylis (Abildgaardieae, Cyperaceae)

open access: yesJournal of Systematics and Evolution, EarlyView.
In this study, we investigate the relationships among 149 species of Bulbostylis (Cyperaceae)—representing 69% of global diversity—using a universal probe kit for targeted genomic sequencing of flowering plants (Angiosperms353 probe kit). Our sampling also includes the genus Nelmesia, which we found to fall within Bulbostylis.

Hydraulic Activation of Stomata Induced by Hygroscopic Fertilizer Salts Alters Crop Carbon–Water Exchange: Field Evidence From Cereal Crops

open access: yesPlant, Cell &Environment, EarlyView.
ABSTRACT Hydraulic activation of stomata (HAS), driven by hygroscopic salt films on leaf surfaces, can create an additional pathway for water loss beyond conventional stomatal vapour diffusion, yet this process remains largely overlooked in studies of plant–atmosphere interactions.
