Long‐distance pollen transport mediated by migratory hoverflies

Ecography, EarlyView.
Long‐distance animal migrations shape ecosystems by redistributing nutrients, connecting populations, and mediating ecological interactions. However, the ecological contributions of many abundant insect migrants remain poorly quantified. Hoverflies are among the most numerous migratory insects and highly efficient pollinators, suggesting that their ...

Extracellular vesicles derived from edible plants and edible fungi: Compositional characteristics, engineering strategies and biofunctions

Food Biomacromolecules, EarlyView.
Non‐animal extracellular vesicles as bioactive‐compound carriers: compositional characteristics, engineering strategies, and biofunctions. Abstract Animal‐derived extracellular vesicles (EVs) were widely used for bioactive compound delivery but constrained by complex origins, potential immunogenicity, and pathogen contamination.

Combining phenotypic, physiological, and multi‐omics studies to provide new insights on the role of 2,4‐epibrassinolide in regulation of seed shattering in Elymus sibiricus L.

Grassland Research, EarlyView.
Abstract Background Seed shattering limits the production of Elymus sibiricus L., and application of exogenous brassinosteroid significantly alleviates plant organ abscission. Methods To explore the potential regulatory network of brassinosteroid on seed shattering, the abscission zone of E. sibiricus cv. Lanyu No.

Pollen Morphology of Crucianella L. (Rubiaceae) Based on Light and Scanning Electron Microscope Data and Implications for Taxonomy

Microscopy Research and Technique, EarlyView.
This study provides the palynological analysis of 12 Crucianella L. taxa using LM and SEM. Variations in pollen size, aperture number, and exine ornamentation were identified as key traits, demonstrating their taxonomic value for distinguishing closely related species and subspecies within the genus. ABSTRACT Crucianella L.

Pollen types of Sapindaceae from Brazilian forest fragments: apertural variation [PDF]

Acta Botânica Brasílica
Morphological variations in angiosperm pollen grains may aid in the differentiation of families, genera and species. Sapindaceae pollen morphology holds promise for the recognition of taxa of this cosmopolitan family, which is well distributed in ...

Pollen morphology of Scorzonera (Asteraceae) in Turkey

Phytotaxa, 2016
The pollen morphology of 45 taxa belonging to 15 sections of the genus Scorzonera distributed in Turkey were studied with light and electron microscopies. The pollen is generally 3-zonocolporate. Pollen grains are oblate-spheroidal with the polar axes 23.2–59.2 µm and the equatorial axes 27–62.5 µm.
