Flowers at times host abundant and specialized communities of bacteria and fungi that
influence floral phenotypes and interactions with pollinators. Ecological processes drive …

Highlights•Microbial sharing is central for microbiomes in the pollination system.•Local
network architecture determines potential dispersal routes.•Species filtering however limits …

Floral nectar is prone to colonization by nectar-adapted yeasts and bacteria via air-, rain-,
and animal-mediated dispersal. Upon colonization, microbes can modify nectar chemical …

Anthropogenic activities are triggering global changes in the environment, causing entire
communities of plants, pollinators and their interactions to restructure, and ultimately leading …

The movement of pollen grains from anthers to stigmas, often by insect pollinator vectors, is
essential for plant reproduction. However, pollen is also a unique vehicle for viral spread …

While bee–angiosperm mutualisms are widely recognized as foundational partnerships that
have shaped the diversity and structure of terrestrial ecosystems, these ancient mutualisms …

Plant–microbe associations are ubiquitous, but parsing contributions of dispersal, host
filtering, competition and temperature on microbial community composition is challenging …

Highlights•Several floral traits are associated with pollinator-related microbe transmission.•
Beneficial and pathogenic microbes may share some transmission constraints.•Plant and …

Microbes associated with flowers and leaves affect plant health and fitness and modify the
chemical phenotypes of plants with consequences for interactions of plants with their …

Solitary bees are subject to a variety of pressures that cause severe population declines.
Currently, habitat loss, temperature shifts, agrochemical exposure, and new parasites are …
