It's no secret that pollen plays a vital role in plant reproduction worldwide, including the production of food. But for decades, scientists have been puzzled about the variety of patterns on the ...

In angiosperms, pollen wall pattern formation is determined by primexine deposition on the microspores. Here, we show that AUXIN RESPONSE FACTOR17 (ARF17) is essential for primexine formation and ...

It's spring! Everything is turning green. And yellow. Thursday was the vernal equinox, the first day of spring. Just about everywhere you look these days in my neighborhood, and maybe yours too, there ...

From pollen forecasting, honey analysis and climate-related changes in plant-pollinator interactions, analysing pollen plays an important role in many areas of research. Microscopy is still the gold ...

For millions of people with seasonal allergies, springtime means runny noses, excessive sneezes and itchy eyes. And, as with many things, climate change appears to be making allergy season even worse.

They are very tiny, but they are a key source of information when it comes to Earth's evolutionary history: pollen grains are usually no larger than 20 micrometers, or 0.02 millimeters. Using these ...

Pollen from 18,000 tropical plants was digitized in Panama. The images will be used to train a machine-learning model to identify pollen grains, as part of the PollenGEO project Elisabeth King A team ...

Smithsonian researcher Ingrid Romero studies fossil pollen to reconstruct ancient climates and predict future changes Erin Wunderlich Researcher Ingrid Romero holds a case full of pollen slides at the ...
