A study suggests that several species of brown algae may have independently evolved to express both sexes simultaneously, and it’s likely that female algae evolved male traits—not the other way around.

The largest waterlily species in the world was incorrectly classified for more than 170 years.

While the higher temperatures and CO₂ levels associated with climate change currently fuel plant productivity, a study finds that changing conditions could take a toll on photosynthesis rates in regions outside the Arctic within a decade.

The growing season on the tundra is starting earlier as the planet warms, but the plants aren’t sequestering more carbon, a new study finds.

A seagrass relies on symbiotic bacteria inside its roots to fix nitrogen. This is the first time scientists have demonstrated that this relationship occurs in a marine plant.

Researchers can now explain how some marine plants obtain their nitrogen.

Record-breaking rainfall has caused widespread flooding and devastation in Queensland and New South Wales, forcing the closure of some university campuses.

Canada has ordered 76 million doses of Covifenz, the main ingredient of which was manufactured in the leaves of a tobacco relative.

The dual purposes of the plants’ hidden colors may conflict as the climate warms, authors of a new study suggest.

Scientists warn that climate change–induced early flowering could have negative effects on wildlife, agriculture, and gardening.

Whole genome sequences reveal multiple domestications of this agriculturally important tree and may hold the secrets to producing the sweet fruit year round.

Elaborate annotations hidden in a copy of Sir James Edward Smith’s The English Flora hinted at the life of a mysterious woman botanist.

A look back at some of the articles we most enjoyed reading, writing, and editing this year

The first reference-quality genome for this grass species could aid managers in understanding and eradicating this highly invasive plant.

An analysis of more than half a million trees reveals that many species begin to taper off seed production once they hit a certain size.

A study finds that plants sharing the same growth medium can exchange microRNAs that silence genes in the recipient, suggesting the nucleic acids may act as signaling molecules.

Spores found in 480 million-year-old rock bring the fossil record in line with molecular estimates of when plants first adapted to life on land.
