Some flowers use a clever strategy to ensure effective pollination by bees, doling out pollen gradually from two different sets […]

Researchers warn that if we don’t act quickly, many species, including species of salmon and southern resident killer whales, are likely to be functionally extinct in the next 25 years.

ANIMATION University of Copenhagen researchers have discovered how mosses became one of our planet’s most widely distributed plants — global wind systems transport them along Earth’s latitudes, to rooftops, sidewalks, and lawns worldwide, and as far away as Antarctica. This new knowledge can provide us with a better understanding of […]

Almond trees are at full bloom in late February. Most almond fields have two or more varieties within the field and require cross pollination by bees.

Leipzig is host to the oldest botanical garden in Germany. On an area of only three hectares, around 6500 of the 350,000 plant species worldwide grow here. Credit: Swen Reichhold Leipzig could mean for the future of plant taxonomy what Greenwich meant for world time until 1972: it could become […]

Genes that give plant nucleus its shape discovered, also regulate copper tolerance. Researchers at the University of Tokyo have identified how the architecture of the cell nucleus can change gene activity in plants. This discovery reveals fundamental knowledge about genome regulation and points towards future methods for potentially manipulating the […]

The capacity of the Amazon forest to store carbon in a changing climate will ultimately be determined by how fast trees die – and what kills them. Now, a huge new study has unraveled what factors control tree mortality rates in Amazon forests and helps to explain why tree mortality […]

A recent study examining carbon storage in Pacific Northwest forests demonstrated that although large-diameter trees (21 inches) only comprised 3% of total stems, they accounted for 42% of the total aboveground carbon storage. The researchers highlight the importance of protecting large trees and strengthening existing forest management policies so that […]

Progeny of novel combination is more vigorous and productive than parental plants. Novel grafted plants — consisting of rootstock epigenetically modified to “believe” it has been under stress — joined to an unmodified scion, or above-ground shoot, give rise to progeny that are more vigorous, productive, and resilient than the […]

Rubisco is the most abundant enzyme on the planet. Present in plants, cyanobacteria (also known as blue-green algae) and other photosynthetic organisms, it’s central to the process of carbon fixation and is one of Earth’s oldest carbon-fixing enzymes. Researchers at UC Davis and LBNL have now discovered an alternative form […]
