New insights into regulation of root initiation

When young, dark-grown seedlings of thale cress are given light, they start to form roots from the stem-like part of the plant called the hypocotyl. Abdellah Lakehal used this system to study how the initiation of these adventitious ...

Investigating the rise of oxygenic photosynthesis

About 2.4 billion years ago, at the end of the Archean Eon, a planet-wide increase in oxygen levels called the Great Oxidation Event (GOE) created the familiar atmosphere we all breathe today. Researchers focused on life's ...

New method takes analysis of genetic libraries to next level

Uppsala researchers have developed a new method for investigating dynamic processes in large genetic libraries. By using this method to study cell cycle regulation,researchers can paint a clearer picture of the elusive control ...

Into the molecular eye: Investigating liquid samples in real time

Biofilms are integral to Earth's ecology and the sustainability of life. Made up of microorganisms, biofilms play vital roles in recycling life's most essential elements. But a lack of versatile analytical tools has made ...

Study uncovers a plant barrier against toxic aluminum

Aluminum toxicity has long been known to damage plant cells and inhibit the growth of plants. Aluminum is widely found in soils that are too acidic, and as human activities have increased soil acidity across the globe, aluminum ...
