The 'water-saving' effect of vegetation under rising CO₂ may be overestimated

Climate warming is intensifying terrestrial water scarcity and drought risks worldwide. Meanwhile, rising atmospheric CO2 reduces plant stomatal conductance—the openness of leaf pores that governs both CO2 intake and water loss—and improves water-use efficiency, which has been wi

How bacteria use circadian clocks to colonize their world

Research has revealed how bacteria rely on circadian clocks to control the spread of their multicellular colonies. The findings provide important clues as to how we might improve soil health and plant growth. They may also help explain how some bacteria spread hospital-acquired i

ROS-producing enzymes guide plant cell division and tissue patterning, gene-editing study

Reactive oxygen species (ROS) produced naturally during cellular metabolism often cause oxidative damage to cells. However, these molecules also play an important role in normal cellular signaling. While ROS are established as essential signaling molecules in various organisms, t
