Poplar tree discovery could help shape the future of energy and biomaterials

A University of Missouri-led study has uncovered how poplar trees can naturally adjust a key part of their wood chemistry based on changes in their environment, supporting improved bioenergy production. The discovery sheds light on the role of lignin and its potential to create better biofuels and sustainable products.

Plant guard cells can count environmental stimuli

Plant guard cells use calcium signals to regulate stomatal movement in response to environmental stimuli. By counting up to six consecutive calcium transients, guard cells can close their stomata and conserve water.

Hitting the brakes on the cell cycle for the formation of plant stomata

Researchers discovered that a transcription factor called MUTE induces a cell cycle inhibitor SMR4 to slow down the cell cycle, allowing for asymmetric division. A variant with excess SMR4 showed a longer cell cycle during symmetric division, revealing a crucial regulatory mechanism in plant stomatal development.

Remote control for plants

Researchers at the University of Würzburg have successfully introduced a light-sensitive switch into tobacco plants' guard cells, enabling remote control over stomatal movements. This technology has enormous potential for improving plant drought resistance and water conservation.

Open sesame: Micro RNAs regulate plant pores

Researchers found that micro RNAs, like miR399, play a crucial role in regulating stomatal pore development and density in response to environmental cues. The study could lead to strategies for improving crop productivity by adjusting stomatal pore density.

How plants measure their carbon dioxide uptake

In a balancing act between drying out and starving in dry conditions, plants use an elaborate network of sensors to regulate their carbon dioxide uptake. The study reveals that guard cells have sensors for CO2 and ABA, allowing them to measure photosynthesis and water supply, and adjust the stomata accordingly.

How plants learned to save water

Researchers at Julius-Maximilians-Universität Würzburg reconstructed the evolutionary history of genes controlling leaf pore movement in flowering plants. They found that most genes belong to old families present in all plant groups, including green algae, suggesting they developed before land colonization.

News about a plant hormone

Scientists have found that jasmonic acid triggers the quick closure of stomata, a crucial mechanism for plants to conserve water during drought stress. The discovery also reveals a molecular crosstalk between jasmonic acid and abscisic acid, two key plant hormones involved in regulating stomatal conductance.

Stomata -- the plant pores that give us life -- arise thanks to a gene called MUTE

A University of Washington-led team discovered that the MUTE gene regulates stomatal development in plants, controlling cell division and gas exchange. The study found that MUTE activates genes that promote cell division and repressors that prevent further division, resulting in a tightly coupled sequence of activation and repression.

Why cereal is better

Researchers discovered that two amino acids in the guard cells' protein SLAC1 enable grasses to quickly close their stomata and prevent water loss. This mechanism allows grasses to adapt better to drought, making them more suitable for water-scarce regions.

Discovery of compounds that keep plants fresh

Researchers at Nagoya University have discovered new compounds that can control stomatal movements in plants, preventing leaves from drying up and suppressing withering. These compounds could lead to the development of agrochemicals for drought tolerance and extend the freshness of cut flowers.

Trio of plant genes prevent 'too many mouths'

A trio of plant genes have been found to play a crucial role in regulating the density of microscopic pores called stomata, which are essential for photosynthesis. By understanding how these genes function, scientists can gain insights into how plants evolved to survive on land and how they adapt to changing environmental conditions.

Explaining how ozone "chokes up" plants

Researchers identified how ozone 'chokes up' plants by directly affecting guard cells, inhibiting stomatal opening and reducing photosynthesis. This knowledge may lead to breeding or genetically engineering less ozone-sensitive plant varieties to improve productivity in regions with high ozone exposure.
