Plant survival under three simultaneous stressors may hinge on a single protein

Researchers at the University of Missouri have discovered certain proteins may be the key to saving plants' lives when multiple stressors hit at the same time. This knowledge may one day lead to crops that are more resistant to harsh conditions brought on by multiple stressors during the same growing seasons.

What's in your salad? Crops exposed to nanoplastics may boost heavy metal intake

Research from Texas A&M University shows that lettuce plants exposed to nanoplastics and cadmium, a toxic heavy metal, absorb up to 61% more cadmium into their edible leaves than plants exposed to cadmium alone.

United we stand: Plants that physically touch each other are more resilient to excess light stress

New research has found when plant leaves physically touch each other, they seem to form a biological signalling network to warn each other about the upcoming stress. This can boost their resilience to withstand intense light, which is a common environmental challenge.

Temperature shifts change plant proteins that power photosynthesis

Humans adjust to changes in temperature by putting on a sweater or taking off layers. Plants adjust to temperature changes, in part, by switching the way they express the protein that performs the critical first step of photosynthesis,

How do thirsty plants hold out during drought?

Salk Institute scientists create high-resolution atlas showing how droughts affect plant cells and identify a gene that could be targeted to create more resilient crops.

Найден способ надежно обезвредить тяжелые металлы в почве при помощи супер-биоугля

Pot experiments in both unpolluted and metal-contaminated soil revealed that BC@MIL facilitated the transformation of Cu, Pb, Zn, and Cd from acid exchangeable fraction to oxidizable and residual fractions. The risk assessment code decreased, and the reduced partition index increased for all heavy metals with sorbent application, indicating an increase in their fixation strength in soils.

Integrated physiological and transcriptomic analysis revealed key genes and pathways related to continuous drought and salinity stress in Populus

Integrated physiological and time-series transcriptomic analyses in poplar demonstrate drought prioritizes cell wall remodeling, while salt stress immediately activates ion transporters and JA signaling, defining distinct molecular adaptation mechanisms.

Giant virus DNA may help polar algae survive harsh environments

In the game of survival, you can't always go it alone. Tiny algae living in the harsh conditions of the world's polar oceans appear to be better able to withstand the cold, high salinity, and extreme UV radiation, thanks in part to giant virus DNA in their genome, according to a study published in Current Biology.

Tea under nitrogen stress rewires flavor and defense

A research team has uncovered how fresh shoots of Camellia sinensis ‘Lingtou Dancong’ respond to nitrogen deficiency by extensively reprogramming their metabolism and gene activity.

Understanding cell structures: Novel tool enables analysis of the plant actin cytoskeleton

In experimental tests, including studies on the model plant Arabidopsis thaliana, the researchers were able to accurately map and analyze complex filament networks using GraFT. The tool proved its worth not only in the investigation of cell structures under various physiological conditions, but also in modeling dynamic changes within the cytoskeleton. GraFT provides valuable insights into plant cell biology. With the tool's assistance, the researchers were able to observe how certain virulence factors, which enable tissue damage, alter the properties of the actin cytoskeleton—findings that are crucial for understanding plant pathogen defense.

How an internal plant 'thermostat' guides root growth in unpredictable temperatures

Plants can't move to escape the heat like humans can; they are forced to adapt. As temperatures fluctuate, one key survival strategy is the ability of roots to keep growing, allowing plants to access water and nutrients farther.

When trees get 'sunburn': Study shows how young trees can handle the heat

Can our forests adapt to a hotter and drier future climate? Temperatures are predicted to rise up to 5°C. Forest management needs to adapt to these conditions, which requires a better understanding.

Plants use a protein-tagging complex to control stress survival

A specific cellular mechanism regulates the protein balance of plants, thereby influencing how they respond to environmental stress.
