Worldwide, plants emit about 100 million tons of monoterpenes into the atmosphere each year. These volatile organic molecules include many fragrances such as the molecule pinene—known for its pine fresh scent. Since these molecules are highly reactive and can form tiny aerosol particles that can grow into nuclei for clouds droplets. Natural emissions play an important role in our climate. Therefore, it is important…

Drought stress can interrupt the metabolic and physiological processes of plants, including nitrogen and amino acid metabolism. Researchers in the Department of Plant Biology at Rutgers University took a closer look at the role of amino acids and nitrogen on cool-season turfgrass regrowth or recovery from drought stress.

Prolonged drought has a significant impact on the extent to which rainforest soils can emit and consume biogenic volatile organic compounds (VOCs). This was the finding of an international research team, including scientists from University of Freiburg and Max Planck Institute for Chemistry in Mainz, Germany, who studied the effects of drought and rewetting on soil VOC fluxes.

Abstract. Water scarcity is a serious agricultural problem causing significant losses to crop yield and product quality. The development of technologies to miti

Due to the lack of clear tree-ring boundaries of most of tree species in tropical regions, investigations of tree growth and climate responses using traditional dendrochronological techniques are challenging.

Researchers have discovered a new gene in barley and wheat that controls the angle of root growth in soil, opening the door to new cereal varieties with deeper roots that are less susceptible to drought and nutrient stress, thus mitigating the effects of climate change.

The importance of fog in forest ecosystems has been recognized and debated for centuries. However, the extent to which the leaves of rubber plants can maintain net CO2 assimilation in the fog season is not known.

Recent findings that plants employ a drought-survival mechanism to also defend against nutrient-sucking pests could inform future crop breeding programs aimed at achieving better broadscale pest control.

With over 4 feet of annual precipitation in the Northeast United States, drought is not often considered a major factor affecting the region's forests. But warming temperatures cause forests to dry out quicker between rains. Seedlings are especially vulnerable because their nascent root systems can't access moisture deeper in the soil, according to a University of Maine-led study.

Paeonia ostii is a widely grown woody crop with up to 40% α-linolenic acid in its seed oil, which is beneficial to human health. Drought is a major environmental factor limiting the popularization of P. ostii in hilly and mountainous areas, which may affect plant growth or lead to plant death.

More and more trees are suffering the consequences of decades of manmade climate change. The growth of the European beech has so far suffered decline mainly in southern Europe. European beech is Germany's most important native forest tree species, and it is most commonly found in central Europe.

Microbes are doing a lot under the soil surface that can't be seen with the naked eye—from sequestering carbon to building the foundation of Earth's crust. But even tiny microbes are feeling the stress of a hotter, drier future.

In the research, biologists at Tel Aviv University recorded ultrasonic sounds emitted by tomato and tobacco plants inside an acoustic chamber, and in a greenhouse, while monitoring the plant's physiological parameters.

The world's first covalent organic framework sensors can detect pH changes in living plants, which can provide early warning of drought stress in plants up to 48 hours before traditional methods.

When a plant community is exposed to drought, the different species undergo evolutionary changes. An international study with UZH participation now shows that this leads to improved resilience to future drought stress over time.

Drought can stress trees to death, but heat's effects are less known. New research could hold the keys to protecting conifer forests.

Low water levels in Lake Mead and Lake Powell could stress the power grid, but that's only part of the drought power problem.

MIT researchers César Terrer and Wenzhe Jiao are leveraging a new generation of remote sensing devices to provide high-resolution plant water stress data at regional to global scales.
