The effects of climate change on the physiology of alfalfa

13.04.2006
The biologist Gorka Erice Soreasu, a researcher in the Department of Plant Biology of the University of Navarra, has studied the effects of climate change on the physiology of alfalfa.

This study, which forms part of his doctoral thesis, demonstrates that this plant, frequently used as feed for farm animals, adapts to increases in carbon dioxide (CO2), temperature and dryness, protecting itself in this way from the effects of climate change.

His research, which focused on the regrowth of the plant, reveals that alfalfa grows more with elevated concentrations of carbon dioxide (CO2), in particular when this condition coincides with high temperatures. The effects can be affected by other variables, such as the availability of water in the soil, which would reduce its growth and can modify its response to CO2. In addition, in the study it was confirmed that the process of photosynthesis can be stimulated or reduced by CO2, depending on the growth phase of the plant.

Variability in the responses

As this study highlighted, one of the most interesting aspects of this type of plant is the increase in nutrient storage in the roots, especially of proteins, when the plant is periodically cut back. These nutrient reserves contribute to rapid regrowth and to maintaining the perenniality of this crop. Similarly, it has been shown that a moderately dry climate maintained over time favors the accumulation of these reserve proteins, which can stimulate the growth of the plants during the following regrowth.

The results show the great variability of plant response to increases in CO2. Thus, a greater availability of CO2, which in principle should stimulate growth through increase photosynthesis, when it interacts with other variables such as the temperature or availability of water, can modify significantly the response of the alfalfa, depending on its stage of growth.

Im Focus: Can the immune system be boosted against Staphylococcus aureus by delivery of messenger RNA?

Staphylococcus aureus is a feared pathogen (MRSA, multi-resistant S. aureus) due to frequent resistances against many antibiotics, especially in hospital infections. Researchers at the Paul-Ehrlich-Institut have identified immunological processes that prevent a successful immune response directed against the pathogenic agent. The delivery of bacterial proteins with RNA adjuvant or messenger RNA (mRNA) into immune cells allows the re-direction of the immune response towards an active defense against S. aureus. This could be of significant importance for the development of an effective vaccine. PLOS Pathogens has published these research results online on 25 May 2017.

Staphylococcus aureus (S. aureus) is a bacterium that colonizes by far more than half of the skin and the mucosa of adults, usually without causing infections....

Im Focus: A quantum walk of photons

Physicists from the University of Würzburg are capable of generating identical looking single light particles at the push of a button. Two new studies now demonstrate the potential this method holds.

The quantum computer has fuelled the imagination of scientists for decades: It is based on fundamentally different phenomena than a conventional computer....

Im Focus: Turmoil in sluggish electrons’ existence

An international team of physicists has monitored the scattering behaviour of electrons in a non-conducting material in real-time. Their insights could be beneficial for radiotherapy.

We can refer to electrons in non-conducting materials as ‘sluggish’. Typically, they remain fixed in a location, deep inside an atomic composite. It is hence...

Im Focus: Wafer-thin Magnetic Materials Developed for Future Quantum Technologies

Two-dimensional magnetic structures are regarded as a promising material for new types of data storage, since the magnetic properties of individual molecular building blocks can be investigated and modified. For the first time, researchers have now produced a wafer-thin ferrimagnet, in which molecules with different magnetic centers arrange themselves on a gold surface to form a checkerboard pattern. Scientists at the Swiss Nanoscience Institute at the University of Basel and the Paul Scherrer Institute published their findings in the journal Nature Communications.

Ferrimagnets are composed of two centers which are magnetized at different strengths and point in opposing directions. Two-dimensional, quasi-flat ferrimagnets...
