Unique lab seeks drought-tolerant traits in cotton, other plants

27.06.2011
As billion-dollar agricultural losses continue to mount in the withering Texas heat, Texas AgriLife Research scientists in Corpus Christi are taking a closer look at why some cotton varieties do better than others in drought conditions.

"We want to better understand those traits that control water use in plants so we can transfer that information to breeders and geneticists to more quickly develop drought-tolerant cultivars so badly needed here," said Dr. Carlos Fernandez, a plant physiologist at the Texas AgriLife Research and Extension Center in Corpus Christi. Dr. Carlos Fernandez checks leaves of a cotton plant being evaluated for its drought tolerance.

Dr. Carlos Fernandez checks leaves of a cotton plant being evaluated for its drought tolerance.

To coax that information from nature, Fernandez designed and constructed a unique drought-tolerance greenhouse laboratory last year that is fully automated and computerized. The system closely tracks the water use and growth of various cotton varieties from planting to harvest, he said.

"All plants are treated equally," Fernandez said. "They all have the exact same amount of high-absorbent soil to remove that as a variation factor. Each also gets exactly the same amount of nutrient solution. We irrigate them daily up to a point when we stop or reduce irrigation to see how the plant reacts to the water deficiency."

Fernandez then precisely measures each plant's leaf area, stomatal density, water-conducting vessels, rooting systems and other characteristics. "We do this not only to look at the effects on water use and growth, but also the production of fiber and fiber quality."

The information and conclusions he develops are then shared with breeders and geneticists who may be able to provide growers with drought-tolerant cotton varieties.

"The idea is to tell them, 'Look at these plant traits that seem to confer a particular water economy in this cultivar. Look at this trait because in this cultivar it gives us this result.'"

Research using his greenhouse laboratory, which measures some 50 feet by 60 feet, is not limited to cotton, Fernandez said.

"This system can be used for other crops, but we're starting with cotton for obvious reasons, since it is such a large part of our agricultural production, and because water limitation is the most important yield-limiting factor here," he said.

The cooperative work of physiologists, geneticists and breeders on a single issue is something that hasn't been done in the past, Fernandez said.

"We are trying to generate the synergy of different disciplines working together to more quickly develop cultivars that will better tolerate the heat and water stresses that seem to be so prevalent lately."

Fernandez's AgriLife Research colleagues include Drs. Jane Dever and Steve Hague, cotton breeders in Lubbock and College Station, respectively.

Im Focus: Climate satellite: Tracking methane with robust laser technology

Heatwaves in the Arctic, longer periods of vegetation in Europe, severe floods in West Africa – starting in 2021, scientists want to explore the emissions of the greenhouse gas methane with the German-French satellite MERLIN. This is made possible by a new robust laser system of the Fraunhofer Institute for Laser Technology ILT in Aachen, which achieves unprecedented measurement accuracy.

Methane is primarily the result of the decomposition of organic matter. The gas has a 25 times greater warming potential than carbon dioxide, but is not as...

Im Focus: How protons move through a fuel cell

Hydrogen is regarded as the energy source of the future: It is produced with solar power and can be used to generate heat and electricity in fuel cells. Empa researchers have now succeeded in decoding the movement of hydrogen ions in crystals – a key step towards more efficient energy conversion in the hydrogen industry of tomorrow.

As charge carriers, electrons and ions play the leading role in electrochemical energy storage devices and converters such as batteries and fuel cells. Proton...

Im Focus: A unique data centre for cosmological simulations

Scientists from the Excellence Cluster Universe at the Ludwig-Maximilians-Universität Munich have establised "Cosmowebportal", a unique data centre for cosmological simulations located at the Leibniz Supercomputing Centre (LRZ) of the Bavarian Academy of Sciences. The complete results of a series of large hydrodynamical cosmological simulations are available, with data volumes typically exceeding several hundred terabytes. Scientists worldwide can interactively explore these complex simulations via a web interface and directly access the results.

With current telescopes, scientists can observe our Universe’s galaxies and galaxy clusters and their distribution along an invisible cosmic web. From the...

Im Focus: Optoelectronic Inline Measurement – Accurate to the Nanometer

Germany counts high-precision manufacturing processes among its advantages as a location. It’s not just the aerospace and automotive industries that require almost waste-free, high-precision manufacturing to provide an efficient way of testing the shape and orientation tolerances of products. Since current inline measurement technology not yet provides the required accuracy, the Fraunhofer Institute for Laser Technology ILT is collaborating with four renowned industry partners in the INSPIRE project to develop inline sensors with a new accuracy class. Funded by the German Federal Ministry of Education and Research (BMBF), the project is scheduled to run until the end of 2019.
