Legume Lessons: Reducing Fertilizer Use Through Beneficial Microbe Reactions

11.05.2012
Janine Sherrier, professor in the Department of Plant and Soil Sciences at the University of Delaware, is part of a team that has been awarded $6.8 million from the National Science Foundation (NSF) to study the legume Medicago truncatula.

Sherrier leads one of four research groups participating in this project, which represents a collaborative effort between researchers at the Noble Foundation, the Boyce Thompson Institute at Cornell University, the University of Delaware, and the University of North Texas.

“The aim of this large project is to generate resources for the U.S. and international research communities. We will generate resources to help accelerate the transfer of fundamental laboratory research results into useful applications for crop production,” said Sherrier.

In past years, the NSF has supported projects to sequence the complete genomes of organisms, including M. truncatula. The resources generated by this new NSF grant will help researchers define the roles of all of the individual genes within the genome and to elucidate how they are important for legume growth.

“Legumes, such as beans and lentils, provide one third of the protein consumed as part of the human diet globally. Legumes also contribute fiber and micronutrients to the human diet and are utilized widely as forage crops for livestock,” said Sherrier.

M. truncatula has been selected as a research model to study the symbiotic relationships that are characteristic of legumes. Unlike many species of plants, legumes rely on interactions with rhizobia (naturally-occurring beneficial microbes) to supply them with nitrogen. Many crop plants are supplemented with industrially produced nitrogen fertilizer, and the synthesis of the fertilizer is an energy-intensive process.

“As much as four percent of the world’s natural gas is consumed in the production of nitrogen fertilizers, releasing carbon dioxide by-products into the atmosphere,” said Sherrier.

When nitrogen is not present at sufficient levels in the soil to support plant growth, legumes create a home for beneficial bacteria in their roots. The plant develops a novel root organ where bacteria can grow, multiply and enter the plant cell, and within the plant cells the bacteria convert atmospheric nitrogen into a fertilizer for the plant. This greatly reduces the amount of fertilizer and energy necessary to produce a successful crop, lowers production costs for farmers and reduces runoff of fertilizers into the groundwater.

The focus of Sherrier’s research program is on the protein-to-protein interactions that are necessary for such beneficial plant-bacteria relationships to occur.

“If the plant lacks a specific protein, then this can allow bacteria to enter the plant and simply take the sugar without producing anything in return. This would be detrimental for a crop,” she explained.

As part of the NSF-funded project, Sherrier’s team will also be developing and teaching a 4-H summer camp across Delaware to teach children about how different microbes are important for agriculture. Campers will participate in science-based activities, such as using microscopes and making yogurt. The camps will contribute to the development of future growers in all three counties.

Im Focus: AchemAsia 2019 will take place in Shanghai

Moving into its fourth decade, AchemAsia is setting out for new horizons: The International Expo and Innovation Forum for Sustainable Chemical Production will take place from 21-23 May 2019 in Shanghai, China. With an updated event profile, the eleventh edition focusses on topics that are especially relevant for the Chinese process industry, putting a strong emphasis on sustainability and innovation.

Founded in 1989 as a spin-off of ACHEMA to cater to the needs of China’s then developing industry, AchemAsia has since grown into a platform where the latest...

Im Focus: First real-time test of Li-Fi utilization for the industrial Internet of Things

The BMBF-funded OWICELLS project was successfully completed with a final presentation at the BMW plant in Munich. The presentation demonstrated a Li-Fi communication with a mobile robot, while the robot carried out usual production processes (welding, moving and testing parts) in a 5x5m² production cell. The robust, optical wireless transmission is based on spatial diversity; in other words, data is sent and received simultaneously by several LEDs and several photodiodes. The system can transmit data at more than 100 Mbit/s and five milliseconds latency.

Modern production technologies in the automobile industry must become more flexible in order to fulfil individual customer requirements.

Im Focus: Sharp images with flexible fibers

An international team of scientists has discovered a new way to transfer image information through multimodal fibers with almost no distortion - even if the fiber is bent. The results of the study, to which scientist from the Leibniz-Institute of Photonic Technology Jena (Leibniz IPHT) contributed, were published on 6thJune in the highly-cited journal Physical Review Letters.

Endoscopes allow doctors to see into a patient’s body like through a keyhole. Typically, the images are transmitted via a bundle of several hundreds of optical...

Im Focus: Water is not the same as water

Water molecules exist in two different forms with almost identical physical properties. For the first time, researchers have succeeded in separating the two forms to show that they can exhibit different chemical reactivities. These results were reported by researchers from the University of Basel and their colleagues in Hamburg in the scientific journal Nature Communications.

From a chemical perspective, water is a molecule in which a single oxygen atom is linked to two hydrogen atoms. It is less well known that water exists in two...
