Scientists from the ANU Research School of Biology made a major breakthrough for world food security while investigating photosynthesis. They discovered that chloroplasts — which convert sunlight into sugars through photosynthesis — can also activate a chemical signal to close stomata on leaves to protect individual plants from losing vital water in drought. By boosting this chloroplast signal in barley plants, the team improved drought survival time by around 50%. The team is exploring ways to boost this chloroplast signal in different crops, through breeding, genetic or agronomic strategies.
Connecting with industry
More than five million hectares of agricultural land in Australia is hydrophobic, meaning the soil repels water. Global chemical company BASF co-funded research by scientists at Swinburne University, led by chemistry Professor David Mainwaring, with the CRC for Polymers, to develop solutions to help soil accept water. These new soil-wetting agents have increased crop yields. The multidisciplinary team has now patented two polymer surfactants and a soil diagnostic test.
Murdoch University’s Centre for Sustainable Aquatic Ecosystems is tackling clean-energy and fresh-water challenges with a cross-disciplinary approach. Researchers in aquatic biology and ecology, marine mammal ecology, fisheries, aquaculture, algal biotechnology, oceanography, human-use and habitat assessments, bioinformatics, economics and spatial sciences are all working together. One recent project tackled challenges around the release of aquaculture-bred fish into the wild environment.
Creating real value
Inspired by plant experiments on the International Space Station, University of Queensland researchers are advancing the technology of ordinary glasshouses with a revolutionary “speed breeding” technique that can cut plant breeding time in half. Dr Lee Hickey and his team developed a ‘desktop breeding cabinet’ that will allow researchers to develop wheat, barley, canola and other crops adapted to drought, changed local soil and climate conditions.
