Boosting C4 photosynthesis to climate proof crop yields. Building next generation C4 crops, such as maize, sugarcane and sorghum, to cope with drought and heat stress is requisite to ensure the supply of food and fodder. Here we will increase the content and / or catalytic efficiency of the primary carboxylase of C4 photosynthesis (PEPC) that supplies CO2 to the carbon concentrating mechanism and ensures high photosynthetic rates. We will develop new SynBio tools to create and test novel PEPC is ....Boosting C4 photosynthesis to climate proof crop yields. Building next generation C4 crops, such as maize, sugarcane and sorghum, to cope with drought and heat stress is requisite to ensure the supply of food and fodder. Here we will increase the content and / or catalytic efficiency of the primary carboxylase of C4 photosynthesis (PEPC) that supplies CO2 to the carbon concentrating mechanism and ensures high photosynthetic rates. We will develop new SynBio tools to create and test novel PEPC isoforms with desirable properties. Ultimately, the project aims to identify isoforms that improve plant fitness under stress conditions. Optimising PEPC activity will provide next generation solutions to improve water balance and carbon assimilation to keep C4 crops productive under future climates.Read moreRead less
Improving grain legume seeds for future climates. Grain legumes are essential for sustainable agriculture and human dietary protein, but seed quality is predicted to decline under future scenarios of high CO2 and warmer temperatures. This project aims to improve legume seed quality under future climates by comparing metabolites and physiological traits of chickpea and other legumes to establish mechanisms by which legumes maximise seed nutrient allocation. The anticipated outcomes include new me ....Improving grain legume seeds for future climates. Grain legumes are essential for sustainable agriculture and human dietary protein, but seed quality is predicted to decline under future scenarios of high CO2 and warmer temperatures. This project aims to improve legume seed quality under future climates by comparing metabolites and physiological traits of chickpea and other legumes to establish mechanisms by which legumes maximise seed nutrient allocation. The anticipated outcomes include new metabolite-based breeding markers for the improvement of crops with higher seed proteins, micronutrients and bioactive compounds that are adapted to future climates. Seed nutrient improvement will also include increased biological nitrogen fixation to reduce the need for chemical nitrogen fertilisers.Read moreRead less
