How do plants make organelles?

Currently the worlds crop productivity is stagnating while the population is increasing. How we address this looming agricultural crisis will be one of the greatest scientific challenges. It has been suggested that enhancing the energy efficiency of plants by optimizing energy capture, conversion and use in changing environments could improve the sustainable productivity of plants. Central to plant energy efficiency are the chloroplasts and mitochondria the main energy producers of plants. Mitochondria and chloroplasts are essential for plant growth and development. They not only provide energy and carbon sources for cells, but have evolved to play vital roles in amino acid metabolism, hormone biosynthesis and cellular signalling. Even though they arose from different endosymbiotic origins mitochondria and chloroplasts contain many similarities, including containing small genomes, which rely on nuclear encoded factors for maintenance and expression. The nuclear encoded genes involved in photosynthesis and oxidative phosphorylation are crucial for plant growth, and the crosstalk between the nucleus and the organelles is essential for proper cell functioning. In this talk our recent data on how plants make mitochondria and the role of chloroplasts in male sterility with be discussed. Followed by our planned projects for the future.
