Scientists at the Australian Research Council (ARC) ARC Centre of Excellence for Translational Photosynthesis (CoETP) have found that some plants have ten times more communication channels inside their leaves than other plants, which they think is a crucial factor in determining photosynthetic efficiency.
ANU congratulates distinguished scientist and ANU Professor Graham Farquhar AO for being named the 2018 Senior Australian of the Year.
Photosynthesis is an essential biological process that depends on the activity of the enzyme Rubisco which catalyses carbon fixation. Rubisco is slow, inefficient and cannot accurately distinguish between CO2 and O2. ANU researchers have been trying to improve the efficiency of Rubisco in crop plants.
The investigations into carbon fixation and gas exchange by RSBS researchers were essential to the understanding of photosynthesis, and the development of new processes to increase the efficiency of the photosynthetic process in agriculture.
Carboxysomes are polyhedral protein micro-compartments in cyanobacteria which concentrate CO2 and increase the efficiency of carbon fixation. In 1993, RSBS researchers Dean Price, Murray Badger and Susan Howitt determined the genetic sequence encoding for the proteins that form the protein shell of a carboxysome.
Legumes are an interesting plant to study due to their symbiotic relationship with nitrogen fixing bacteria called Rhizobia, which are housed within specialised root structures called nodules. The work of ANU researchers has been very important for our understanding of symbiosis, nodule formation and nitrogen fixation.

‘Translational research’ became an increasingly common term when it was realised that much agriculturally inspired basic research failed to contribute to the improvement of crops.
The steady-state mRNA abundance is an outcome of transcript synthesis counter-balanced by turnover.
Slow wave potentials propagate from sites of damage to distal leaves in wounded plants.
Plant biotechnology predominantly relies on a restricted set of genetic parts with limited capability to customize spatiotemporal and conditional expression patterns.
As sessile organisms, plants have evolved a multitude of mechanisms to acclimate to their environment enabling the plant to optimise development and reproduction, and fight off or resist both biotic and abiotic stresses they may encounter through their life cycle.
