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.

The Australian Plant Phenomics Network (APPN, formerly known as APPF) is comprised of nine institutions offering controlled-environment phenotyping facilities, mobile phenotyping units, and field sites strategically spread across Australia’s diverse climate zones.
Results show that the processing of a specific module of Photosystem-associated proteins and concomitantly progression of chloroplast biogenesis depend on active photosynthesis early in plant development.
Global increases in mean minimum temperature (i.e. night temperature) is associated with significant crop yield losses.
Blumeria hordei (Bh) causes the powdery mildew disease of barley. In resistant barley lines, the RNase-like Bh AVRA effectors are recognized by immune receptors encoded at the barley Mildew locus a (Mla).
In this talk I will discuss our progress in understanding the impact of eCO2 concentrations on a forest ecosystem using data from the Free-Air Carbon dioxide Enrichment (FACE) site at the Birmingham Institute for Forest Research (BIFoR), and show some recent data of the effects on the nutritional status of seed.
Plant biotechnology has become an essential tool in the effort to enhance global food security. Faced with challenges such as a growing population, climate change, and land degradation, plant biotechnology plays a crucial role in improving food production, quality, and agricultural sustainability.
