Photosynthesis and plant energy biology
About
The capture of CO2 by photosynthesis using sunlight is fundamental to the maintenance of life on earth. At the Research School of Biology, we study the energy metabolism of plants, algae and cyanobacteria, including the functioning of light capture, CO2 fixation and the interactions with respiration processes and how these determine growth and productivity of agricultural and natural ecosystems.
Our approaches range from synthetic biology to physiology and plant phenomics. The ANU node of the Australian Plant Phenomics Facility is developing new modeling and machine learning approaches to enables us to scale from leaf to field. This means we can translate our knowledge about the biochemistry and physiology of leaves and individual plants to their functioning in agroecosystems, in particular under changing climatic conditions.
Our research is embedded in the ARC Centre of Excellence for Translational Photosynthesis, the ARC Centre of Excellence in Plant Energy Biology, as well as the Bill and Melinda Gates-funded C4 Rice and RIPE (Realizing Increased Photosynthetic Efficiency) projects.
Groups
Atkin Group studies plant metabolic responses to environmental gradients, including how leaf respiration varies within and among biomes across the globe.
The Badger Group is focused on understanding the ways different photosynthetic organisms have adapted to efficiently fix CO2, where CO2 is a limiting substrate.
We study the genetic basis of Climate Adaptation in foundation plant species, using state of the art Genomic and Phenomic techniques
We work on engineering strategies to increase crop tolerance to salinity and drought, and to advance water filtration technology.
We aim to unravel molecular and biochemical mechanisms that enable plant cells to adapt to challenging environmental conditions
We investigate the structural organization of the thylakoid membrane; electron flow in leaves; quantification of Photosystem II; and photodamage.
Our group studies plasmodesmata to answer important plant science questions related to development, cellular transport, root biology, signalling and evolution.
We study relating photosynthesis to nitrogen; CO2 diffusion within leaves; analysing how plants acclimate to their light environment.
Our research includes: photosynthesis and growth with N2 and water use of plants; stomatal physiology; isotopic composition of plants & global change science.
Our research focuses on the identification of enhanced photosynthetic properties in crop and model plant germplasm, and improving C4 photosynthesis.
The Masle group's central interest is on the interplay between genetic and environmental determinants of plant development and adaptation to stress.
The Melonek Group studies the genetic and molecular basis of cytoplasmic male sterility and fertility restoration in plants.
The overarching theme of our research is to determine the controls and regulators of communication between the chloroplast and nucleus.
The Price lab is presently focusing on the molecular biology and physiology of photosynthesis in cyanobacteria (blue-green photosynthetic bacteria) and plants
We are investigating aspects of carbon acquisition by plants including the biochemistry of CO2 fixation and regulation of CO2 diffusion into and within leaves.
We focus on the development and use of synthetic tools to scrutinize the biology of the most abundant protein, the photosynthetic CO2-fixing enzyme Rubisco.

One of the illustrious founder members of RSBS passed away on 11 April 2021. Jeremy David Pickett-Heaps FAA, FRS worked in the (then) Department of Developmental Biology from 1968-70. His surveys of ultrastructural aspects of cell division in green algae (many collected from Lake Burley Griffin and Sullivan’s Creek) led him to a new formulation of the evolution of the Plant Kingdom, a landmark contribution in the plant sciences, now confirmed and fleshed out by sequencing data.
ANU experts have found a way to precisely measure a crop’s water loss through its skin, not just the pores on their leaves.
Three researchers from ANU who've changed the way we see the world have been recognised for their ground-breaking work with prestigious awards from The Australian Academy of Science.
Increasing food production is one of the greatest challenges of the 21st century. The Australian Academy of Science has produced a video featuring researchers who are from the ARC Centre of Excellence for Translational Photosynthesis and the ANU Research School of Biology.
Research led by scientists at The Australian National University (ANU) could lead to major improvements in crop production.
Research that could transform global rice production by increasing yields from the world’s number one food crop has been boosted by five more years of funding.
