ARC Centre of Excellence in Plant Energy Biology. We propose a novel approach to improve sustainable yield by optimising the overall efficiency of energy capture, conversion and use by plants. Efficiency gains in metabolism, transport, and development will be more effective than optimising single nutrient inputs or product outputs. Improving multiple parameters simultaneously is a necessary solution to the increasing demand for more crop yield from finite land, water, and nutrient resources.

We propose a novel approach to improve sustainable yield by optimising the overall efficiency of energy capture, conversion and use by plants. Efficiency gains in metabolism, transport, and development will be more effective than optimising single nutrient inputs or product outputs. Improving multiple parameters simultaneously is a necessary solution to the increasing demand for more crop yield from finite land, water, and nutrient resources. Unpredictable environmental challenges adversely affect plant growth and further perturb plant energy balance, limiting yield. The epigenetic controls, gene variants and signals discovered will provide a new basis for sustainable productivity of crops and will future-proof plants in changing climates.Read moreRead less
Defining pathways that establish and maintain reproductive cell identity in plant ovules and seeds. Unlike animals, individual somatic cells in plants have the remarkable ability to regenerate into new plants, depending on the signals they perceive. This developmental plasticity is particularly important during normal plant growth, when mature cells adopt new identities within multicellular environments. Tissue complexity is critical for the utilisation of plants in society as food, fuel and fib ....Defining pathways that establish and maintain reproductive cell identity in plant ovules and seeds. Unlike animals, individual somatic cells in plants have the remarkable ability to regenerate into new plants, depending on the signals they perceive. This developmental plasticity is particularly important during normal plant growth, when mature cells adopt new identities within multicellular environments. Tissue complexity is critical for the utilisation of plants in society as food, fuel and fibre, but how and why plant cells adopt or change identity has been difficult to determine. This project aims to employ next-generation molecular methods to identify pathways driving differentiation of specific ovule and seed cell-types, which directly impact crop quality, yield and end-use.Read moreRead less
Molecular switches and genetic consequences of grain retention in cereals. Grain retention at maturity was key for crop domestication and laid the basis for farming. Wheat and barley have evolved a novel mechanism for ensuring grain retention and, although the genes are known, the mechanisms for action are not. Grain dispersal in the wild relatives involves highly targeted changes in the walls of a small number of cells. This project will explore how the two identified genes control this proces ....Molecular switches and genetic consequences of grain retention in cereals. Grain retention at maturity was key for crop domestication and laid the basis for farming. Wheat and barley have evolved a novel mechanism for ensuring grain retention and, although the genes are known, the mechanisms for action are not. Grain dispersal in the wild relatives involves highly targeted changes in the walls of a small number of cells. This project will explore how the two identified genes control this process and clarify their mode of action. The genes ensuring grain retention have been so critical for domestication that the region surrounding them has become genetically fixed. The project will assess the implication of fixation on genetic diversity and develop options to bring novel variation into breeding programs.Read moreRead less

Summary
Harnessing Mendel’s workhorse: meiotic crossovers for genetic diversity in crop breeding. Introducing genetic diversity from wild species into elite lines of wheat and barley may increase their resistance to the stresses they are exposed to in the field. Modern breeding cultivars could capture up to ten times more genetic variation. This project aims to gain fundamental insights into the genetic and environmental factors that limit the rates at which new genomic combinations can be made.

Modern breeding cultivars could capture up to ten times more genetic variation. This project aims to gain fundamental insights into the genetic and environmental factors that limit the rates at which new genomic combinations can be made. This will transform wheat and barley breeding methods, unlocking available genetic diversity to produce new varieties. Read moreRead less

Summary
Delivering breeding-oriented genetic tools for cereal disease resistance. This project will focus specifically on delivering the genetic tools to the industry partner to assist its wheat and barley breeders to increase the accuracy and efficiency of incorporating the durable wheat stripe rust disease and barley leaf rust disease resistance into their core germplasm collections, respectively. The expected outcomes will also contribute to filling our knowledge gap in understanding the cereal rust ....Delivering breeding-oriented genetic tools for cereal disease resistance. This project will focus specifically on delivering the genetic tools to the industry partner to assist its wheat and barley breeders to increase the accuracy and efficiency of incorporating the durable wheat stripe rust disease and barley leaf rust disease resistance into their core germplasm collections, respectively. The expected outcomes will also contribute to filling our knowledge gap in understanding the cereal rust innate immune system and benefit other cereal fungal pathosystems. The wide application of the expected outcomes from the proposed project will reduce the utilisation of fungicides and subsequently will subsequently contribute to the resilience of cereal crops and sustainable global food security.Read moreRead less
