A/Prof Tucker is a plant scientist with research expertise in plant reproduction, seed development and cell wall biosynthesis. He received his PhD from the University of Adelaide and CSIRO Plant Industry in 2003, undertook postdoctoral research as an EMBO long-term fellow at the University of Freiburg in Germany and in 2011 joined the ARC Centre of Excellence in Plant Cell Walls as a Senior Research Fellow. In 2015 he was awarded an ARC Future Fellowship and in 2017 was promoted to Associate Professor.
Research in his laboratory investigates how distinct plant cells and tissues are produced, with the aim of understanding how they can be engineered to optimise plant growth, yield and end-use. Current projects are focused on the characterisation of key pre- and post-fertilisation stages in the cereal monocot barley (Hordeum vulgare) that influence grain quality and yield.
His work has been published in journals including Developmental Cell, PloS Genetics, Plant Cell and Development.

Cereal grains are an important dietary component that contribute benefits for human health and nutrition, and can also be utilised for industrial processes in the brewing, fibre and food industries. Within the cereal grain, different tissues such as the outer aleurone layer and inner starchy endosperm accumulate varying amounts of starch, dietary fibre and antioxidants. Genes controlling the balance between outer and inner identity might therefore be used to tailor the composition of cereal grains for specific end uses. We have been studying endosperm development in cereal species to understand the genetic basis for endosperm cell identity, with a specific focus on mechanisms that allow different cell types to communicate. This work is supported by the ARC and GRDC (https://grdc.com.au/) and involves international partners including the James Hutton Institute (http://www.hutton.ac.uk/staff/robbie-waugh). We also enjoy share a strong partnership with the State Breeding Institute at the University of Hohenheim (https://www.uni-hohenheim.de/institution/landessaatzuchtanstalt-2) relating to genetic analysis of complex traits in cereals.

Plant reproduction delivers many fruits, grains, beverages and industrial products that are a fundamental requirement of human society. Understanding how plants produce their gametes is therefore a key area of interest to ensure stable and improved yields in the future. We have been studying ovule development in Arabidopsis, barley and Hieracium to establish how female reproductive cells are specified. Communication between different ovule cells based on their position has long been hypothesised as a mechanism controlling reproductive cell identity, but is challenging to address due to the technical difficulties in accessing them in the ovule. With partners at CSIRO Agriculture (Dr Anna Koltunow), we have developed and utilised a method for Laser Assisted Microdissection (LAM) to capture these cells and characterise genes involved in ovule development. In parallel, large scale genetic screens have led to the identification of novel markers of reproductive cell development and the delineation of molecular pathways influencing reproductive cell fate. Work in this area is supported by the ARC (http://www.arc.gov.au/), as well as international partnerships with the SEXSEED consortium (http://www.fc.up.pt/sexseed/), North Carolina State University (http://www4.ncsu.edu/~rgfranks/) and the University of Freiburg (http://www.biologie.uni-freiburg.de/LauxLab/default%20tafang.htm)

Plant Cell Walls
Plant cells are surrounded by a complex wall consisting of polysaccharides, proteins, phenolic acids and water. The cell wall fulfils a crucial role in supporting plant growth and development and defending against pathogen invasion. In collaboration with the ARC Centre of Excellence in Plant Cell Walls (http://www.plantcellwalls.org.au/) we have been studying how different components of the wall are synthesised, how they influence reproductive development. We also collaborate with Prof Diane Mather (https://researchers.adelaide.edu.au/profile/diane.mather) to determine how cell walls interact with barley parasites such as the cereal cyst nematode, Heterodera avenae.

Shoot Meristem Development
ARGONAUTE proteins bind small RNA molecules to silence the transcription and translation of homologous target sequences. In Arabidopsis, several AGOs contribute to development of the embryonic shoot meristem. Using a combination of genetic screens and natural mutants, we are studying the broader network of AGO-dependent genes controlling embryonic meristem development to determine how these might be tailored to improve plant growth under adverse conditions.
