The 2nd A. E. V. Richardson Lecture – Podcast Avaliable

Dissecting nitrogen use efficiency in modern wheat, or who cares about nitrogen, and what can we do about it? Listen to Dr Malcolm Hawkesford’s talk which was given for the Inaugural AEV Richardson Lecture held on the 29th November, 2010.

In this Lecture, Dr Hawkesford will discuss targets for crop improvement including nutrient capture, photosynthetic capacity and canopy longevity, nutrient remobilization, yield and quality stability and the grain yield – grain protein conundrum and the prospects for improving grain protein deviation. The basic approach taken during his research involves the field scale screening of a wide diversity of wheat germplasm under different nutritional conditions, as well as exploiting the world’s oldest plant nutrition experiment, the Broadbalk experiment at Rothamsted. Such materials are used for de-convoluting traits contributing to nutrient use efficiency and crop performance, and utilising this variation for novel gene discovery approach via transcriptome and/or QTL analysis. Validation of candidate genes is undertaken via transgenic approaches.

The Harold Woolhouse Lecture 2010 – Podcast Avaliable

“Looking back and looking forward: time for fresh thinking on roles of arbuscular mycorrhizal (AM) fungi in plant phosphorus (P) uptake” Listen to Professor Sally Smith’s talk which was given at the Inaugural Harold Woolhouse Lecture on the 8th November, 2010.

This talk will start with some brief reflections on Harold Woolhouse at the Waite. Professor Smith will then 1) review the immediate relevance of studies of phosphorus (P) nutrition of plants, in the light of the low availability of P in soil, the need for P fertiliser application to achieve satisfactory crop yields and the limited global P resources; 2) introduce arbuscular mycorrhizas as the most common and widespread adaptation involved in plant P uptake; 3) provide an update on how recent research has fundamentally changed knowledge of how AM symbioses influence plant P uptake; and 4) present a new hypothesis to explain why some plants (including the important crops wheat, barley and tomato) sometimes grow better when non-mycorrhizal.

Looking back and looking forward: time for fresh thinking on roles of arbuscular mycorrhizal (AM) fungi in plant phosphorus (P) uptake

This talk will start with some brief reflections on Harold Woolhouse at the Waite.

The 3rd Harold Woolhouse Lecture is named in honour of the former Director of the Waite Agricultural Research Institute. Professor Woolhouse finished his PhD at the University of Adelaide before spending much of his early career (during the 1960s and 1970s) researching heavy metals and senescence. Between 1980 and 1989, Professor Woolhouse developed and directed the world class plant biology research facility, the John Innes Centre (JIC) in Norwich, United Kingdom. In 1990, he became Director of the Waite Agricultural Research Institute and was responsible for the co-location of the South Australian Research and Development Institute and Primary Industries and Resources South Australia on the Waite Campus. He also masterminded the merging of Roseworthy Agricultural College with the University of Adelaide. He left Adelaide in August 1995 due to ill health and passed away in June 1996.

The Inaugural Innovation in Food Lecture – Podcast and Slidecast Avaliable

“Are ‘refined’ carbohydrates worse than saturated fat?” listen to Professor Jennie Brand-Miller’s talk which was given at the Inaugural Innovation Of Food Lecture on the 6th September, 2010, or you can watch the Slidecast below.

This lecture focuses on well-designed studies demonstrating that carbohydrates that are slowly digested and absorbed (i.e. low GI carbs) are good for health and reduce risk factors associated with lifestyle-related diseases such as diabetes. Improving carbohydrate quality is therefore a better approach to health and sustainability issues than ‘ditching the carbs’. Professor Jennie Brand-Miller is recognised for her work on carbohydrates and diabetes. Her books under the series title The New Glucose Revolution have sold over 3.5 million copies worldwide and appeared in 12 languages.

The Inaugural Innovation in Food Lecture

Prof Jennie Brand-Miller
Are ‘refined’ carbohydrates worse than saturated fat?

The inaugural Innovation in Food Lecture was established to recognise individuals making significant research advances in the areas of food, health and nutrition. The Lecture was named for the world class FOODplus Research Centre which is a joint venture between the Functional Food group at the University of Adelaide’s Waite Campus and the Child Nutrition Research Centre at the Women’s and Children’s Health Research Institute. FOODplus is undertaking research linking sustainable agriculture, food and nutrition to improve human health. This research fosters economic relationships with industry and coal-face agriculture, creates research sustainability and translates nutrition research into food products with real health outcomes.

The take home message from health authorities for the past three decades has been ‘eat less fat, especially saturated fat’. Now a new paradigm is arising: that the processed carbohydrates which replaced the energy from fat, may increase the risk of obesity, diabetes and heart disease more so than fat – a finding that has enormous implications for the Australian food and agricultural industry. Both quantity and quality of carbohydrate are relevant to the debate. The rate of digestion and absorption of carbohydrates is assessed as their ‘glycemic index’ (GI). This lecture will focus on well-designed studies demonstrating that carbohydrates that are slowly digested and absorbed (i.e. low GI carbs) are good for health and reduce risk factors associated with lifestyle-related diseases such as diabetes. Improving carbohydrate quality is therefore a better approach to health and sustainability issues than ‘ditching the carbs’. Professor Jennie Brand-Miller is recognised for her work on carbohydrates and diabetes. Her books under the series title The New Glucose Revolution have sold over 3.5 million copies worldwide and appeared in 12 languages.

Bob Symons Lecture

Professor Dieter SollThe inaugural Bob Symons Lecture was given by Professor Dieter Soll on the evolution of the genetic code: a work in progress, if you missed this interesting lecture you can listen to the podcast.

At the time of its elucidation the genetic code was suggested to be universal in all organisms, and the result of a ‘frozen accident’ unable to evolve further even if the current state were suboptimal. How do we see the genetic code today – 40 years after the familiar ‘alphabet’ with 20 amino acids was established? Of course, the ‘genetic code’ is the product of its interpretation by the translational machinery and it is only static as long as the components of this machinery do not evolve or are strictly conserved between organisms. Professor Soll, with over 470 scientific publications, has led the team which discovered selenocysteine and pyrrolysine, the 21st and 22nd amino acids which are directly inserted into growing polypeptides during translation. Based on the realization that protein plasticity is a feature of living cells, man-made expansion of the genetic code has begun by adding non-standard amino acids to the repertoire of the cell. Professor Soll will discuss these present evolutionary developments and how they underpin the creation of new organisms in the realm of synthetic biology.

The 3rd Bob Symons lecture is named in honour of the former Emeritus Professor in Plant Science at the Waite. Professor Symons had a long and distinguished career with the University of Adelaide, joining the University in 1962. The main research by Professor Symons between 1962 and 1990 in the Department of Biochemistry focused upon understanding the structure and function of viral nucleic acids in relation to infectivity and the development of plant disease. However, he also contributed significantly to the understanding of protein synthesis and ribozyme activity. Professor Symons was also responsible for commercial applications of his research leading to the establishment of the first Australian company to produce and market molecular biological for research. In 1991, Professor Symons moved his research to the Waite Campus where he focused upon viral diseases of grapevine and established Waite Diagnostics which still provides a service to grape growers in the diagnosis and control of grapevine pathogens. He retired in 2002 due to ill health and passed away in October 2006.
