Jeffrey Graham (Jeff) Ellis FRS FAA (born 4 May 1953 in Adelaide) is an Australian plant scientist, and Program Leader at CSIRO Plant Industry. [1] [2]
He earned a BAgSc in 1976, and a PhD in 1981, from the University of Adelaide. [3] In 1984, as a Research Scientist in CSIRO Plant Industry, he worked on the identification of transcriptional control elements in the promoters of the maize alcohol dehydrogenase gene and the Agrobacterium T-DNA gene octopine synthase. Ellis and his research team were among the first to clone and characterize plant disease resistance genes. [4]
A genetically modified organism (GMO) is any organism whose genetic material has been altered using genetic engineering techniques. The exact definition of a genetically modified organism and what constitutes genetic engineering varies, with the most common being an organism altered in a way that "does not occur naturally by mating and/or natural recombination". A wide variety of organisms have been genetically modified (GM), including animals, plants, and microorganisms.
Rebecca J. Nelson is an American biologist and a professor at Cornell University and a MacArthur Foundation Fellow.
The Eureka Prizes are awarded annually by the Australian Museum, Sydney, to recognise individuals and organisations who have contributed to science and the understanding of science in Australia. They were founded in 1990 following a suggestion by science journalist Robyn Williams.
Jeffrey Lynn Bennetzen is an American geneticist on the faculty of the University of Georgia (UGA). Bennetzen is known for his work describing codon usage bias in yeast, and E. coli; being the first to clone and sequence an active transposon in plants, discovering that most of the DNA in plant genomes was a particular class of mobile DNA (LTR-retrotransposons); solving the C-value paradox; proposing sorghum and Setaria as model grasses; showing that rice centromeres were hotspots for recombination, but not crossovers; and developing a technique to date polyploidization events. He is an author, with Sarah Hake of the book "Handbook of Maize." Bennetzen was elected to the US National Academy of Sciences in 2004.
The Prime Minister's Prizes for Science are annual Australian awards for outstanding achievements in scientific research, innovation, and teaching. The prizes have been awarded since 2000, when they replaced the Australia Prize for science.
Sir David Charles Baulcombe is a British plant scientist and geneticist. As of October 2024 he was Head of Group, Gene Expression, in the Department of Plant Sciences at the University of Cambridge, and the Edward Penley Abraham Royal Society Research Professor and Regius Professor of Botany Emeritus at Cambridge. He held the Regius botany chair in that department from 2007 to 2020.
Jeffery Lee Dangl is an American biologist. He is currently John N. Couch Professor of Biology at the University of North Carolina at Chapel Hill.
Plant genetics is the study of genes, genetic variation, and heredity specifically in plants. It is generally considered a field of biology and botany, but intersects frequently with many other life sciences and is strongly linked with the study of information systems. Plant genetics is similar in many ways to animal genetics but differs in a few key areas.
Genetically modified mammals are mammals that have been genetically engineered. They are an important category of genetically modified organisms. The majority of research involving genetically modified mammals involves mice with attempts to produce knockout animals in other mammalian species limited by the inability to derive and stably culture embryonic stem cells.
Nagendra Kumar Singh is an Indian agricultural scientist. He is presently a National Professor Dr. B.P. Pal Chair and JC Bose National Fellow at ICAR-National Institute for Plant Biotechnology, Indian Agricultural Research Institute, New Delhi. He was born in a small village Rajapur in the Mau District of Uttar Pradesh, India. He is known for his research in the area of plant genomics, genetics, molecular breeding and biotechnology, particularly for his contribution in the decoding of rice, tomato, wheat, pigeon pea, jute and mango genomes and understanding of wheat seed storage proteins and their effect on wheat quality. He has made significant advances in comparative analysis of rice and wheat genomes and mapping of genes for yield, salt tolerance and basmati quality traits in rice. He is one of the highest cited agricultural scientists from India for the last five years.
Pamela Christine Ronald is an American plant pathologist and geneticist. She is a professor in the Department of Plant Pathology and conducts research at the Genome Center at the University of California, Davis and a member of the Innovative Genomics Institute at the University of California, Berkeley. She also serves as Director of Grass Genetics at the Joint BioEnergy Institute in Emeryville, California. In 2018 she served as a visiting professor at Stanford University in the Center on Food Security and the Environment.
Peter Michael Waterhouse is a British-Australian plant virologist and geneticist. He is a professor at the Queensland University of Technology and a Chief Investigator at the ARC Centre of Excellence for Plant Success in Nature and Agriculture.
Elizabeth Jean Finnegan FAA is an Australian botanist who researches plant flowering processes and epigenetic regulation in plants. She currently works at the Commonwealth Scientific and Industrial Research Organisation (CSIRO) as a senior scientist, leading research on the "Control of Floral Initiation", part of the CSIRO Agriculture Flagship.
Bacterial leaf streak (BLS), also known as black chaff, is a common bacterial disease of wheat. The disease is caused by the bacterial species Xanthomonas translucens pv. undulosa. The pathogen is found globally, but is a primary problem in the US in the lower mid-south and can reduce yields by up to 40 percent.[6] BLS is primarily seed-borne and survives in and on the seed, but may also survive in crop residue in the soil in the off-season. During the growing season, the bacteria may transfer from plant to plant by contact, but it is primarily spread by rain, wind and insect contact. The bacteria thrives in moist environments, and produces a cream to yellow bacterial ooze, which, when dry, appears light colored and scale-like, resulting in a streak on the leaves. The invasion of the head of wheat causes bands of necrotic tissue on the awns, which is called Black Chaff.[14] The disease is not easily managed, as there are no pesticides on the market for treatment of the infection. There are some resistant cultivars available, but no seed treatment exists. Some integrated pest management (IPM) techniques may be used to assist with preventing infection although, none will completely prevent the disease.[2]
Ian Alexander Graham is a professor of biochemical genetics in the Centre for Novel Agricultural Products (CNAP) at the University of York.
Susan J. Clark is an Australian biomedical researcher in epigenetics of development and cancer. She was elected a Fellow of the Australian Academy of Science in 2015, and is a National Health and Medical Research Council (NHMRC) Senior Principal Research Fellow and Research Director and Head of Genomics and Epigenetics Division at the Garvan Institute of Medical Research. Clark developed the first method for bisulphite sequencing for DNA methylation analysis and used it to establish that the methylation machinery of mammalian cells is capable of both maintenance and de novo methylation at CpNpG sites and showed is inheritable. Clark's research has advanced understanding of the role of DNA methylation, non-coding RNA and microRNA in embryogenesis, reprogramming, stem cell development and cancer, and has led to the identification of epigenomic biomarkers in cancer. Clark is a founding member of the International Human Epigenome Consortium (IHEC) and President of the Australian Epigenetics Alliance (AEpiA).
Brian John Staskawicz ForMemRS is professor of plant and microbial miology at the University of California, Berkeley and scientific director of agricultural genomics at the Innovative Genomics Institute (IGI).
