Rate My Professor Vanessa Melino

Dr. Vanessa Melino is a Lecturer in the School of Science at the University of Newcastle, Australia, within the College of Engineering, Science and Environment. She holds a Doctor of Philosophy from the University of Adelaide. Her professional career encompasses diverse roles advancing plant science. From 2009 to 2012, she served as a postdoctoral researcher at Murdoch University, investigating rhizobia symbiosis, clover, and nitrogen genomics. Subsequently, from 2012 to 2018, she was a postdoctoral fellow at the Australian Centre for Plant Functional Genomics, University of Adelaide, focusing on wheat nutrition, root architecture, nitrogen use efficiency, uptake, recycling, and ureide metabolism. She then held a Research Fellowship from 2018 to 2020 at the School of Agriculture, Food and Ecosystem Science, studying barley root biology, nitrogen use efficiency, and root endodermal barriers. Prior to her current position, Melino was a Research Scientist from 2020 to 2024 at the King Abdullah University of Science and Technology's Centre for Desert Agriculture, leading projects on halophyte domestication, saline agriculture, and reducing nitrogen pollution with nitrification inhibitors. In recognition of her contributions, she received the University of Adelaide Vice-Chancellor's Academic Women's Researcher Excellence Award in 2017.

As a plant physiologist and molecular biologist, Vanessa Melino's research centers on domesticating halophytes, particularly Salicornia species, as seed oil crops for arid, saline environments using seawater irrigation and low nitrogen inputs. Her team has established a global germplasm collection, sequenced genomes of multiple species, conducted field trials in the Middle East, and bred lines with enhanced vigor, oil content, and fatty acid profiles. She explores salt tolerance mechanisms, such as the sodium/proton antiporter SbiSOS1 for vacuolar sodium sequestration and the intrinsically disordered protein SALTY for stabilizing protein translation under salt stress, collaborating with protein biophysics experts. Melino also advances crop nitrogen use efficiency, from biofertilizers and rhizobia for legumes to controlled-release fertilizers and internal nitrogen recycling from RNA and purines in cereals. Notable publications include 'Salt-Tolerant Crops: Time to Deliver' (Annual Review of Plant Biology, 2023), 'SOS1 tonoplast neo-localization and the RGG protein SALTY are important in the extreme salinity tolerance of Salicornia bigelovii' (Nature Communications, 2024), 'Strategies for engineering improved nitrogen use efficiency in crop plants via redistribution and recycling of organic nitrogen' (Current Opinion in Biotechnology, 2022), 'The intersection of nitrogen nutrition and water use in plants: new paths toward improved crop productivity' (Journal of Experimental Botany, 2020), 'RNA Catabolites Contribute to the Nitrogen Pool and Support Growth Recovery of Wheat' (Frontiers in Plant Science, 2018), and 'Opposite fates of the purine metabolite allantoin under water and nitrogen limitations in bread wheat' (Plant Molecular Biology, 2019). Currently, she leads an ARC Discovery Grant (2025-2028) titled 'Bioengineering Salt Tolerant Proteins: Crop Solutions from Wild Plants' and supervises projects on Salicornia genomics and RNA-binding proteins in salt stress. Her work contributes to WHO Sustainable Development Goal 2 by tackling water scarcity and nitrogen pollution for sustainable agriculture.
