Jean Dominique Meunier is senior scientist at the French National Council for Scientific Research (CNRS) and is working at the Centre Européen de Recherche et d’Etude en Geosciences de l’Environnement (CEREGE) at Aix en Provence, France, since 1991. His main center of interest is the environmental biogeochemistry.


After having working on the formation and evolution of uranium deposits in sandstones, he has moved into the study of the biogeochemical cycle of Si at the earth’s surface with applications for the understanding of weathering processes, plant–water-soil interactions and anthropogenic impacts including agriculture.

Lawrence E. Datnoff is Department Head of Plant Pathology and Crop Physiology at Louisiana State University.  Over the past two and half decades, Datnoff, along with his students and colleagues, has contributed broadly and instructively to the study of the important relationship between silicon and host plant resistance. He has published extensively, building the evidence-base on effects of silicon on diseaseepidemiology, defense mechanisms, and integrated disease management.
He has played a major role in promoting this overlooked, beneficial element from a mere scientific curiosity to an agronomic and horticultural practice by helping the American Association for Plant Food Control Officials (AAPFCO) recognize silicon as a beneficial substance and the National Organic Standards Board / USDA National Organic Program recognizing its use for managing plant diseases.

Miroslav Nikolic is a head of Plant Nutrition Laboratory and teaches the rhizosphere course at the Graduate School of Agronomy of the University of Belgrade. Current research of his group centers on nutrient acquisition and transport in crops as well as on the plant response mechanisms to mineral stresses, from nutrient deficiency to the excess of different minerals.

His special focus is to understand the mechanisms through which silicon mediates (a) root responses for rhizosphere mobilization and root uptake of nutrients (e.g. phosphorus and iron) under limited conditions, and (b) transport of nutrients and other mineral elements including the regulation of transporters involved in their homeostasis at tissue, cellular and subcellular level. His team was the first one to demonstrate that silicon enhances root acquisition and shoot remobilization of iron through up-regulating the expression of key genes involved in these processes.

Naoki Yamaji is an Associate Professor at the Institute of Plant Science and Resources, Okayama University, Japan. His research mainly focuses tolerance mechanism of plants to aluminum ion toxicity in acidic soil. He and his collaborators identified a key transcription factor, ART1 for aluminum response gene expression in rice. Then they characterized downstream various tolerance mechanisms.
Recently he pointed out importance of node in graminaceous plants in terms of preferential distribution control of mineral nutrients. He found Lsi6, a silicic acid channel in rice, as a first example of transporter involved in inter-vascular transfer of nutrients in node. To date, he and his collaborators identified various transporters involved in preferential distribution of Si, P, Zn, Cd, Mn and Cu.

Ravin Jugdaohsingh gained his PhD in Chemistry at King’s College London (London, UK) on silicon and aluminium interaction and went on to carry- out post-doctoral research on silicon at King’s College London, the Medical Research Council in Cambridge and at University of Cambridge. He is one of the leading world experts on the chemistry and biochemistry of silicon and the effect of the element on health.

He has a particular interest in the role and mechanisms of action of dietary silicon in connective tissues as well as cell interactions and impact of mineral silica nanoparticles. Much of his work has been on bone in understanding the role silicon may play in the maintenance of normal bone health.

Richard Bélanger is Professor in plant pathology and holder of a Canada Research Chair in plant protection. His research endeavors have concentrated on the development of biological and non-chemical approaches to control plant diseases. Along those lines, sustained efforts have been devoted to the study of the prophylactic properties of silicon against plant pathogens with a special emphasis toward understanding the elusive properties of Si as it interacts with plants.

His research results led to the conclusions that Si benefits were significantly more manifest when a plant was exposed to a stress. In recent activities, his team has been investigating Si transporters and absorption in plants in order to optimize the application of Si through a better understanding of the genetic predisposition of plants to absorb the element.

Yongchao Liang is Professor at the College of Environmental and Resource Sciences of the Zhejiang University, China. His broad research interest includes plant silicon biology and related stress-resistance mechanisms, adaptations of higher plants to stressful environments, soil contamination and remediation, soil biology and biochemistry, and fertilization management. .

His most accomplished work on plant silicon biology ranges from Si uptake and transport to abiotic and biotic stresses He and his co-workers have demonstrated that silicon-enhanced antioxidant defense capacity is one of the major mechanisms of resistance to salinity stress and a universal mechanism of Si-enhanced resistance to abiotic stress. They concluded that both active and passive Si-uptake components co-exist in different crop specieswith their relative contribution depending on both the genotype and the external Si concentrations. His book entitled “Silicon in Agriculture: From Theory to Practice” was published by Springer in 2015.
