POSTHARVEST PATHOLOGY SYMPOSIUM 2017 SPEAKERS
Dr. Wisniewski, Michigan State University , United States of America
Dr. Wisniewski has achieved major scientific accomplishments in two divergent topics of research on fruit trees: environmental stress and postharvest biological control. He is a leading authority on deep supercooling in woody plants and is recognized for developing high-resolution infrared thermography to study ice nucleation. He co-patented a method of frost protection that utilizes a hydrophobic barrier and provided the first evidence of the association of dehydrin protein and its cryoprotective properties with levels of cold hardiness in peach trees, grapes, and other woody plants.
He partnered with the University of Illinois to produce the first 40,000 long-oligo, unigene apple microarray for conducting functional genomic studies and has collaborated on a genetic mapping project to identify QTLs for economically-important traits in the apple progenitor species, Malus sieversii. In his biocontrol research, he played a major role in developing the first, yeast-based biocontrol agent (Aspire™), was the first to demonstrate the ability of yeast to parasitize fungi, and demonstrated the ability of various salts to enhance biocontrol activity. He has been issued several patents in this field, and was awarded both the Federal Lab Consortium and USDA-ARS Technology Transfer Award in 1996. He was elected as an ASHS Fellow in 1998, and chosen as the USDA-ARS Early Career Scientist in 1992 and USDA-ARS-NAA Senior Scientist in 2009. He has served as an Associate Editor for the J. Amer. Soc. Hort. Sci., Frontiers in Plant Science, and other journals. He has also served as a member of the Technical Advisory Committee of U.S.-Israel Binational Agricultural Research and Development (BARD) Fund. He has published over 240 peer-reviewed journal articles and 32 book chapters and has had numerous speaking invitations.
He co-edited “Plant Cold Hardiness: From the Laboratory to the Field,” and received the ASHS Cross Commodity Publication of the Year Award in 2000. He was also awarded the Outstanding Researcher Award by ASHS. His ice nucleation research is included in a leading college textbook on Plant Physiology and his scientific photographs have won an award from the Polaroid Corp. and were part of an exhibit at the Andy Warhol Museum. He has reviewed programs on biological control in New Zealand, Colombia, and Uruguay and participated in advanced courses on plant cold hardiness in Finland and Canada. He has also assisted in teaching courses on biological control in Uruguay several times.
Along with his colleague, Samir Droby (ARO, Israel), he established the ISHS working group on Alternative Methods for Managing Postharvest Diseases and this working group has sponsored four international conferences in the past eight years and has become a principle outlet for sharing the latest advances in this critical field of research. In 2016, he was awarded Lifetime Honorary Membership in the Canadian Phytopathological Society in recognition for his accomplishments and leadership in postharvest disease research. In 2017, he was awarded the Martin Bukovac Lectureship at Michigan State University in recognition for his contribution to fruit science. He has served on the scientific and organizational committees of international conferences has mentored numerous undergraduate and graduate students, as well as postdoctoral scientists, from around the world.

Prof. Dov Prusky, Agricultural Research Organization, The Volcani Center, Israel
Research in the laboratory focuses on understanding the basic processes underlying the interactions between fruits and pathogenic fungi. These interactions are known to involve the production and recognition by both plant and pathogen of a variety of signals, but it is frequently difficult to distinguish between the indispensable and the superfluous components of the complex process of infection.
In my laboratory, we use chemical, biochemical, genetic, and molecular biological techniques to identify and critically evaluate putative disease factors. Our emphasis is on the biochemical and molecular mechanisms that are controlled by fungal virulence and fruit resistance factors.
