The Upotato Plan-genome design of potato diploid hybrid with true seed
Sanwen Huang obtained his Ph.D. in the Laboratory of Plant Breeding at Wageningen University in 2005 and currently acts as the Director General of the Agricultural Genomics Institute, Chinese Academy of Agricultural Sciences.
He plays a leading role in international vegetable genome projects, organizing the International Genome Consortia to sequence cucumber, tomato, and potato. His lab also constructed genome variation maps for cucumber, melon, tomato, and potato, which provide a theoretical framework for germplasm utilization. He identified key genes in the domestication and improvement of these crops and develop a multi-omics methodology to understand the impact of human selection to flavor and quality. He launched the “Upotato Plan”, which aims to transform potato from a clonally propagated, tetraploid crop to a true-seed-propagated, diploid crop, using genomic design breeding.
He has published over 100 papers, including in Cell, Nature, Science, and Nature Genetics. In 2015, he was awarded with the Grand Challenge 2015—Young Scientist Award from the Bill & Melinda Gates Foundation. In 2016, he was awarded with Basic Science Award from the Zhou Guang Zhao Foundation. In 2018, he was awarded the “Science and Technology Progress Award” by the Ho Leung Ho Lee Foundation and the National Natural Sciences Awards of China.

The mission of Phytophthora: explore, invade and manipulate
Francine Govers is a professor in Phytopathology at Wageningen University, the Netherlands. Her goal is to unravel the biology and pathology of Phytophthora pathogens and their interaction with plants. Phytophthora infestans is renowned for causing the Irish potato famine in the 1840s and its impact on world history.
Today late blight is still a major problem worldwide and control depends on intensive spraying regimes, every 5-7 days. In 1990, when Govers started her career in phytopathology, the awareness that Phytophthora is not a true fungus was just emerging. Oomycetes, the class that comprises the genus Phytophthora, evolved independently of fungi. Yet, they occupy similar ecological niches and also their weaponry for plant infection is comparable including the exploitation of effectors to suppress host defense. Nevertheless, there are remarkable differences. In her presentation Govers will highlight several unique features that illuminate the success of Phytophthora species as pathogens. Examples are the massive expansion of gene families encoding host specific RXLR effectors, the counterparts of resistance proteins and instrumental in R gene discovery, and alternative signaling pathways and novel cytoskeleton structures, pointing to potential targets for novel oomicides.

Potatoes in organic farming – perspectives, challenges and constraints
Christian Bruns has been involved with organic farming in Germany, Europe and worldwide for 25 years. His research focused on the optimisation of crop production in organic farming under an interdisciplinary systems approach with emphasis on potato cultivation, the efficient integration of legumes as well as the management of organic matter with special consideration of plant protection aspects. Part of the research therefore consists in the adaptation of control systems for late blight to the specific conditions of nitrogen management and supply in organic farming systems, and the control of Rhizoctonia solani in potatoes.
Potato wart disease management and resistance breeding: a genomics approach
Jack Vossen finished his PhD in 1998 on the fungal model system Saccharomyces cerevisiae (bakers- and brewers-yeast). As a post-doc he moved to study fungal disease resistance in tomato plants; First I-2 mediated resistance against Fusarium oxysporum and later Cf-4 mediated resistance against Cladosporium fulvum.
Since 2006 he is working on disease resistance in potato. Initially, he only worked on Phytophthora infestans and cloned several late blight resistance genes like R8, R9a, and Rpi-ber. Later he also initiated research to study resistance against other potato diseases like wart disease and soft-rot, caused by Synchytrium endobioticum and Pectobacteriaceae, respectively.
His research is embedded in the Plant Breeding group at the Wageningen University and Research. His team currently consists of 5 PhD students and two technicians. He authored more than 60 papers in peer reviewed journals.
Genetic approaches to increasing disease resistance in potato
Jonathan D G Jones FRS is a leading researcher in plant/microbe interactions. He graduated in Botany from Cambridge (1976) and completed his Ph.D. on cereal chromosomes supervised by Dick Flavell at the Plant Breeding Institute, Trumpington, in 1980.
Dr. Jones was a postdoc with Fred Ausubel at Harvard University 1981-2, working on symbiotic nitrogen fixation. From 1983-1988, he worked in the private sector at a startup agbiotech company (Advanced Genetic Sciences, Oakland, California). In 1988, he became one of the first recruits at The Sainsbury Laboratory, Norwich, UK, where he has twice been Head of Laboratory. He investigates plant disease resistance genes and mechanisms, and also how pathogens suppress host defences to cause disease.
Dr. Jones was elected a Professor at the University of East Anglia in 1997, a member of EMBO in 1998, a Fellow of the Royal Society in 2003, and Foreign Associate of US NAS in 2015.

Development of Diploid Germplasm for Variety Development
David Douches has been conducting potato breeding and genetics he has an active potato breeding program directed toward the development of improved cultivars in Michigan for 32 years. The focus of the program is to develop new cultivars for Michigan’s potato industry by integrating new genetic engineering techniques with marker-based and conventional breeding efforts. Key traits targeted for improvement insect resistance, disease resistance to scab, late blight, PVY, and chip processing from long-term storage. A diploid potato breeding effort was established with the goal of transforming potato breeding from its historically conventional tetraploid breeding methods. The key to this process is creating diploid germplasm that is self-compatible so that inbred lines can be developed. Gene editing of the S-RNase locus has also achieved self-compatibility. David Douches has collaborated with many research programs to train and support SNP-based studies in potato such as QTL mapping, germplasm diversity, pedigree analysis and GWAS. He is the project Director for the USAID Feed the Future Biotechnology Potato Project (FtF BPP) to develop late blight resistant 3-R-gene potatoes for Bangladesh and Indonesia.

Potato crop nitrogen status monitoring with spectral sensors : last decade developments and implementation for N fertilisation management
Jean-Pierre Goffart currently works at the Department of General Direction of Walloon Agricultural Research Centre CRA-W (Gembloux, Belgium), as Deputy General Director. J.P. does research in agronomy, crop physiology and crop fertilization, mainly of the potato crop for 30 years. He developed research on the use of spectral methods and sensors handheld or embedded on machines, UAVs and satellites to assess crop nitrogen status to be integrated in Decision Support Systems on nitrogen fertilizers management at field level, also integrating intra-field variability. Different optical/NIR sensors and associated platforms supplying leaf and canopy reflectance and leaf chlorophyll fluorescence were investigated such as chlorophyll meters, radiometers and fluorimeters. The focus was on nitrogen as an essential element in photosynthesis and several plant-growth processes, aiming to help farmers improving the potato mineral N fertilisers use efficiency to improve tuber yield and quality, and to reduce production costs and air and water pollution.
