Speaker Profile

Dr. Maarten Jongsma
Senior Research Ccientist, Wageningen Plant Research
Wageningen University and Research, The Netherlands

Profile:
Dr Maarten Jongsma obtained an MSc with distinction in Molecular Sciences at Wageningen University in the Netherlands and graduated in 1995 at the same university with a PhD on the role of plant protease inhibitors in defence against insects. Since then he has worked at Wageningen Plant Research leading a range of often international projects and programs on different topics with mostly EU and Asian partners from academia and industry. He published >100 papers, h-index 49. After an initial focus on plant genetic engineering he shifted towards discovery of the biochemical and genetic basis of natural plant traits involved in defence, human health and flavour. To enable this he developed two novel phenotyping platforms, EntoLab and Receptomics, that are now in the process of commercialization. He is also involved in the validation of flavour and health traits of plants with human taste panels and clinical trials. (https://scholar.google.com/citations?user=7v4U8GwAAAAJ)

Abstract:
Receptomics and EntoLab: two novel video platforms enabling breeding of vegetables for (i) human taste and health benefits and for (ii) identifying insect resistance and susceptibility traits.

I have developed the hardware for two novel htp phenotyping platforms which record series of videos of (i) the ‘movement behaviour’ (16 hrs) of either ca. 150 insects each in their own arena on top of leaves arranged in a tray of 20x20 cm (www.noldus.com/entolab) or (ii) imaging the ‘activation behavior’ (5 min) of a 300 spot receptor cell array on a chip of 1 cm2 in response to injected samples (www.receptomics.com). With dedicated software we extract the statistical means of >30 behaviour parameters of the insects, and, for the other platform, the responses of >30 receptors. Each of these parameters/signals are individually or collectively associated with e.g. SNPs, metabolites or taste panels. Recently, the EntoLab software suite was expanded to perform stand-alone GWAS and QTL studies with the behavior statistics, so that genotype specific behavior on leaf series could be associated to QTLs of resistance and susceptibility. Discussed will be a study of a maize MAGIC population with aphids, and how we now plan to do the same in a receptor study which is open for industry participation (Sept 1st deadline, contact me before the end of June).

• HOST-IT: optimizing host cells for receptomics to quantify healthiness and flavour of extracts
• TRACKGENE: insect behavior translated into dynamic QTLs using the EntoLabTM platform

Dr. Byoung-Cheorl Kang
Professor, School of Plant Science and Center for Plant Molecular Genetics and Breeding Research
Seoul National University, South Korea

Profile:
Byoung-Cheorl Kang works as a professor at Seoul National University, holding appointments in the Department of Plant Science, the Laboratory of Horticultural Crops and Breeding and the Vegetable Research Center. He obtained his Msc (1990) and PhD (1999) from Seoul National University. He was a Post-doctoral Fellow (2000 to 2012) and Research Associate (2013 to 2015) at Cornell University, USA. His research has focused on developing genetic materials for molecular breeding for vegetable crops, especially in the genus Capsicum. A primary research topic in his lab is the identification of genes controlling disease resistance and secondary metabolite biosynthesis in peppers using various genomic tools. Prof. Kang has published more than 140 peer-reviewed papers in international journals.
