SUMMARY:Large-scale innovative approaches for natural products discovery
DESCRIPTION:Nigel J. Mouncey\, J. Dinglasan\, D. Doering\, K. Kukil\, H. Otani\, D. Udwary \nU.S. Department of Energy Joint Genome Institute\, Lawrence Berkeley National Laboratory\, Berkeley\, USA nmouncey@lbl.gov \nThe galaxy of natural products comprises a large family of diverse and complex chemical entities that have roles in both primary and secondary metabolism\, and today >36\,000 natural products have been characterized. We are seeing a resurgence of activity in exploring secondary metabolites for a wide range of applications\, due to not only increasing antibiotic and pesticide resistance\, but the advent of next-generation genome sequencing and new technologies to investigate natural product biosynthesis. There remains a treasure trove of natural products that remains to be unlocked. At the JGI\, we have developed new tools and processes for identification of novel biosynthetic gene clusters from isolate genomes and metagenomes and complementing these with a suite of new experimental platforms to access the products of these clusters. We have built a new secondary metabolite biosynthetic cluster prediction pipeline and a data portal\, the Secondary Metabolism Collaboratory\, as a new community-centric resource. Furthermore\, we have developed capabilities to understand how secondary metabolite biosynthesis is regulated\, expression systems in native and heterologous hosts and with cell-free technology to access unexplored chemistry and used these to explore secondary metabolites from a range of organisms. I will share our recent developments in unlocking the Earth’s Secondary Metabolome.

SUMMARY:BIC Seminar: Prof. Rainer Hedrich
DESCRIPTION:BIC Seminar: Prof. Rainer Hedrich \nProbing plant signalling via Channelrhodopsin optogenetics \nDate: 28 April 2026 \nTime: 14:50 \nLocation: C0333\, Orion\, Wageningen Campus \nAbstract: \nMembrane electrical excitation\, often associated with the transient rise in cytosolic Ca2+ and H+ concentration\, represent universal signalling elements that couple a wide range of stimuli to their characteristic responses\, including in plants. Despite decades of intensive research\, many of the signal transduction elements involved in Ca2+ and pH signalling are yet to be elucidated. Progress has been hampered due to our inability to trigger defined changes in cytosolic Ca2+ concentration\, without provoking changes in plasma membrane electrical properties. Over the past 5 years\, new game-changing ion channel optogenetic tools have been introduced into plants to answer long-standing questions in plant biology. \nIn this presentation I will describe how we have engineered the light-gated ChannelRhodopsins CHRs selective for anions (ACR1)\, H+ (KCR2) or Ca2+ (XXM2.0) and to obtain stable expression in Arabidopsis and tobacco plants. These tools provide us with the unique opportunity to non-invasively induce voltage\, Ca2+ and H+ signals in guard cells as well as any plant cell/tissue/organ type of interest. Furthermore\, I will describe how CHRs provide a valuable tool to non-invasively excite the plasma membrane\, trigger H+ or Ca2+ influx\, and provoke H+ or Ca2+ induced Ca2+ release. This allows to study the interrelation between plant pH and Ca2+ signalling on one side\, and electrical excitation on the other. Depending on the CHR and stimulation features (pulse number\, length\, and frequency) one can remote control single cell action\, long-distance transport as well as growth and shape or plant organs. Our findings challenge established paradigms relating to the way proton\, calcium\, and voltage signalling are interconnected in plants and rethink of mechanisms involved.

SUMMARY:Understanding the genetic mechanism of Brassica napus resistance against cabbage stem flea beetle
DESCRIPTION:Understanding the genetic mechanism of Brassica napus resistance against cabbage stem flea beetle\nRachel Wells\, Department of Crop Genetics\, John Innes Centre \nWednesday April 15th; time 16.00; location Wageningen\, Radix W01\nContact: Guusje Bonnema\, Plant Breeding\, WUR \nRachel’s research involves the identification of genetic resistance to Brassica pests and disease\, with a strong focus on cabbage stem flea beetle (CSFB). Her research group uses captive colonies\, to study CFSB development and genetics\, and controlled and field plant variety screens for both adult and larval CSFB damage in Brassica napus and related species\, such as Sinapis alba. These experiments can be used to look at plant-pest interaction and ultimately determine the genes and mechanisms associated with pest resistance. This work is complemented by collaboration with the University of Hertfordshire on light leaf spot\, focussing on mutation breeding and genome editing to target disease susceptibility.

SUMMARY:Sebastian Bargmann - To Cell and Back: the study of plant regeneration from protoplasts
DESCRIPTION:Speaker: Dr Sebastian Bargmann Virginia Polytechnic Institute \nLocation: Wageningen Campus\, Radix\, meeting room W1 \nTo Cell and Back: the study of plant regeneration from protoplasts \nRecalcitrance in tissue culture is a significant bottleneck in the application of biotechnological approaches for crop trait improvement. The ability to regenerate a fertile plant from genetically modified cells is essential to many methodologies. Non-transgenic gene editing through transient transformation and subsequent regeneration of protoplasts is especially hampered by genotype dependence in regenerability. We have established a protoplast culture system in Arabidopsis to study the fundamental basis of regeneration. Our method allows us to track protoplast division and microcallus development microscopically over time. In addition\, we can use single-cell and single-colony transcriptomic analysis to characterize the gene-regulatory networks that guide re-entry into the cell cycle and subsequent growth and differentiation. Lastly\, we have studied the ability of morphogenic transcription factors to enhance regeneration by mapping their direct and indirect downstream effects using the TARGET-seq system (Transient Assay Reporting Genome-wide Effects of Transcription factors). A better understanding of the mechanisms involved in protoplast regeneration and the development of methods to enhance regeneration efficiency can broaden the applicability of biotechnological tools to improve sustainability and resilience of our agricultural systems. \nFor more information please contact Dr Renze Heidstra (Renze.Heidstra@wur.nl)

SUMMARY:GLS seminar Rebecca Mosher - RNA-directed DNA Methylation: a maternal influence during seed development
DESCRIPTION:GLS seminar by Rebecca Mosher – RNA directed DNA Methylation: a maternal influence during seed development\nSpeaker: Rebecca Mosher (Becky Mosher) University of Oxford\, Oxford\, UK \nDate: Tuesday 25 November 2025 \nTime: 15:00 -16:00 \nLocation UvA Science Park 904\, Room C0.05 \nHost: Maike Stam \n*followed by a meet up with the speaker for GLS master students\, PhD candidates\, and postdocs of the plant groups (hosted by Juliette Aubert) \n24-nt small interfering (si)RNAs establish DNA methylation at thousands of genomic loci in a process called RNA-directed DNA Methylation (RdDM). RdDM is dispensable for growth and development in Arabidopsis\, but is required for reproduction in many other plant species\, particularly historically outbreeding species. In Brassica rapa\, the embryo and endosperm abort if RdDM is disrupted in the maternal sporophyte\, implying communication between maternal and filial tissues. During reproduction\, 24-nt siRNAs are particularly abundant in maternal sporophytic tissue such as the seed coat\, largely due to overwhelming expression from a small number of “siren” loci. Siren loci account for over 90% of siRNAs in ovules and early seeds\, and many siRNAs are produced from gene fragments embedded in these loci. We recently demonstrated that these siRNAs trigger methylation at homologous protein-coding genes\, and in some cases this trans-methylation impacts expression of the target gene. In the endosperm\, siren siRNAs are maternally biased\, suggesting that siRNAs might be transported to\, and function in\, filial tissues. Together\, these observations suggest that maternally-derived siren siRNAs might methylate protein-coding genes in filial tissues to influence seed development. \n  \nTwo papers linked to the seminar: \n\nGrover JW et al\, PNAS 2020\nBurgess D et al\, Plant Cell 2022
