“Epigenetic control of gene activation in Arabidopsis flower development”

 

Abstract:

Developmental switches and cell fate decisions in plants require coordinated changes in the activities of thousands of genes. Concerted activities of transcription factors and epigenetic regulators are essential for spatiotemporal control of gene expression programs. Polycomb repressive complex 2 (PRC2) mediates the epigenetic memory of gene silencing in plant development, thereby restricting gene activities to specific cell types and developmental stages. RELATIVE OF EARLY FLOWERING 6 (REF6) is a Jumonji (JMJ)-type histone demethylase that counteracts PRC2-mediated gene silencing in plants. Research in my group recently showed that REF6 and its two close paralogs determine spatial ‘boundaries’ of the repressive histone H3K27me3 mark in the genome, and control the tissue-specific release from PRC2-mediated gene repression. Targeted mutagenesis revealed that these histone demethylases display pleiotropic, redundant functions in plant development, several of which depend on trans factor-mediated recruitment. Thus, JMJ-type histone demethylases restrict repressive chromatin domains, and contribute to tissue-specific gene activation via complementary targeting mechanisms.

„Urban and Peri-urban agriculture in the EU“

Abtract:

The presentation will give a state of the art overview on urban agriculture and peri-urban agriculture (UPUA), the diversity of phenomena, motivations, distinctive features, benefits and limitations. UPUA is contextualized in relation to societal and economic transformations, EU strategic objectives, policies and regional food system approaches. Using best practice examples, the presentation demonstrates the need for an improved integration of UPUA into the policy agenda across sectors, domains and governance levels.

Metabolic differences in chromosome substitution lines of Arabidopsis thaliana received by Reverse Breeding”

 

Abstract:

Traditionally, hybrid seeds are produced by crossing selected inbred lines. A recent method for haploid production in the model plant A. thaliana (Ravi and Chan, 2010) enabled us to provide a proof of concept for an alternative strategy: Reverse Breeding, a new approach that simplifies meiosis such that homozygous parental lines can be gene-rated from a vigorous hybrid individual (Dirks et al. 2003, 2009). We silenced DMC1, which encodes the meiotic recombination protein DISRUPTED MEIOTIC cDNA1, in hybrids of A. thaliana, so that non-recombined parental chromosomes segregate during meiosis (Wijnker et al. 2008, 2012). We then converted the resulting gametes into adult haploid plants, and subsequently into homozygous diploids, so that each contained half the genome of the original hybrid. From 36 homozygous lines, we were able to identify a complete set of chromosome-substitution lines. Some of those lines were analyzed for metabolic differences by LC-MS.  Among others, several glucosinolates have already been identified to decrease in one of the chromosome substitution lines. Elucidating the genetic differences between the parental lines can explain those metabolic changes.

„Fungal root endophytes and their potential role for improving agriculture under nutrient and drought stress”

 

Abstract:

All terrestrial plants in natural ecosystems are assumed to have a symbiotic relationship with fungi, with particular importance attached to fungal root endophytes. This highly diverse group of fungi can have a profound impact on plant communities and their fitness by initiating tolerances against abiotic and biotic stressors. The aim of the project is to characterize selected fungal root endophytes from plants of disturbed sites (reclamation sites) or extreme habitats to characterize these fungi and to investigate their effect on the growth of agricultural plants under nutrient and drought stress.

“Fungal Production – From slow to fast, between 10°C and 40°C”

Abstract: Several production systems using filamentous fungi will be compared. Traditional mushroom cultivation will be discussed for Lentius edodes known as Shii-take. Some aspects concerning vitamin overproduction will be shown for the hemiascomycete Ashbya gossypii. Conclusions will lead to a more robust and faster production system based on selective cultivation conditions and run at 40° with Malaysian palm oil  (EP3363891).
