Functional characterization and unraveling the Gene Regulatory Networks (GRNs) of HD-Zip transcription factor HB40 (and HB22) in Arabidopsis
In this Ph.D. thesis, we characterized two novel upstream regulators of JUB1, HB40, and HB22, in Arabidopsis thaliana. In Chapter 2, we described functions of HB40 in modulating growth and development via the regulation of JUB1 and GA inactivation genes GA2OXs.

Linking the gene regulatory network with the functional physical structure of whole-genome engineered Arabidopsis mutants : an HR-MAS NMR-based
Climate change is a challenge for both current and future generations. New biological resources have to be developed in order to meet the demand for energy as well as the demand for food.

Discovery and exploitation of the transcriptional regulatory system of pectinases in Aspergillus niger
Pectin is a plant cell wall polysaccharide made of mainly D-galacturonic acid (GA) subunits. The potency of the filamentous fungus Aspergillus niger to naturally secrete high amounts of pectinases to degrade pectin has been utilized for the industrial production of pectinases.

Horizontal gene transfer and spreading of biosynthetic gene clusters and antimicrobial resistance
Biosynthetic gene clusters (BGCs) for natural products are widespread in microbial genomes, and they are rapidly exchanged. This research assesses the factors that control the spread of BGCs and resistance genes in nature. This includes risk assessment for the spread of engineered DNA in nature.

Transnational networks and domestic agencies
This dissertation studies how domestic regulatory agencies and the officials representing them are influenced by and deal with the increasingly complex transnational environments in which they have come to operate. Based on (social) network analysis it demonstrates how decisions of domestic agencies…

Stakeholder engagement as a conduit for regulatory legitimacy?
Stakeholder engagement practices are on the rise in regulatory governance. This raises an important question regarding implications for regulatory legitimacy. Engagement mechanisms are not by default legitimizing: Even when initiated to tap into an array of ‘benevolent’ desiderata, unless carefully…

The promise of bureaucratic reputation approaches for the EU regulatory state
Reputation literature has provided crucial insights about the evolution of the US regulatory state. Daniel Carpenter’s influential account painstakingly demonstrates the relevance of reputation to bureaucratic ‘power’ and to early institutional state-building in the US context. We argue that adopting…
