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.

Distant star formation in the faint radio sky
One of the key quests in astronomy is to study the growth and evolution of galaxies across cosmic time. Radio observations provide a powerful means of studying the formation of stars and subsequent buildup of distant galaxies, in a way that is unbiased by the presence of dust.

Wat Darwin niet kon zien: Expeditie gaat op zoek naar onzichtbaar leven op Galapagos
Een internationaal onderzoeksteam gaat op jacht naar onzichtbare soorten op de Galapagoseilanden. De diversiteit onder bacteriën en andere microscopisch kleine organismen is niet meteen te zien, maar wél essentieel voor de natuur. Zoals voor ‘reuzenmadeliefjes’: bedreigde inheemse planten.

Richting geven aan plantengroei en -ontwikkeling
Ook planten maken groeihormonen aan, en kennen een proces van veroudering. Het bestuderen van de genen en de mechanismen hierachter is nuttig voor gewasveredeling en landbouw, maar ook voor medisch onderzoek. Dat stelt Remko Offringa, hoogleraar Ontwikkelingsgenetica van Planten.
