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.

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.

Plastic nanoparticles make larval zebrafish hyperactive
Nanoplastics influence the behaviour of larval zebrafish, says new research by the Institute of Biology Leiden (IBL) and the Institute of Environmental Sciences (CML). The researchers observed that a certain type of nanoparticles leads to stress reactions in the sugar balance, resulting in hyperactivity…

Novel role of the AT-HOOK MOTIF NUCLEAR LOCALIZED 15 gene in Arabidopsis meristem activity and longevity
Plant architecture has distinct forms in different plant species, but also within a species the finalarchitecture of a plant is determined by its gradual development and changes therein induced by environmental conditions during the plant’s life cycle.

Leiden researchers discover genes that affect spread of breast cancer
Researchers at Leiden University have mapped genes that cause breast cancer cells to migrate. The Leiden toxicologists Professor Bob van de Water, Dr Wies van Roosmalen, Dr Sylvia E. Le Dévédec and colleagues studied 1500 individual genes. They found eight, including the SRPK1 gene, that regulate the…
