Impact of plant hormones on growth and development of actinobacteria
Plants are colonized by an astounding number of microorganisms that can provide different life-support functions, including nutrient acquisition and protection against (a)biotic stresses like drought or pathogen attack.

Spatial populations with seed-bank
In populations with a seed-bank, individuals can temporarily become dormant and refrain from reproduction until they can become active again. The repository of all dormant individuals in the population is called the seed-bank. Seed-banks are observed in many taxa, including plants, bacteria and other…

Another Brick in the Wall: The role of the actinobacterial cell wall in antibiotic resistance, phylogeny and development
Streptomyces are multicellular, Gram-positive bacteria in the phylum of actinobacteria which produce a high amount of bioactive natural products of which the expression is tightly coordinated with the life cycle.

Onderzoekers gaan de strijd aan met antibioticaresistente bacteriën
Wanneer een bacterie resistenter wordt voor het ene antibioticum, wordt het soms gevoeliger voor een ander. Om deze wisselwerking beter te begrijpen, brachten onderzoekers van het Instituut Biologie Leiden (IBL) en het Leiden Academic Centre for Drug Research (LACDR) onder leiding van Daniel Rozen en…
