Database Description

GermOnline is a subject oriented cross-species community annotation knowledgebase that provides access to microarray expression data from experiments relevant for the mitotic and meiotic cell cycle as well as gametogenesis in yeast and higher eukaryotes. Moreover, GermOnline integrates knowledge about genes important for meiosis, gametogenesis and fertility that is provided and updated by members of the scientific community in collaboration with professional curators.

Recent Developments

We have recently included an online microarray data uploading module. This enables scientists to use GermOnline as a searchable array database for their work. GermOnline was recommended by Faculty of 1000 ( and it was included into the list of high-quality scholarly websites accessible via Current Web Contents produced by Thomson ISI.


We thank Roger Jenni (BioPhIT), Rainer Poehlmann ([BC]2) and Dean Flanders (FMI) for excellent IT infrastructure support. This work is supported by the Swiss Institute of Bioinformatics.
