New Intron Splicing Code Revealed in Tunicates (23.10.2019)
A Sars study shows an extraordinary case in which >90% introns have unusual and highly variable splice sites. A new splicing code appeared, which required an evolution of the splicing machinery.

Gap junction 鈥� dependent coordination of intercellular calcium signaling during early embryogenesis of Oikopleura dioica
Choreographed Calcium Signals (20.06.2019)
How do cells in the early embryo coordinate their development to create the different tissues of the body? We have found that rapid changes in calcium levels travel from cell to cell in a choreographed wave, and that disrupting this wave leads to abnormal development.

Small bricks to rapidly enlarge genomes (11.04.2019)
The tunicate larvacean Oikopleura dioica, a flagship of Sars Centre science, is well known for having a remarkably small and compact genome. However, sequencing of related species has revealed immense variations in genome size among larvaceans, up to 12X. Research at the Sars Centre and at the Institut de Genomique Fonctionnelle de Lyon, published in Current Biology (Naville, Henriet et al.), now... Read more
Profiling Ciona Behaviour (20.02.2019)
