Efficient RNA extraction methods are needed to study transcript regulation. Such methods must lyse the cell without degrading the genetic material. For cyanobacteria this can be particularly challenging because of the presence of the cyanobacteria ce

Background: Genotypic diversity within cyanobacteria populations, partly driven by horizontal gene transfers, is a key factor of their colonization success, allowing them to cope with spatio-temporal fluctuations of the environmental conditions. By p
