Abstract As part of their modular development, plants continuously adapt their shoot branching architecture according to environmental conditions. This occurs by regulating the activity of axillary buds established in each leaf axil. Whether a bud grows into a shoot depends partly on the presence of other active shoots, which can inhibit bud activation.

Recent analysis shows that there are currently three variants of the virus each of which are simultaneously circulating in Guinea, the outbreak’s epicentre. Two of these variants share considerable similarity to strains circulating in neighbouring Sierra Leone, indicative of several instances of reintroduction from Sierra Leone to Guinea. This data is not only useful for tracking the pathway of disease spread but is vital for vaccine optimisation.
