Local and systemic signalling controls which axillary buds grow.

Caption

Axillary buds are located at the base of each leaf. Initially dormant, each can grow into a branch. To study how branching is regulated by local signalling within each bud and by systemic signalling from other buds, we used stem sections with two axillary buds and their associated leaves (left). This signalling network influences, for example, whether one bud grows and rapidly inhibits the other (middle), or whether both buds grow simultaneously (right).
