ABSTRACT

Plant shoot systems give rise to characteristic above-ground plant architectures. Shoots are formed from axillary meristems and buds, whose growth and development is modulated by systemic and local signals. These cues convey information about nutrient and water availability, light quality, sink/source organ activity and other variables that determine the timeliness and competence to maintain the development of new shoots. The information is then translated into a local response, in meristems and buds, of growth or latency. I will discuss the emerging picture and the molecular genetic mechanisms underlying this decision, with a particular focus on a TCP transcription factor, BRANCHED1, that controls several gene regulatory networks induced inside the buds, and on genes controlling hormone signalling that modulate this process.
