node initiation and proximal internode elongation are associated with

in node initiation, flowering-time genes have been repurposed to specify
the timing and duration of internode elongation. Our study provides an

suggests that plant architecture should be recognized as a collection of
dynamic phytomeric units in the context of crop adaptive evolution.},
