Transcriptomic analysis implicates ABA signaling and carbon supply in the differential outgrowth of petunia axillary buds.

Plants need to balance growth of axillary buds into branches to fit with available resources while allowing some buds to remain dormant to grow after the loss of plant parts or in response to a change in environmental conditions. Here we demonstrate that different buds on the same plant with different developmental potentials have quite different transcriptome profiles.
