Other claims from this paper (6)
- Observation Bayberry knob fruit tissue is fully developed before wax accumulates.
- Observation Wax is secreted to the bayberry fruit surface without cell disruption.
- Association Bayberry knobs show exceptionally high expression of 13 acyl-lipid metabolism transcripts compared with leaves and other tissues.
- Observation Predicted protein sequences of the most highly expressed lipid-related transcripts in bayberry knobs are 100% identical to those in bayberry leaves.
- Mechanism Triacylglycerol biosynthesis and secretion in bayberry is achieved by both up and down-regulation of a small subset of cutin and saturated fatty acid genes.
- Mechanism Modifications in gene expression, rather than new gene functions, were the major mechanism by which bayberry evolved its specialized lipid metabolism.
