Other claims from this paper (6)
- Observation Wax is secreted to the fruit surface without cell disruption.
- Association Bayberry knobs show exceptionally high expression of 13 acyl-lipid metabolism transcripts compared with Bayberry leaves and other tissues.
- Association Fatty acid oxidases and desaturases are down-regulated in Bayberry knobs compared with the comparison tissues.
- Association Predicted protein sequences of the most highly expressed lipid-related enzyme transcripts in Bayberry knobs are 100% identical to those from Bayberry leaves.
- Mechanism TAG biosynthesis and secretion in Bayberry is achieved by up and down-regulation of a small subset of cutin and saturated fatty acid biosynthesis genes.
- Mechanism Gene expression modifications, not new gene functions, were the main mechanism of Bayberry specialized lipid metabolism evolution.
