Other claims from this paper (8)
- Observation The petals contained 131 identified VOCs, dominated by terpenoids, alcohols and esters.
- Observation Twelve key aroma-active compounds defined a floral, fruity and fresh fatty volatile profile.
- Observation Transcriptomic analysis found 15,189 differentially expressed genes enriched in pathways related to terpenoids, phenylpropanoids and fatty acid derivatives.
- Association DXS / FPPS / TPS structural gene modules correlated temporally with corresponding terpenoid volatiles.
- Association PAL / 4CL / CAD structural gene modules correlated temporally with corresponding phenylpropanoid volatiles.
- Association LOX / ADH / AAT structural gene modules correlated temporally with corresponding fatty acid derivative volatiles.
- Association Among 2,547 predicted transcription factors, 58 candidate regulators were closely associated with 12 key volatiles.
- Observation Terpenoids and phenylpropanoids dominated floral scent at full bloom.
