Postharvest application of the strigolactone analog GR24 enhances antioxidant capacity and delays senescence in cut roses (Rosa hybrida) with Transcriptomic evidence for the involvement of phenylpropanoid biosynthesis genes.
- Open access
Exogenous application of the strigolactone analog GR24 extends vase life of cut roses by 4 days and enhances antioxidant capacity through activation of phenylpropanoid biosynthesis genes.
- Why it matters: Short vase life limits the commercial value of cut roses, and understanding how to delay senescence could improve postharvest quality and longevity.
- What they did: Researchers applied 1 μM GR24 to cut roses and used physiological assessments alongside transcriptomic sequencing to identify key genes and pathways involved in senescence delay.
- The result: GR24 reduced water loss, membrane damage, and oxidative stress, while upregulating phenylpropanoid biosynthesis genes, providing molecular targets for improving cut flower preservation.
