Other claims from this paper (10)
- Observation Abscisic acid content is elevated in abscised plum fruits.
- Observation The critical abscission period is 24 days after flowering, characterized by ovule abortion and abscission zone formation.
- Observation Integrated transcriptomic and metabolomic analyses highlight a central role of hormone signalling pathways in plum fruit abscission.
- Observation PsGA2ox1 is highly up-regulated in abscised plum fruits.
- Association PsGA2ox1 shows strong negative correlations with bioactive GA and JA levels.
- Intervention effect PsGA2ox1 overexpression reduces GA3 levels in plum.
- Intervention effect PsGA2ox1 overexpression induces the expression of key abscission-related genes in plum.
- Intervention effect Silencing of PsGA2ox1 has the opposite effects to its overexpression in plum.
- Mechanism PsGA2ox1-mediated GA inactivation modulates hormonal balance and transcriptional reprogramming, involving cell wall remodelling, during early fruit abscission in plum.
- Recommendation PsGA2ox1 is identified as a potential target for improving fruit set in plum.
