Title
Programmed Cell Death Occurs Asymmetrically during Abscission in Tomato

Other claims from this paper (7)
- Observation Programmed cell death hallmarks occurred in tomato leaf and flower abscission zones late in abscission.
- Observation The abscission zone showed cell viability loss, nuclear changes and DNA fragmentation.
- Observation Reactive oxygen species and enzymatic activities were elevated in abscission zones.
- Intervention effect Overexpression of antiapoptotic proteins delayed abscission.
- Observation PCD, LX and nuclease gene expression localized mainly to distal abscission-zone tissue.
- Observation Genes linked to cell wall hydrolysis and ethylene biosynthesis showed asymmetric expression.
- Mechanism The authors identify asymmetric PCD as a key abscission mechanism and propose a role for LX.
