Other claims from this paper (12)
- Observation Potato encodes at least seven AKIP1-like RNA-binding proteins.
- Observation StUBA2a/b and StUBA2c are homologous to VfAKIP1 and Arabidopsis UBA2s.
- Mechanism The first RRM domain was crucial for the cell death phenotype.
- Intervention effect Constitutive StUBA2a/b expression did not cause young-seedling growth arrest or lethality in Arabidopsis.
- Intervention effect Constitutive StUBA2a/b expression induced early leaf senescence in Arabidopsis.
- Association Early senescence was associated with increased expression of defence and senescence genes.
- Observation The phenotype worsened upon flowering and shortened the life cycle.
- Intervention effect Darkness enhanced leaf senescence of StUBA2a/b Arabidopsis plants.
- Association Senescence was accompanied by H2O2 accumulation and altered autophagy gene expression.
- Observation Salicylic acid signalling and biosynthetic genes were upregulated in StUBA2a/b plants.
- Observation GFP-tagged StUBA2 proteins localized to nuclear speckles.
- Recommendation Authors propose StUBA2s for inducing potato shoot senescence at harvest.
