Other claims from this paper (13)
- Observation A stay-green rice mutant was isolated by irradiation.
- Observation The mutant retained chlorophyll, chlorophyll-protein complexes and thylakoid structures.
- Observation The mutant lost photosynthetic competence during senescence.
- Observation SGR was cloned and encoded a protein with a putative chloroplast transit peptide.
- Observation SGR protein occurred in soluble and thylakoid membranes.
- Observation SGR and PaO were constitutively expressed and upregulated in dark-induced senescence.
- Intervention effect ABA enhanced senescence-induced expression of SGR and PaO.
- Intervention effect SGR overexpression reduced grana thylakoid lamellae.
- Intervention effect SGR overexpression reduced chlorophyll content in normal leaves.
- Observation A small amount of chlorophyllide a accumulated in mutant leaves.
- Observation Chlorophyllide a also accumulated in wild-type rice leaves during senescence.
- Observation Pheophorbide a was detected in sgr leaves in darkness.
- Mechanism The authors proposed that SGR may affect PaO activity and chlorophyll breakdown.
