Other claims from this paper (9)
- Intervention effect Relative water content fell after 48 and 72 hours of PEG exposure.
- Intervention effect Electrolyte leakage increased under osmotic dehydration.
- Intervention effect Chlorophyll a and b contents decreased under osmotic dehydration.
- Intervention effect Photosystem 2 activity was inhibited under osmotic dehydration.
- Intervention effect Progressive water stress reduced psbA, psbD and cab transcripts.
- Intervention effect Major PS 2 protein contents declined with increasing water stress.
- Observation Miannong No. 5 had less plasma membrane destruction than Miannong No. 4.
- Mechanism The authors attribute cultivar differences in LHC 2 proteins to cab transcript levels.
- Mechanism The authors infer that LHC 2 proteins protect the PS 2 reaction centre.
