Other claims from this paper (15)
- Observation Three-day-old wheat coleoptiles were desiccation tolerant while roots were not.
- Intervention effect Cutting coleoptiles before dehydration increased drying rate.
- Intervention effect Cutting coleoptiles before dehydration made them desiccation sensitive.
- Observation Sensitive tissues accumulated H(2)O(2) and MDA after dehydration.
- Observation Dry sensitive wheat tissues showed substantial subcellular damage.
- Observation Dry tolerant coleoptiles accumulated H(2)O(2) and MDA only slightly.
- Observation No subcellular damage was evident in dry tolerant coleoptiles.
- Observation Glutathione reductase, superoxide dismutase and catalase activities rose on drying in both sensitive and tolerant tissues.
- Observation Antioxidant enzyme activity persisted after rehydration only in tolerant tissues.
- Observation Three LEA- and dehydrin-like proteins were detected in tolerant coleoptiles dried to 3.0 g.g or below.
- Observation Only Asp 52 was induced at low water content in rapidly dried sensitive coleoptiles.
- Observation XV8 RNA was induced by drying only in tolerant coleoptiles and correlated with protein expression.
- Observation Sucrose accumulation during dehydration was similar in sensitive and tolerant tissues.
- Mechanism Authors infer that rapid drying overwhelms antioxidant protection and causes lethal damage.
- Mechanism Authors infer slow drying permits antioxidant detoxification and desiccation tolerance.
