- Intervention effect Constitutive expression of PvNCED1 increased ABA and phaseic acid levels in Nicotiana plumbaginifolia.
- Intervention effect After application of DEX, PvNCED1 message was transiently induced and ABA and PA accumulated in different lines.
- Observation The PA level continued to increase after ABA accumulation levelled off in the transgenic tobacco.
- Intervention effect In the presence of DEX, seeds of homozygous transgenic line TN1 showed a 4-day delay in germination.
- Intervention effect After DEX spraying, detached leaves of line TN1 had a drastic decrease in water loss relative to control leaves.
- Intervention effect Transgenic tobacco plants showed a marked increase in tolerance to drought stress.
- Mechanism Manipulating ABA levels in tobacco plants is possible by overexpressing the key regulatory gene of ABA biosynthesis.
- Mechanism Stress tolerance can be improved by increasing ABA levels.
