e0“The transfer of cultured tomato cells (Lycopersicon esculentum cv VFNT-Cherry) to a low water potential environment resulted in an increased dry weight to fresh weight ratio accompanied by a rapid accumulation of proline”
e6“Proline levels remained high after more than 100 cell generations in low water potential media, but declined rapidly after transfer to media with a less negative water potential”

Other claims from this paper (9)
- Intervention effect Transfer of cultured tomato cells to a low water potential environment increased their dry weight to fresh weight ratio.
- Intervention effect Transfer of cultured tomato cells to a low water potential environment rapidly increased proline accumulation.
- Association Proline content continued to increase during osmotic adjustment and growth of tomato cells, with a gain in turgor.
- Association The initial increase in proline concentration was accompanied by a drop in turgor in tomato cells.
- Association Proline accumulation depended more closely on cell osmotic potential than on cell water potential or initial turgor loss.
- Association The ultimate level of proline in tomato cells depended on the level of adaptation.
- Association Proline levels remained high in tomato cells after more than 100 cell generations in low water potential media.
- Intervention effect Addition of exogenous proline alleviated the inhibition of growth of tomato cells under water stress.
- Mechanism Proline accumulation is suggested to play a positive role in adaptation of tomato cells to changing external water potentials.
