TL;DR: This review is focused upon contemporary information on the changes in leaf structure, water relations and photosynthesis during acclimatization of plantlets to ex vitro conditions and some ways of improving plant survival and for the speeding up of acclimation.

TL;DR: A greater increase in cytokinin content in Pro transformants indicated a mild elevation of their stress tolerance, and bioactive cytokinins levels decreased in the whole plants, remaining relatively higher in preferentially protected upper leaves and in roots.

TL;DR: Modulation of cytokinin levels may positively affect plant responses to abiotic stress through a variety of physiological mechanisms, and is associated with enhanced stress tolerance of this genotype.

TL;DR: The substantial participation of SlIPT3 in CK metabolism during salt stress has been determined in 35S::SlipT3 tomato transformants, where enhancement of CKs accumulation significantly improved plant tolerance to salinity, underlining the importance of this phytohormone in stress response.

TL;DR: It is concluded that culture on sugar medium increases not only the photosynthetic potential but also the high light resistance of plantlets grown in vitro.
