Dissecting the roles of osmolyte accumulation during stress
In re-assessing the functional significance of compatible solute accumulation, it is suggested that proline and glycine betaine synthesis may buffer cellular redox potential and contribute to stress-tolerant phenotypes observed.
Somaclonal variation in plants: causes and detection methods
The possible causes, detection methods and desirability of variants are summarized, and examples of some useful variants generated as a result of somaclonal variation are outlined.
Isolation of the major germination cue from plant-derived smoke
Smoke as a germination cue
Smoke may well be the overriding trigger for germination in relation to specific growth habits, regeneration strategies, seed storage, seed sizes, dispersal modes and structures for a large number of species growing in fire-prone habitats.

The results support the possible use of topolins as an alternative to BA for Cavendish banana tissue culture and requires a more stringent investigation as the results obtained in this investigation could have been influenced by carry-over effects from the initial cultures.
Solving the problem of shoot-tip necrosis in Harpagophytum procumbens by changing the cytokinin types, calcium and boron concentrations in the medium
Optimizing the micropropagation protocol for the endangered Aloe polyphylla: can meta-topolin and its derivatives serve as replacement for benzyladenine and zeatin?
In vitro grown Aloe polyphylla and its derivatives were cultured on full strength Murashige and Skoog basal medium with different concentrations of cytokinins and solidified with 1% Bacteriological Agar and mT was the preferred cytokinin both in terms of multiplication rate and rooting.
Factors contributing to in vitro shoot-tip necrosis and their physiological interactions
This review article summarizes the literature published on the causes of in vitro STN in plants such as medium type, plant growth regulators, calcium, boron, medium additives, the culture environment, their interaction and physiological effects.
