TL;DR: 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.

TL;DR: A critical evaluation of some common in vitro antioxidant capacity methods is provided and a discussion on the role and controversies surrounding non-enzymatic biomolecules, in particular phenolic compounds and non-phenolic compounds, in oxidative processes are discussed in an attempt of stemming the tidal wave that is threatening to swamp the concept of natural antioxidants.

TL;DR: Ethnobotanical information on plants used by the traditional healers in South Africa to treat mental illnesses, specifically epilepsy, depression, age-related dementia and debilitative mental disorders is presented.

TL;DR: 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.

TL;DR: How advanced chemical, biotechnological and computational molecular biology methods can be used for robust exploitation of bioactive compounds from these microorganisms is focused on.
