This§book is the first of its kind to highlight the positive impact of natural UV§radiation on plants through unique adaptations in various metabolic pathways, and§provides an evolutionary sketch of the development of molecular mechanisms for§protecting plants from solar UV ever since their migration to terrestrial§habitats. Experimental evidence is provided for establishing how plants, through§their stationary habit in the open field, survive and flourish by developing suitable§UV acclimation strategies through the repair of damaged macromolecules and/or§upregulation of screening compounds viz. flavonoids. Presenting an analysis of related§literature, it also highlights the importance of outdoor experiments over those§in closed chamber under artificial UV light for obtaining realistic data.§§The book presents a comprehensive§account of the stratospheric ozone layer, its formation and seasonal thinning,§with particular reference to alarming anthropogenic destruction of the ozone§layer since the last quarter of the twentieth century, which has resulted in increased§UV fluence on Earth. It discusses variations in the hazardous impact of UV on§life at different latitudes through the ages, and examines altitudinal variations§in UV effects in case studies demonstrating high antioxidant content and aroma§status in Darjeeling tea leaves (at high altitudes) compared with those of the same§tea clones in Assam leaves (at low altitudes), with both sites being at the same§latitude. It provides evidence which suggests that the UV effects relating to§the expression of seed vigour-viability could be epigenetic.§§Further, it presents recently developed microscopic§technologies for demonstrating the penetration of UV into plant cells, and discusses§how cellular metabolism can be affected either directly or via signal§transduction. Effect of damage in DNA (the key target of UV radiation) has been§demonstrated and estimated using precise techniques. The latest "FOX Hunting"§technique as a useful means of transcriptome analysis that may be used for§developing UV tolerant plants through Marker Assisted Breeding has also been§discussed. Using biochemical and biotechnological methods, the experiments§presented highlight the gene X environment based upregulation of specific§metabolic pathways, allowing i) value addition in plant-derived food, and ii) paving§the way for the industrial manufacture of Alternative Medicine products. The§book is enriched by a critical review of the available literature and§appropriate case studies selected from the author's own findings, which span nearly§four decades of active research.§§
