This book extensively covers the various forms of abiotic stresses encountered in plants and the susceptibility or tolerance mechanism to diverse stresses in different plant species. The focus of the stress response is at the morphological, anatomical, biochemical, molecular and gene expression levels. Moreover, transgenic approaches in overcoming stress tolerance have been attempted in recent years in several plant species. This book compiles these studies and provides researchers and scientists with a more logical approach. The book enables plant scientists to unravel the different pathways and signaling cascades involved in stress response, allowing the generation of stress tolerant plants either through breeding or genetic engineering approaches.
