Driving Forces of Evolution

<p>To cope with the abiotic stress-induced osmotic problems plants adapt by either increasing uptake of inorganic ions from the external solution or by de novo synthesis of organic compatible solutes acting as osmolytes. Of the osmoregulants and protectants discussed in this volume trehalose fructans ectoine and citrulline which are generated in different species in osmotically ineffective amounts mitigate the stress effects on cells/plants and improve productivity. There are several pieces of encouraging research discussed in this volume showing significant improvement in stress tolerance and in turn productivity by involving genetic engineering techniques.</p>
