Abiotic stresses such as drought (water deficit) extreme temperatures (cold frost and heat)
salinity (sodicity) and mineral (metal and metalloid) toxicity limit productivity of crop
plants worldwide and are big threats to global food security. With worsening climate change
scenarios these stresses will further increase in intensity and frequency. Improving tolerance
to abiotic stresses therefore has become a major objective in crop breeding programs. A lot
of research has been conducted on the regulatory mechanisms signaling pathways governing these
abiotic stresses and cross talk among them in various model and non-model species. Also
various 'omics' platforms have been utilized to unravel the candidate genes underpinning
various abiotic stresses which have increased our understanding of the tolerance mechanisms at
structural physiological transcriptional and molecular level. Further a wealth of
information has been generated on the role of chromatin assembly and its remodeling under
stress and on the epigenetic dynamics via histones modifications.The book consolidates outlooks
perspectives and updates on the research conducted by scientists in the abovementioned areas.
The information covered in this book will therefore interest workers in all areas of plant
sciences. The results presented on multiple crops will be useful to scientists in building
strategies to counter these stresses in plants. In addition students who are beginners in the
areas of abiotic stress tolerance will find this book handy to clear their concepts and to get
an update on the research conducted in various crops at one place
