Omics and Plant Abiotic Stress Tolerance

Abstract

Multiple biotic and abiotic environmental factors may constitute stresses that affect plant growth and yield in crop species. Advances in plant physiology, genetics, and molecular biology have greatly improved our understanding of plant responses to stresses. This book details on technologies that have emerged during the past decade and have been useful in studying the multigenicity of the plant abiotic stress response. Upstream molecular mechanisms are involved in the plant response to abiotic stress, above all in the regulation of timings and amount of specific stress responses. Post-transcriptional mechanisms based on alternative splicing and RNA processing, as well as RNA silencing define the actual transcriptome supporting the stress response. Beyond protein phosphorylation, other post-translational modifications like ubiquitination and sumoylation regulate the activation of pre-existing molecules to ensure a prompt response to stress factors. The text in this book deals with the importance of -omics approaches like Genomics, Metabolomics and Proteomics in abiotic stress tolerance. Large scale analytical approaches provide detailed information about the structure and complexity of signaling networks, identify subsets of genes or activities that are correlated to given stress factors and reveal unexpected or previously uncharacterized biochemical interactions. To the best of our knowledge no book on -Omics studies in relation to Plant Abiotic Stress Tolerance is available in the market. This book should therefore be a valuable asset for the readers.

A powerful framework for an integrative study with heterogeneous omics data: from univariate statistics to multi-block analysis

“…The interpretation can then lead to retro analyses to validate potential candidates. This can be done through new statistical analyses as well as new biological experiments (Chawla et al, 2011).…”

Plant Growth Promoting Microbes as Biofertilizers: Promising solutions for sustainable agriculture under climate change associated abiotic stresses

“…According to FAO (2007), only 3.5% of the global land area has not been affected by any environmental stress. Abiotic stresses hamper microbial functions and diversity, soil physicochemical properties and plant growth by affecting plant morphology, physiology and biochemistry through its gene regulation, thus, preventing plants from achieving their full genetic potential (6). The main abiotic stresses affecting plants are drought, salinity, extreme temperatures (high/low), acidic conditions, mineral deficiencies or toxicities, heavy metals, nutrient depletion and soil erosion (7).…”

Tiny Yet Indispensable Plant MicroRNAs Are Worth to Explore as Key Components for Combating Genotoxic Stresses

“…Plants are always subjected to various environmental stresses which cause severe DNA damage along with genotoxic stress, which in turn may reduce the development, genome stability, and crop productivity. Drought, extreme temperature stress, salt stress, oxidative stress, and damage due to UV irradiation are the abiotic stresses encountered by the plants on daily basis (Tuteja et al, 2011). Plants are also exposed to several biotic stresses through infection by bacteria, virus, pathogens, fungi, and insects (Huang et al, 2016).…”
