Abstract
Plant abiotic stress responses are vital yield-restricting aspect in agriculture. Recent technology in plant biology allows research of such stress responses at a molecular scale in plants. Network analysis provides in-depth knowledge regarding omics information visualisation as it reduces the intrinsic intricacy of such data. The use of integrated functional genomics helps to understand the relationship between the genomic profile and the phenotypic profile in different environmental conditions of an organism. Plants’ responses to abiotic stress are often considered as a complex process. Systems biology approaches allow visualising and understanding how plant life works to overcome abiotic stress. The combination of integrated functional genomics along with bioinformatics will put a hand in additional in-depth research knowledge on stress tolerance to plants by exploiting available genetic information and continuously improving techniques and strategies. Most of the omics technologies are high throughput with very rapid data generation rates and humongous outputs. These technologies have made noticeable contributions to the modern-day improvements in our knowledge of plant biology. So, in this review, omics studies and the system biology approach towards abiotic stress tolerance in plants are highlighted.
Highlights
A unit of self-sustaining but interconnected components that function together as a unified whole is referred to as a system [1]
The last decade has witnessed an increase in the knowledge and research in the systems biology science, which integrates the humongous data generated from the genomic technologies, projects computational models thereby helping us to figure out the topology, dynamical functions of the molecular systems sustaining an organism [2]
In A. thaliana, an investigation was undertaken to study the translational regulation under control and sublethal hypoxia stress conditions by precise mapping of ribosome footprints (RFs) on mRNAs, the results showed that there was nearly 100-fold variation in the efficiency of translation of the mRNAs under each condition
Summary
A unit of self-sustaining but interconnected components that function together as a unified whole is referred to as a system [1]. Duplication events at the genome level in the past have led to the diversification of duplicated genes and pathways Even such events and their analysis are not simple as they are complicated and the variable environment will elicit complex responses resulting from a different group of pathways and their components. This is affected by the growth stage and the nutritional status of the system involved. In this review, the different omics approach towards abiotic stress response in plants is elaborated along with the integrated system biological approaches which will help to understand the perspective towards abiotic stress response in plants
