Effect of Climate Change on Abiotic Stress Response Gene Networks in Arabidopsis thaliana

Abstract

Climate change leads to various abiotic stresses that the plants face within their life cycles. This leads to extensive biochemical, physiological, and morphological changes in plants. Plants have evolved several defense mechanisms to survive in abiotic stress conditions, and all of these mechanisms include the differential expression of hundreds of genes involved in tens of different biological pathways. Recent systems biology approaches have identified a core gene network that is essential in abiotic stress tolerance in plants. However, a more detailed analysis is required to understand the core transcriptional regulatory network of stress-responsive genes in the model plant Arabidopsis thaliana. Here we explain the identification of a core transcriptional regulatory network of stress-responsive genes in Arabidopsis by bioinformatic analyses under several abiotic stress conditions. Then, known functions of identified transcription factor families are discussed in detail. © The Author(s), under exclusive license to Springer Nature Switzerland AG 2022. All rights reseverd.
