چکیده
Introduction: Abiotic limitations, like water deficit, high temperature, salinity, and cold are some of the main barrier agents to plant growth throughout the world. To obtain a comprehensive view of a plant’s response to abiotic stresses, we applied robust bioinformatics approaches including the integration of meta-analysis, weighted gene co-expression network analysis (WGCNA), and machine learning.Materials and Methods: In this paper, ۳۲ samples from four different stresses were chosen for analysis. Cross-platform combination method was used to conduct meta-analysis. To find gene co-expression modules related to stress conditions WGCNA analysis was performed. Machine learning methods were applied to validate the most important hub genes.Results: Meta-analysis detected ۲۷۵ differential expression genes (DEGs) and WGCNA showed ۲۸ distinct modules under those stresses. Seven potential hub genes (At۱g۰۷۴۳۰ (HAI۲), At۵g۵۲۳۰۰ (LTI۶۵), At۱g۶۰۱۹۰ (PUB۱۹), At۵g۵۰۳۶۰, At۱g۷۷۱۲۰ (ADH۱), At۱g۵۶۶۰۰ (GolS۲), and At۵g۵۷۰۵۰ were detected by network analysis and validated by machine learning methods. These genes are involved in different pathways of cellular response to abiotic stresses.Conclusions: Analysis indicates that among the hub genes, At۵g۵۰۳۶۰ was identified as a novel candidate gene. As such, the At۵g۵۰۳۶۰ can be used in plant breeding programs for the development of abiotic stress-tolerant crops.کلیدواژه ها
