The changing climate conditions have led to an increase in extreme environmental cues, such as temperature fluctuations and droughts. Plants must induce defense responses against various abiotic stresses by integrating environmental signals with endogenous ones to produce optimal molecular and biological processes. Recently, extensive genetic and molecular biological studies have elucidated environmental signaling pathways, starting with the sensing of external environmental signals, followed by their transduction into internal signals, inducing highly correlated molecular responses, and ultimately resulting in changes in plant phenotype. Despite many studies extensively discussing the integration of naturally occurring environmental stress signals, the mechanisms underlying these interactions remain often unclear.

To understand plant growth under complex environmental stresses, it is crucial to improve our knowledge of how different signals are integrated into adaptive plant development. Cellular responsive pathways that govern the integration of abiotic signals are of particular interest. Recent advancements in omics approaches, including genomics, transcriptomics, proteomics, and metabolomics, have expanded our understanding of the molecular and cellular mechanisms involved in signal integration.

The goal of this Research Topic is to explore the diverse and complex ways that plants respond to various stressors, focusing on environmental cues-induced signaling networks, and adaptation mechanisms. We encourage studies that address the question of how plants integrate environmental signals through omics technologies or experimental biological approaches. We also welcome research on non-model species, especially grasses, when they further our understanding of the relationship between environmental signals and plant adaptation.

We welcome submissions of all article types accepted in Frontiers in Plant Science, addressing the following themes but are not limited to:

• Examining phenotypic changes in plant communities in response to environmental cues, including temperature fluctuations and drought.
• Exploring the physiological and biochemical mechanisms underlying plant responses to abiotic stresses.
• Utilizing multi-omics approaches to identify environmental signaling sensors in plants.
• Investigating molecules involved in the transduction of environmental signals into internal signals, such as phytohormones.
• Elucidating the roles of downstream key genes and their control and regulation mechanisms.
• Employing genome editing or transgenic approaches in plant breeding to enhance abiotic stress tolerance.
