Inter-organellar communication is a fundamental mechanism for translating various stimuli into acclimatory responses, enabling cells to ensure optimal growth and survival under environmental stress conditions. This communication often involves structural and morphological modifications of individual organelles. For instance, chloroplasts extend stroma-filled tubular structures known as stromules, which associate with the nucleus, the endoplasmic reticulum (ER), and the plasma membrane. Similarly, mitochondria and ER contact has been observed under abiotic stress conditions. These dynamic morphological and positional changes of organelles facilitate communication, allowing the transfer of signaling molecules and physiological components to maintain homeostasis and protect against biotic and abiotic threats at the organelle level. Plant physiological factors, such as reactive oxygen species and calcium gradients, may contribute to these communications.

In this Research Topic, we aim to collect research and review articles addressing organelle dynamics and interactions with other subcellular compartments during plant responses to environmental stresses, including both biotic and abiotic stressors. The goal of this special collection is to enhance understanding of complex cellular responses, with a particular focus on—but not limited to—the interaction of multiple subcellular compartments as they perceive and respond to environmental stresses. Studies that use multidisciplinary approaches to characterize the role of inter-organellar communication are strongly encouraged. This collection also highlights studies connecting organelle communications and cell physiology with plant organismal responses to environmental stresses.

We invite researchers to submit original research articles, reviews, and short communications covering, but not limited to, the following topics:

- Microscopy: Examining organelle dynamics and communication in connection with spatio-temporal physiological changes in cells

- Genomic and genetic studies: Uncovering novel genes involved in organelle dynamics

- Single-cell or bulk transcriptomic analyses: Elucidating gene expression patterns and regulatory networks that connect stress responses with organelle dynamics and communication

- Proteomic profiling: Identifying protein complexes that control organelle communication and stress response signal transduction

- Integrative multi-omics approaches: Providing a comprehensive understanding of plant cell physiology and organelle communication in stress responses through the integration of multiple omics datasets

- Computational tools and methodologies: Developing and applying innovative tools for dissecting organelle dynamics, such as improved methodologies for imaging analysis and enhanced analytical tools for omics data
