The processing body (P-Body) is a membrane-less organelle with stress-resistant functions. Under stress conditions, cells preferentially translate mRNA that favors the stress response, resulting in a large number of transcripts unfavorable to the stress response in the cytoplasm. These non-translating mRNAs aggregate with specific proteins to form P-Bodies, where they are either stored or degraded. The protein composition of P-Bodies varies depending on cell type, developmental stage, and external environmental conditions. This review primarily elucidates the protein composition in plants and the assembly of P-Bodies, and focuses on the mechanisms by which various proteins within the P-Bodies of plants regulate mRNA decapping, degradation, translational repression, and storage at the post-transcriptional level in response to ethylene signaling and abiotic stresses such as drought, high salinity, or extreme temperatures. This overview provides insights into the role of the P-Body in plant abiotic stress responses.
