Abstract: The nucleolus is a key structure in the nucleus of eukaryotic cells. Ribosome biogenesis initially takes place in the nucleolus, which involves a series of complex reactions and requires the participation of many nucleolus-associated factors. Abnormal ribosome biogenesis usually leads to disordered nucleolus structure, cell cycle arrest, cell senescence, and even cell death. The mechanism of ribosomal stress response has been studied well in mammals, while it remains largely unknown in plant cells. Nevertheless, it has been found that members of the plant-specific NAC transcription factor family are involved in various intracellular stress responses, including ribosomal stress, in plant cells. In addition, we previously reported a coordination mechanism between auxin system and ribosome biogenesis for modulating plant development. In this review, we discussed potential mechanisms of ribosome stress response in plant cells through combining the knowledge of ribosomal stress response pathways in mammals.
