Retention of RNA in the nucleus precisely regulates the time and rate of translation and controls transcriptional bursts that can generate profound variability in mRNA levels among identical cells in tissues. In this study, we investigated the function of Cajal bodies (CBs) in RNA retention in leaf nuclei during hypoxia stress was investigated. It was observed that in mutants with a complete absence of CBs, the accumulation of poly(A) RNA in the leaf nuclei was lower than that in wt under stress.

- The study investigates the role of microRNAs (miRNAs) in the dedifferentiation of mesophyll cells in Arabidopsis thaliana, particularly after enzymatic removal of cell walls, focusing on protoplasts and cells derived from protoplasts (CDPs).
- Findings reveal a significant decrease of AGO1 protein and dicing bodies in protoplasts, while CDPs show an increase, indicating changes in miRNA activity during the dedifferentiation process.
- Conclusively, miRNAs play a more important role in the later stages of dedifferentiation and cell division, influencing processes like organogenesis and stress responses, with defective miRNA biogenesis linked to decreased cell
Hypoxia in plants is a usually the result of heavy rainfall and the subsequent flooding. All current climate models indicate a notable increase in extreme weather over the coming years. Depending on the species and geographical location, plants have developed two distinct strategies for hypoxia stress adaptation: escape and quiescence.
