Summary: This study revealed that the responses in roots, rather than in shoots, were crucial for greater salt tolerance in quinoa accessions with low epidermal bladder cell (EBC) density. The tolerant accession showed improved root plasma membrane integrity and ion retention in response to salt, along with faster and root-specific oxidative stress responses within 30 minutes of salt application. This demonstrated that differential root signaling events are essential for halophytic quinoa adaptation to salinity, independent of salt sequestration in EBCs.

Summary: Stress granule formation is a complex process that disrupts cellular metabolism in response to stressors, with different chemical stressors leading to compositionally distinct stress granules. Osmotic stress induced by sorbitol does not require the common stress granule components G3BP1/2, and leads to significant depletion of nuclear polyadenylated RNA. Additionally, this stress causes shifts in RNA-binding protein localization and function.

Summary: Plants have highly compartmentalized eukaryotic cells, with plastids and mitochondria relying on the flow of information to and from the nuclei. Retrograde and anterograde signals, such as the retrograde signaling molecule PAP, play a role in coordinating intracellular functions in response to biotic and abiotic stresses. The SAL1 protein, which dephosphorylates PAP to AMP, has different stability and impacts in different cell compartments. Further research is needed to understand the role of the SAL1-PAP pathway in various cellular processes under stress conditions.

Summary: Reactive electrophilic species are widely present in plant cells and play a role in specific redox-regulated signaling events. Redox signaling is known to regulate gene expression during various biological processes, including plant growth, development, and stress responses. Recent data has shown that transcription factors are a major target of cysteine thiol-based oxidative post-translational modifications, which can affect their activity and transmit redox information to the nucleus. This review discusses the progress made in characterizing these modifications, their biochemical properties, and their effects on plant transcription factors, as well as the underlying mechanism of redox regulation and the challenges that remain in understanding the redox regulation of plant gene expression.

Summary: The cell cycle inhibitor SIAMESE-RELATED1 (SMR1) is identified as a crucial factor in determining the ratio of pavement cells to stomata in response to drought. It terminates the self-renewal potential of stomatal lineage ground cells (SLGCs) and promotes the differentiation of SLGCs into pavement cells. By controlling the differentiation of SLGCs, SMR1 plays a significant role in adjusting the development of the leaf epidermis to suit environmental conditions. As a result, SMR1 is proposed as a promising target for developing climate-resilient plants.
