Summary: Plant endoplasmic reticulum (ER) remodelling is important for targeted protein secretion, organelle interaction, and signal exchange, regulated by actin cytoskeleton and microtubule-based machinery. The dependence on cell type and developmental stages for ER dynamics in plants is highlighted in recent discoveries. The ER membrane also plays a role in organizing the cytoskeletal network, impacting cytoskeleton structure.

Summary: This review summarizes recent advances in the role of plant cytoskeleton and associated proteins in abiotic stress management. Plants have evolved specific mechanisms to sense external stress and transmit information for appropriate responses. The plant cytoskeleton, along with associated proteins, not only plays a role in cell growth and proliferation but also functions in stress response and resilience.

Summary: DELLA proteins participate in ovule initiation by forming a protein complex with the CUC2 transcription factor. This interaction helps determine the boundary regions between ovules during pistil development. DELLA proteins may also act as transcriptional co-regulators in a CUC2-dependent manner at certain gene loci.

Summary: This study investigates the crosstalk between GA and UV-B signaling pathways in UV-B-induced photomorphogenesis. It is found that DELLA acts as a positive regulator in UV-B-induced photomorphogenesis. Additionally, the HY5-BBX24-DELLA module is identified as an important signal regulating network.

Summary: Living organisms are constantly exposed to mechanical forces, which regulate key cellular processes in both animal and plant development. Plant cells experience various mechanical stresses, and cortical microtubules (CMTs) in plant cells are influenced by these stresses. CMTs can reorient in response to mechanical stresses and align with the direction of maximal tensile stress. This review discusses the regulation of CMTs by mechanical stresses, the molecules and pathways involved, available techniques for mechanical perturbation, and unanswered questions in this field.

Summary: This study reports that microtubules can physically couple motor movement in the absence of detectable short-range interactions. The long-range microtubule-mediated coupling mechanism may affect the binding kinetics and mechanochemistry of motors, providing new forms of collective motor behavior.

Summary: The plant hormone gibberellin (GA) has different effects on floral development and plant height in maize tassels depending on the developmental context. The study reveals the role of GA signaling and repression in regulating floral development in the presence and absence of excess GA. The study also shows that genotype affects all GA-regulated phenotypes, but there is no correlation between these phenotypes, indicating the complexity of the relationship between GA and development.

Summary: The GAF1 transcription factor binds to the GA20ox1 promoter in Arabidopsis, along with DELLA protein, to promote GA20ox1 expression and contribute to feedback regulation and tissue specificity. Gibberellins play a key role in plant growth and development, controlled by endogenous GA levels and DELLAs as negative regulators of GA signaling. The study identified GAF1 as a coactivator with DELLAs and revealed its involvement in feedback regulation and tissue-specific expression of GA biosynthetic genes.

Summary: The mammalian cytoskeleton plays an important role in transmitting external forces to the cell interior and generating intracellular forces. The three interpenetrating structural proteins, actin, microtubules, and intermediate filaments, have interdependent functions and the intermediate filaments play a central role in mechanosensitivity. Cytoskeletal crosstalk regulates the stability and organization of all three filament families at different scales, and also affects cell adaptation to external cues.

Summary: This study identified 10 BnaDELLA genes in rapeseed, highlighting their evolutionary characteristics, genomic structure, miRNA targets, and expression patterns. The findings suggest that modulating individual BnaDELLA expression could enhance rapeseed stress tolerance and harvest index, providing valuable insights for further research in this area.

Summary: The study revealed that HAT1 negatively regulates GA-mediated trichome initiation and cotyledon expansion, interacts with DELLAs, and forms a regulatory negative feedback loop to control GA homeostasis for fine-tuning trichome development and cotyledon expansion. This provides insight into a novel mechanism by which the plant regulates trichome initiation and cotyledon growth under different GA concentrations.

Summary: Salt stress has distinct effects on the root xylem development of Arabidopsis seedlings, leading to the formation of protoxylem gaps. The extent of protoxylem gaps positively correlates with salt tolerance. Reduced gibberellin signaling and the involvement of various genes are required for the formation of protoxylem gaps. These findings provide important insights into the acclimation of plants to high salt conditions.

Summary: The specialized structure and function of neurons rely on the organization of the cytoskeleton and the transport system of mitochondria. Mitochondria provide energy and calcium buffering in neurons, and their distribution is regulated by a dynamic balance between active transport and stable docking. This review summarizes the mechanisms of selective mitochondrial transport in different neuronal compartments and the potential for intercellular transfer, which has promising implications in disease treatment.
