Summary: The root system architecture of plants changes during salt stress exposure. Different accessions of Arabidopsis thaliana adopt different strategies in remodeling their root architecture during salt stress. Salt induces a multiphase growth response in roots, and both the growth rate of main roots during homoeostasis and lateral root appearance are the strongest determinants of overall root architecture. Furthermore, a trade-off between investing in main or lateral root length during salt stress is revealed. By studying natural variation in high-resolution temporal root growth using mathematical modeling, new insights in the interactions between dynamic root growth traits are discovered.

Summary: Sound waves have a significant impact on the growth of Arabidopsis, resulting in increased root length and cell number in the root apical meristem. Genes related to cell division are upregulated in seeds exposed to sound waves. The concentrations of cytokinin and auxin in the roots of plants change after exposure to sound waves.

Summary: The study reveals that the plant hormone CK plays a crucial role in the assembly of the plant microbiome, increasing richness and promoting the presence of Firmicutes. CK-mediated immunity partially depends on the microbial community, and bacilli isolated from CK-rich plant genotypes induce plant immunity and enhance disease resistance. The leaf microstructure derived from CK-rich plant genotypes supports the growth of bacilli in a biomimetic system, indicating that CK can promote the growth and biofilm formation of immune-inducing bacilli isolates.

Summary: Bamboo differentiates between a cell division zone and a cell elongation zone during rapid growth. The cell wall and organelles such as chloroplasts are more developed in the cell elongation zone, while hydrogen peroxide and stomata are concentrated in this zone. Hormone levels, including gibberellin, auxin, cytokinin, and brassinosteroid, are higher in the cell division zone, whereas salicylic acid and jasmonic acid levels are higher in the cell elongation zone. Transcriptome analysis reveals differential gene expression, with cell division and primary metabolism genes being upregulated in the cell division zone, and photosynthesis, cell wall growth, and secondary metabolism genes being significantly upregulated in the cell elongation zone. Overexpression of the transcription factor BmMYB83 promotes cell wall lignification.

Summary: The rhizosphere is a soil-plant interface where bacterial and fungal species colonize and provide growth-promoting and adaptive benefits. Plant-bacteria relationships rely on the perception of volatile organic compounds (VOCs), phytohormones, and bacterial quorum sensing signals. Beneficial Trichoderma fungi emit active VOCs that contribute to plant morphogenesis and affect their colonization on roots. Recent findings have shed light on how compounds from beneficial bacteria and fungi impact root architecture and the signaling events mediating microbial recognition.

Summary: The root is a crucial organ for plants, impacting their growth and development. Cytokinins, a classic phytohormone, are primarily synthesized in plant root tips and influence root growth and development through signal transduction pathways. Additionally, cytokinins play a significant role in abiotic stress response.

Summary: Roots are able to sense and respond to elevated temperature independently of shoot-derived signals. This response is mediated by an unknown root thermosensor that uses auxin as a messenger to relay temperature signals to the cell cycle. Growth promotion is primarily achieved by increasing cell division rates in the root apical meristem, dependent on de novo local auxin biosynthesis and temperature-sensitive organization of the polar auxin transport system.

Summary: Plant organogenesis requires the matching of metabolic resources with developmental programs. The root system in Arabidopsis is determined by primary root-derived lateral roots (LRs) and adventitious roots (ARs) formed from non-root organs. Lateral root formation requires the activation of transcription factors ARF7, ARF19, and LBD16. Adventitious root formation relies on the activation of LBD16 by auxin and WOX11. The allocation of shoot-derived sugar to the roots affects branching, but the mechanism of LRs formation is still unknown.

Summary: Plants use electrical and chemical signals for systemic communication, with herbivory triggering glutamate accumulation and calcium waves to report damage and initiate defense. By expressing fluorescent glutamate sensors in Arabidopsis, researchers found that displaying the sensors externally impacted plant growth and development. The study also revealed that sequestering glutamate at the cell surface disrupts meristematic cell supply and localized signaling, affecting root growth.

Summary: Microbes have an influence on the growth and adaptability of plants, but the microbiomes associated with rare and endemic plants have not been fully explored. This study investigated the bacterial community structure of an endemic plant in Korea and found that the root bacterial community structure differed from that of the soil and rhizosphere. The diversity of endogenous bacteria in cultivated plants was lower than in wild plants, but certain bacterial species were shared. The study also identified certain microbial strains that promoted growth and salt stress resistance in Arabidopsis and chive.

Summary: The utilization of silver nanoparticles (AgNPs) has become widespread due to their superior properties, but this also poses the risk of irreversible environmental contamination. Plant cuticle and cell wall provide protection to internal cell structures, such as the cytoskeleton, which reacts quickly to threats and triggers defense signaling. This study found that the number and growth rate of microtubules (MTs) decreased significantly after AgNPs treatment, and the levels of stress phytohormone derivatives increased. These findings contribute to understanding the response mechanism to AgNPs and the broader physiological context of MT structure and dynamics.

Summary: Cells sense extracellular signals and regulate their metabolism and physiology accordingly. The plasma membrane plays a crucial role in this process by acting as an informational barrier and responding to regulatory inputs. Phosphatidic acid (PA) is a well-known intracellular messenger that regulates various cellular processes and is involved in plant growth, development, and stress tolerance. This review focuses on the primary signaling events triggered by rapid PA accumulation in plant cells, and discusses its role in mediating the response to hormones and hormone-like regulators.

Summary: This study explores the possibility of firmly anchoring silver nanoparticles (AgNPs) into polyetherether ketone (PEEK) with a tailored surface morphology that exhibits laser-induced periodic surface structures (LIPSS). The antibacterial test proved that AgNPs-decorated LIPSS represents a more effective bactericidal protection than their planar counterparts, even if they contain a lower concentration of immobilized particles. Nanostructured PEEK with embedded AgNPs may open up new possibilities in the production of templates for replication processes in the construction of functional bactericidal biopolymers or may be directly used in tissue engineering applications.

Summary: Ultramicrotome cutting is a useful tool for preparing thin polymeric films, allowing for decreased surface roughness and the recording of morphological changes during processing. In this study, PET and PEEK polymers were modified using a KrF excimer laser and decorated with AgNPs. The laser irradiation resulted in ripple-like structures on PET and worm-like structures on PEEK, both covered by AgNPs. The technique shows potential for direct polymer writing and the preparation of stimuli-responsive nanoporous membranes.

Summary: This work describes the preparation of fibers array with electric field switchable wettability using the piezoelectric properties of PVDF and the chemical reactivity of PMMA. It was found that by varying the orientation of the electric field and using different substrates with different conductivity, the shape of the deionized water drop can be controlled effectively. Additionally, the polarity of water can be shifted by dissolving NaCl salt in different concentrations.
