Summary: The transmission of seed-borne pathogens during seed germination is a major cause of crop diseases. However, the immune responses of germinating seeds to biotic invaders are poorly understood. This study used the Arabidopsis thaliana/Alternaria brassicicola patho-system to investigate the transcriptional responses of germinating seeds and young seedlings to infection by the necrotrophic fungus. The results revealed non-canonical immune responses in early germinating seeds compared to early seedling establishment stages.

Summary: Melatonin serves as an important bioactive molecule in plants and enhances plant resistance to Botrytis cinerea infection. Increased melatonin content activates resistance genes and defense pathways, leading to reduced disease symptoms and lesion size. Furthermore, melatonin plays a crucial role in regulating plant stress resistance at the genetic level.

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: Seed dormancy is a complex trait controlled by genetic and environmental factors, and it is affected by nitrate and AtAAH. Nitrate reduces seed dormancy, while AtAAH and other genes are up-regulated in dormant seeds. Ataah mutant seeds have higher dormancy and accumulate high levels of uric acid, allantoin, and urea.

Summary: Overexpression of MTP8 significantly increases Mn tolerance of seeds during imbibition, while not causing consistent increase in Mn and Fe accumulation in mature seeds, or changing the allocation pattern of these metals. Zinc concentrations, however, were consistently increased in bulk samples.

Summary: The ribosome stalling at AUG-stop sequences plays a critical role in regulating the expression of NIP5;1 in Arabidopsis thaliana in response to boron conditions, with boric acid triggering this process. Through ribosome profiling analysis, hundreds of translationally regulated genes functioning in various biological processes were identified, with a particular emphasis on the role of uORFs. The presence of minimum uORFs (AUG-stops) suggests these elements play a global role in responding to boron, as evidenced by the increased ribosome occupancy of stop codons under high-boron conditions.

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 low phytic acid trait in soybeans is conferred by loss-of-function mutations in specific genes, leading to potential negative effects on seed vigor. However, the benefits of this trait outweigh the drawbacks, prompting the need for a deeper understanding of the molecular basis behind the negative effects. Transcriptomic data analysis reveals that lpa seeds have increased stress sensitivity due to disruptions in various metabolic processes, potentially affecting seed germination. This study contributes valuable insights into the regulatory elements governing seed viability and germination in lpa soybeans.

Summary: Increased CO2 concentration reduces the zinc and iron content in Arabidopsis seeds. This reduction can be mitigated by reducing the CO2-induced decrease in transpiration. Mutants in the ACA7 gene, which is expressed in guard cells, exhibit higher transpiration and higher seed Fe and Zn content under elevated CO2 conditions.

Summary: This study found that calcium influences uranium uptake and toxicity in the terrestrial plant Arabidopsis thaliana, affecting plant growth and oxidative stress. Uranium, in turn, influences calcium uptake and distribution. The expression of calcium transporters is also influenced by uranium and calcium channel blockers.

Summary: This study analyzed the image of kefir biofilms associated with Acai extract. The concentration of Acai berry was found to influence the surface morphology and fractal dimension of the biofilms. The results suggested that a concentration of 40 to 60 ml of Acai berry led to saturation of the biofilm surface. The intermediate sample produced with 20 ml of Acai berry showed promise as a skin dressing.

Summary: The influx of matter from impacting meteoroids and hydrothermal crater weathering plays an important role in modifying the rock and mineral inventory of young planets. These processes not only affect the geochemical environment of early planets like Mars, but also the prebiotic chemistry on early Earth. The study found that both plasma-initiated synthesis during impact and post-impact thermochemistry can produce nucleobases and amino acids, with the latter being essential in the formation of intermediate species.

Summary: We investigated the impact of annealing temperature on the structure and surface morphology of n-ZnO/p-ZnO homojunctions and n-ZnO/p-NiO heterojunctions transparent structures deposited on quartz (Q)/ITO substrates by radio frequency-sputtering. XRD analysis revealed the wurtzite hexagonal structure and (002) preferred growth direction of ZnO. Morphological analysis showed that the roughness of the film varied with increasing annealing temperature. Particle size and shape dictated the growth dynamics of p-ZnO homojunctions and p-NiO heterojunctions respectively. Fractal analysis demonstrated the similar spatial complexity and topographical uniformity of p-ZnO homojunctions, while n-ZnO/p-NiO heterojunctions had different growth dynamics. These results highlight the crucial role of annealing temperature in determining the structure, surface morphology, and growth dynamics of these transparent structures.

Summary: In this study, the effect of different contents of multiwall carbon nanotubes (MWCNTs) on the optical and electrical properties of polyaniline was investigated. The MWCNTs/polyaniline nanocomposites were deposited on ITO coated glass as substrate using the spin-coating technique. Atomic force microscope images were used to analyze the 3-D microtexture parameters of surface texture factors and fractal dimension. Optical spectroscopy was used to study the transmission variations, optical bandgap, absorption coefficient, and skin depth of samples with different concentrations of MWCNTs. The resistance of the nanocomposite films exposed to H-2 gas was also monitored.

Summary: We developed an artificial neural network method to accurately characterize key physical parameters of plasma and mitigate common issues in evaluating laser-induced breakdown spectra. We trained the neural network on xenon spectra and compared the results with a standard model. This method offers a comprehensive approach for geochemical analysis, particularly in detecting xenon in geochemical systems, with a significant speed improvement and minimal input information required.
