Summary: Short-chained aliphatic polyamines are important carbon, nitrogen, and energy sources for marine bacterioplankton. Metagenomic responses of bacterioplankton in the Gulf of Mexico to different PA compounds show that the transformations are carried out by a broad range of taxa and have diverse pathways. PA-transforming genes and taxa vary among different sites, but remain similar among individual compound-amended metagenomes.

Summary: Identification of the polyamine biosynthetic pathway genes in duckweed S. polyrhiza shows the presence of prokaryotic as well as land plant-type ADC pathway but absence of ODC encoding genes. Differential gene expression and transcript abundance of these genes are modulated by exogenous methyl jasmonate, salinity, and acidic pH. The S. polyrhiza genome encodes for complete polyamine biosynthesis pathway and the genes are transcriptionally active in response to changing environmental conditions, suggesting an important role of polyamines in this aquatic plant.

Summary: Research has shown that different foods contain varying levels of polyamines, with plant-based foods such as mushrooms and citrus fruits, and animal-based foods such as cheese and sausages, containing higher levels. The study also found that different cooking processes can impact polyamine levels, with boiling and grilling reducing polyamine levels, while microwave and sous-vide cooking methods have minimal effect on polyamine content.

Summary: This study analyzed the age-dependent variations in polyamine content in peripheral blood cells and plasma, and found that the levels of polyamines decreased with age. Specifically, the 60-70-year-old age group showed significant decreases in polyamine content in blood cells and plasma. Further studies should investigate whether supplementation of polyamines can restore the decreased levels and provide long-term biological benefits.

Summary: Feeding choices in the early months of life have a significant impact on infant growth. This study examines the influence of breastfeeding type and polyamine intake from human milk on infant anthropometric parameters. The results suggest that fully breastfed infants have better anthropometric profiles and higher polyamine intake compared to partially breastfed infants, but the associations between polyamines and anthropometric indicators are weak.

Summary: The biogenic polyamines, spermidine (Spd) and spermine (Spm), are essential for regulating vital cellular functions and are present in high concentrations in all eukaryotic cells. In this study, convenient gram-scale syntheses of C-methylated analogs of Spd were described, which could be used to investigate the cellular functions of polyamines and their metabolism. The biochemical properties of these compounds and the potential for regulating their activity by modifying their structure were discussed.

Summary: The study showed that tomato genotype, maturity stage, and their interactions significantly affected the content and composition of polyamines (PAs). Two genotypes had consistently lower PAs levels, while the variation in PAs content and composition among genotypes was inconsistent over the maturation period. Additionally, certain genotypes exhibited higher levels of PAs during specific maturity stages, making them potentially suitable as health-promoting tomatoes.

Summary: This study quantified the levels of free bioactive amines during germination of tannin and tannin-free sorghum seeds and seedlings. It was found that tannin-free sorghum seeds had higher levels of spermidine, spermine, putrescine, and total amines compared to tannin sorghum. Throughout germination, putrescine was prevalent followed by spermidine. Spermine was only detected in the 7th germination day in tannin sorghum. The findings suggest that by selecting different genotypes, the polyamine contents in germinated sorghum can be modulated for specific food applications.

Summary: Putrescine and spermine have opposite effects on PAMP-induced ROS production and different Ca(2+) signals, leading to differential regulation of gene expression and disease resistance. This study provides evidence for the differential contributions of putrescine and spermine to pathogen-induced immune responses and plant defense.

Summary: Both plant and animal innate immune responses are mediated by membrane-associated receptors and NLRs. The regulation of NLRs is crucial to prevent autoimmune responses, and the chromatin-remodeling protein SWP73A plays a role in suppressing NLR expression and splicing. Bacteria-induced small RNAs can silence SWP73A to activate NLRs during infection.

Summary: Fusarium kuroshium is a fungal symbiont associated with the ambrosia beetle Euwallacea kuroshio, producing metabolites with phytotoxic properties that contribute to the development of Fusarium dieback (FD) disease. Understanding the pathogenicity of F. kuroshium can potentially lead to the development of diagnostic and management tools for FD, providing insights into the interaction of F. kuroshium with its host plants.

Summary: The study found that salicylic acid can significantly modulate polyamine metabolism in Arabidopsis, mainly manifested as putrescine accumulation. This accumulation is caused by increased biosynthesis by ARGININE DECARBOXYLASE 2 and decreased oxidation by copper amine oxidase, independent of NPR1 and MKK4/MPK3, but dependent on MPK6. Additionally, infection by Pseudomonas syringae pv. tomato also triggers SA-dependent putrescine accumulation.

Summary: This study analyzed the subcellular localization and potential interactors of the Arabidopsis thaliana glycine-rich domain protein 2 (AtGRDP2). It was found that the AtGRDP2 protein is localized in the cytosol and nucleus, and the DUF1399 or RRM domains are sufficient for nuclear localization. Furthermore, heterodimeric interactions between AtGRDP2 and specific proteins were observed in different compartments, suggesting the involvement of AtGRDP2 in post-transcriptional processes.

Summary: This article reviews the translational and post-translational regulation mechanisms of polyamine metabolic enzymes in plants. At the translational level, polyamines modulate the activity of upstream open reading frames (uORFs) to control the translation of polyamine biosynthetic and catabolic mRNAs. At the post-translational level, various aspects of the regulation of polyamine metabolic proteins are discussed.

Summary: This research aimed to study the relationship between the SPAD-502 readings and the color space CIE L*a*b* values in two cultivars of Alstroemeria sp. during leaf senescence. The importance of statistical criteria, such as the Akaike information criterion and the parsimonious function, in selecting the best fit calibration functions was demonstrated. The reliability of the functions was tested by comparing the chlorophyll estimated from SPAD readings with their chemical concentrations using Student's t-test. The CIE L*a*b* system was found to be reliable for estimating SPAD readings during leaf senescence of Alstroemeria sp. and could be used instead of SPAD-502.

Summary: This study evaluated the effect of three Metarhizium anisopliae strains on the growth of Arabidopsis thaliana plantlets. The results showed that these strains significantly increased plant fresh weight and total chlorophyll content, and promoted primary root length. Volatile organic compounds analysis revealed differences in the compounds emitted during the interaction between the fungal strains and Arabidopsis. Moreover, the plant growth promoting effect was also observed in Arabidopsis, tomato, and maize plants grown in soil pots.

Summary: This study evaluated the interaction between Fusarium poae and wheat, as well as the potential management strategy using methyl-jasmonate (MeJA) against this important pathogen. The results demonstrated that the effect of MeJA treatment on F. poae growth was isolate-dependent. MeJA treatment reduced fungal biomass in the susceptible wheat cultivar, but no significant differences were observed in the resistant cultivar. Furthermore, the expression of resistance-related genes was induced by F. poae inoculation, and the application of MeJA increased their expressions in resistant cultivars.

Summary: Expression of the TaEPL1 gene in Arabidopsis plants confers increased resistance to bacterial pathogen Pseudomonas syringae and necrotrophic fungus Botrytis cinerea. The expression lines showed reduced disease symptoms and bacterial titers, as well as higher levels of SA- and JA-response genes. EPL1 can be used as an elicitor to generate crops with improved resistance to broad-spectrum diseases.
