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: PAs play a regulatory role in plant physiological activities through beneficial AM fungi, affecting mycorrhizal development and root colonization. Existing research suggests the importance of PAs in the growth of AM fungi and plant root architecture. The presence of AM symbiosis alters endogenous PAs balance, influencing plant physiological activities and stress tolerance.

Summary: In maize, a rational root structure contributes to high grain yield under dense sowing conditions. The study compared the root structure and distribution characteristics of two maize cultivars, DH618 and SC704, under high-yield and high-density planting conditions. The results showed that DH618 had a well-developed root structure and higher root dry weight compared to SC704, leading to higher grain yield.

Summary: The study evaluated the effects of exogenous polyamines on the adhesive properties of various bacterial strains to human intestinal mucus, finding that polyamines may modulate bacterial adhesion to mucus depending on the bacterial strain and the age at which the mucus is generated.

Summary: This study investigated the pharmacokinetics of oral spermidine supplementation for the first time, and found that spermidine supplementation significantly increased plasma spermine levels, while it did not affect spermidine or putrescine levels. This suggests that dietary spermidine is converted into spermine and contributes to the in vitro and clinical effects of spermidine.

Summary: Human milk is rich in polyamines, which are essential for intestinal maturation and immune system development, while infant formulas have significantly lower levels of polyamines compared to human milk. Spermidine and spermine levels in human milk decrease over lactation, while putrescine remains relatively constant.

Summary: In this study, we investigated the alleviation of zinc-induced stress in Plantago ovata through the exogenous addition of polyamine and its effect on the expression of Metallothionein. Polyamines demonstrated protective and antioxidant properties against zinc-induced stress, reducing lipid peroxidation and down-regulating the expression of Metallothionein. Different concentrations of putrescine and spermidine had varying effects on the total chlorophyll content and antioxidant activities of the plants.

Summary: This study examined the effects of different integrated cultivation treatments on the yield, nitrogen agronomic efficiency (AE(N)), and growth performance of a ratoon rice system. The results showed that the enhanced-high-yield and high-efficiency model (T2) significantly increased grain yield and AE(N) compared with the control model (CK). Moreover, T2 treatment improved stubble weight, non-structure carbohydrate contents, and root attributes.

Summary: Polyamines play a positive role in plant growth and development under drought and saline stress conditions. The levels of putrescine, spermidine, and spermine initially increase before decreasing during these stresses, with tomato plants showing survivability for up to 3 and 2 days, respectively. Different forms of polyamines show complex correlations with transcript levels and gene expression, with specific homologs of polyamine biosynthesis and catabolic genes contributing to their accumulation under different stress conditions.

Summary: The study evaluated the influence of different breastfeeding factors on the polyamine levels in human milk, finding that polyamine levels varied significantly between mothers and tended to decrease over time. Spermidine and spermine concentrations were higher in hindmilk compared to foremilk, and decreased significantly as lactation progressed.

Summary: This study found that Uniconazole can enhance photosynthesis and transpiration rate in mung bean, as well as increase yield and hundred grain weight. However, it also affects root distribution and water uptake in the soil. By adjusting the proportion of roots in different soil layers, it can effectively improve yield and quality of mung beans.

Summary: Inhibition of hypericin biosynthesis can be achieved by impairing the dark glands responsible for synthesizing and accumulating hypericin, with the ability to recover biosynthesis by withdrawing the inhibiting agent glyphosate. The expression of key genes involved in hypericin biosynthesis, such as polyketide synthases and phenolic oxidative coupling proteins, is regulated by glyphosate treatment and withdrawal.
