Summary: Polyamine metabolism in plants is controlled by multiple genes which are differentially regulated under different physiological conditions. Our study in Arabidopsis thaliana revealed that most genes in polyamine metabolism are not responsive to exogenous polyamines, but there is a difference in response to polyamines between Arabidopsis and rice, as shown by the induction of OsPAO6 gene. These results provide a framework for further study of regulatory modules controlling the expression of each polyamine metabolic gene.

Summary: Plants emit volatile organic compounds (VOCs) to communicate with neighboring plants, potentially through odorant-binding proteins (OBPs). Research suggests that certain plant proteins may have the ability to bind multiple VOCs, allowing for information transfer and defensive responses among plants.

Summary: Abundant volatile compounds play a significant role in fruit aroma across various plant species. The plant hormone jasmonate (JA) regulates the biosynthesis of volatiles such as aldehydes and alcohols, with the transcription factor MdMYC2 being identified as a key regulator in this process. These findings provide valuable insights into the mechanisms by which JA influences volatile biosynthesis in fruit.

Summary: This study found that postharvest treatment with exogenous MeJA can promote the accumulation of secondary metabolites in lily scales, leading to higher antioxidant abilities and nutritional value. By activating the expression of related genes and promoting enzyme activities, MeJA plays a regulatory role in the secondary metabolism of lily. These findings not only help elucidate the mechanism of MeJA in lily, but also provide a simple and efficient method to enhance the nutrients and medicinal ingredients in horticultural production.

Summary: Translation is a crucial cellular process, and the detection and clearance of stalled and collided ribosomes have been extensively studied. Ribosome profiling techniques have revealed nonprogrammed ribosome stalling and leaky translation. Impairment of protein synthesis has been linked to aging.

Summary: MeJA treatment had different effects on the content of steroids and triterpenoids in two genetically different hairy root lines of Taxus x media. The metabolic response to treatment also showed differences between the two lines, but there were common metabolic features.

Summary: This study identified 10 different glucosinolates (GSLs) and explored their accumulation patterns in Isatis indigotica Fort. Additionally, 132 genes involved in the GSL metabolic pathway were discovered. These findings provide a foundation for further research on GSL metabolism and regulatory mechanisms in I. indigotica.

Summary: The prevalence of type 2 diabetes has reached epidemic proportions. Lifestyle interventions such as exercise are the primary therapy options. However, the overall data on the beneficial effects of exercise on metabolism are contradictory, making it difficult to optimize interventions. Innovative exercise strategies and underlying mechanisms are needed to close this therapeutic gap.

Summary: AL6 plays a critical role in cellular phosphate homeostasis and root hair elongation, as well as in the response of Arabidopsis seedlings to jasmonic acid during skotomorphogenesis by modulating chromatin dynamics. Comparison of protein profiles between wild-type and al6 mutant seedlings using a modified Chromatin Enrichment for Proteomics approach highlighted the role of AL6 in chromatin organization and deposition of histone variants in response to internal or environmental stimuli.

Summary: This study evaluated the prognostic value of VRLN MRI in ESRD patients and found that VRLN was significantly associated with MACE. Adding VRLN to a baseline model improved the accuracy of the predictive model. VRLN is a novel marker for risk stratification in ESRD patients.

Summary: The study shows that exogenous methyl jasmonate treatment can enhance the nutritional value and fruit quality of tomatoes. Methyl jasmonate stimulates the production of amino acids and fatty acids, while exogenous ethylene mainly affects sugar metabolism. Additionally, methyl jasmonate significantly affects the accumulation of secondary metabolites, increasing the levels of α-tocopherol and β-sitosterol in the fruits.
