Summary: The study investigating the effects of diatom Ditylum brightwellii on Phaeocystis globosa colony development found that moderate abundance of the diatom increased the number and size of colonies, while high abundance had a decreased effect. The cell-free filtrate experiments showed that cultures from the exponential phase of D. brightwellii stimulated P. globosa colony formation, while filtrates from the senescence phase had an inhibitory effect. D. brightwellii influences P. globosa colony formation by regulating the growth of P. globosa solitary cells.

Summary: In this study, bZIP transcription factors (TFs) in the diatom Phaeodactylum tricornutum (Pt) were analyzed using bioinformatic and molecular methods. Twenty-two PtbZIP genes were identified and classified into seven clades based on phylogenetic relationships, conserved motifs, and gene structures. Among them, PtbZIP12 and PtbZIP13 were identified as a putative pair of duplicated genes. It was also observed that laminarin content showed a circadian rhythm. Based on these findings, a regulatory mechanism for laminarin biosynthesis was proposed in P. tricornutum.

Summary: This study evaluated the antimicrobial and antibiofilm activities of black pepper essential oil (BPEO) and piperine and their effects on gene expression in a multispecies biofilm. Piperine was found to effectively control the biofilm and upregulate genes involved in biofilm formation in Listeria monocytogenes, Salmonella Typhimurium, and Pseudomonas aeruginosa.

Summary: In open sea, copper concentration is greatly reduced, impacting the uptake systems and growth of phytoplankton. Cells adapt to low copper by downregulating anabolic and energy-yielding reactions, while upregulating oxidative stress defense systems. The chloroplast is identified as the primary target of low copper availability in Thalassiosira oceanica.

Summary: This study investigates the transcriptomic responses of the diatom Skeletonema marinoi to low salinity environments. The results reveal that low salinities induce changes in cellular metabolism and different strains of the diatom exhibit varying responses to low salinity. This study highlights the importance of intraspecific variation in gene expression in diatom responses to environmental change.

Summary: This study found that Caenorhabditis elegans is sensitive to gene expression changes induced by AFB1, B(a)P, and PCB1254, but insensitive to TCDD effects. Despite the absence of differential expression in genes encoding DNA repair and cell cycle checkpoint proteins, the transcriptional responses of metabolic enzymes suggest that the nematode is capable of metabolizing AFB1, B(a)P, and PCB1254.

Summary: The combined treatment of 1-MCP and NO effectively delayed peach ripening and preserved fruit quality. NO delayed fruit senescence by stimulating antioxidant enzymes, while 1-MCP outperformed NO in slowing down respiration rate, inhibiting ethylene production, maintaining high firmness, and reducing ROS content. NO treatment showed a greater influence on phenolic compounds, especially anthocyanins, flavanones, and flavones, according to LC/MS analysis.

Summary: This study focuses on the impacts of three distinct NPs on the Caribbean oyster Isognomon alatus through dietary exposure, revealing significant changes in gene expression in response to NPs and arsenic exposure. The interaction between NPs and As may have a protective effect by reducing surface reactivity of contaminants.

Summary: Bagging is a crucial cultivation measure that affects the quality of peach fruit by regulating exposure to light. This study investigated the effects of bagging on the content of phenolic compounds in peach fruit and identified the most sensitive compounds to bagging treatment. The study also explored the regulatory role of bagging on phenolic synthetic-related genes. The results showed that bagging affected the accumulation of different phenolics in different peach cultivars and light intensity played a significant role in the accumulation of anthocyanins and other phenolic substances in peach fruit. Additionally, the expression of structural genes and transcription factors related to phenolic synthesis was regulated by bagging and light conditions. These findings provide a foundation for understanding the regulation mechanism of light on the synthesis of phenolic compounds in peach fruit.

Summary: Supercritical water (SCW) technology can efficiently recover toxic or complex chemical wastes, but salt deposition and corrosion hinder its commercial applications. Research on salt solubility in high pressure/temperature water provides ideas and references for follow-up research on metal recovery.
