Summary: The study aimed to find the most effective combinations of coumarins and small plant-derived molecules to inhibit quorum sensing (QS) in Chromobacterium violaceum ATCC 31532. Testing two-component compositions showed that 7,8-dihydroxy-4-methylcoumarin, 4-hexyl-1,3-benzendiol, and gamma-octalactone showed a supra-additive anti-QS effect. Combinations of all three molecules resulted in a three- to five-fold reduction in the concentration of each compound needed to achieve EC50 against QS in C. violaceum ATCC 31532.

Summary: R2R3-MYB genes play an important role in plant growth and response to environmental stress. This study identified and analyzed the function of R2R3-MYB genes in Cyclocarya paliurus in response to salt stress. The results showed that the R2R3-MYB genes of C. paliurus have conserved functional domains, and four genes that might be involved in salt stress response were identified.

Summary: Mitochondrial genes are commonly used for PCR-based meat adulteration authentication, but variations in gene copies can lead to quantification errors. This study developed a quantitative method using single-copy nuclear genes to accurately identify mutton adulteration, achieving high recovery rates for simulated mutton-pork, mutton-chicken, and mutton-duck samples.

Summary: A real-time PCR assay targeting a specific single nucleotide polymorphism in Bacillus anthracis genomes was validated, showing high specificity, linearity, and sensitivity. Adapting the assay for reverse transcription PCR on 16S rRNA transcripts significantly increased sensitivity compared to DNA-targeting assays, offering great potential for molecular diagnostics.

Summary: This study reveals that under phosphate limitation, even in the PAO1 type strain, the absence of LasR has no effect on the production of virulence factors and gene expression profile, whereas in a condition of phosphate repletion, the LasR hierarchy is maintained.

Summary: The aim of this study was to identify suitable reference genes for normalizing the expression levels of miRNA in different developmental stages and tissues. Five algorithms were used for stability analysis, and the results identified mtr-MIR160b-p3 and gma-miR394a-5p as the most stable miRNAs during bud development in early-flowering tree peony 'Feng dan', while PC-5p-19095 was the most stable during bud development in late-flowering tree peony 'Lian he'. Additionally, mtr-miR159a was found to be the most stable miRNA during flower development stages of different tree peony varieties.

Summary: This study identified stable reference genes in seven tissues across four developmental stages in minipigs, which can be used to evaluate mRNA expression levels. HPRT1 and 18S were found to be the most stable genes. The expression levels of ACE2 in the intestine and kidney increased significantly at PND28, consistent with the ACE2 expression pattern in humans.

Summary: This study used transcriptomic high-throughput analysis to identify a subset of stably expressed genes from different developmental stages of the gut and associated-bacteriomes of Sitophilus oryzae, which can be used as reference genes in qRT-PCR experiments. Two genes, TAO and YTH3, were selected as suitable genes for comparing transcript abundance in symbiotic and aposymbiotic insects at various developmental stages. These well-conserved genes have the potential to be applied in other insect species, emphasizing the importance of using unbiased methods for reference gene selection.

Summary: Twelve reference genes were selected based on transcriptomic data for stable expression analysis in various organs of Caucasian clover under different stress conditions. Results showed that different reference genes were most stable under different stress conditions, with RCD1 and NLI2 identified as the most stable reference genes across all organs.

Summary: This study evaluated the inhibitory effect of cinnamaldehyde on Listeria monocytogenes at 4 degrees C and investigated the mechanism behind this inhibition. The combination of cinnamaldehyde and low temperature treatment disrupted the gene regulation and caused severe damage to the cell envelope of L. monocytogenes. It was found that cinnamaldehyde interacted with specific proteins, leading to interference with regulator activity. These findings provide new insights for the safety control of chilled meat.

Summary: This study assessed the suitability of ten commonly used reference genes as optimal reference genes in M. officinalis under different abiotic stress conditions and plant organs. The combination of EF-1 alpha and GAPDH was recommended as the best reference genes for gene expression studies in M. officinalis.

Summary: Bumble bees are important alternative pollinators and model insects. This study identified stable reference genes for the bumble bee species and their different lines and tissues using RT-qPCR procedures and four analysis programs. The results emphasized the need to evaluate the stability of candidate reference genes for any differently designed lines and tissue conditions in bumble bee species.

Summary: Identification of specific genes for the Lactobacillus plantarum group through comparative genomics led to the development of an accurate real-time PCR assay for detection. The specificity of primers was confirmed through evaluation on lactic acid bacteria, and the developed assay successfully distinguished and quantified L. plantarum group species or subspecies in probiotic products and fermented food samples.
