The isolated strains were <em>Bacillus velezensis</em>, <em>B. subtilis</em>, <em>B. tequilensis</em>, <em>B</em>. <em>safensis, B. altitudinis</em>, and <em>Pseudomonas psychrophila</em>. These strains demonstrated <em>in-vitro</em> phosphorus solubilization, nitrogen fixation, ammonification, nitrification, enzyme releasing, phytohormones production, and high biocontrol capacity of over 75%. SC6 and RI3 (both <em>B. velezensis</em>) and P10 (<em>P. psychrophila</em>) exhibited outstanding performance. They significantly promoted peanut root biomass by more than 50% and leaf area by 30%, with increased chlorophyll content index and leaf relative water content, particularly under water stress conditions (40% field capacity). According to the results, RI3, SC6, and P10 could be classified as PGPR, which supports the results obtained in other field studies with these same microorganisms.

Double minutes (DMs) are extrachromosomal circular chromosomes that carry amplified oncogenes or drug resistance genes, and they are closely associated with tumorigenesis and drug resistance. To investigate the role and regulatory mechanisms of double minutes in the malignant progression of gastric cancer, we utilize bioinformatics methods to analyze genomic copy number variation data from the CCLE cell line database and TCGA solid tumor database. We analyze and summarize the genomic features of tumor samples with double minutes. Based on these features, we classify gastric cancer samples. We use the FANTOM5 database, R package \"GenomicRanges\", Bedtools, and MEME SUITE to analyze the functions of the enhancers on double minutes and their regulated target genes in gastric cancer. Next, we apply the CIBERSORT package and the GDSC drug database to analyze immune cell infiltration and drug resistance in gastric cancer samples with and without double minutes from TCGA. The results show that the genome with a copy number greater than 10 and genomic fragments longer than 50 kb play a significant role. The regulatory role of double minutes enhancers affects drug resistance and tumor immunity, with disruptions in the enhancer-transcription factor-target gene regulatory loops also linked to tumor immunity. Furthermore, the target genes regulated by double minutes enhancers not only alter the expression of immune-related genes but also contribute to increased drug resistance to common chemotherapy agents in gastric cancer samples. High expression of drug resistance-related target genes in gastric cancer samples with double minutes is closely associated with poor prognosis.

Nile tilapia juveniles were injected with BV at doses of 0, 3, 6, 9, and 12 mg/kg of fish weight. Observations were made on the 14th day post-injection (DPI).

Similarly, the activity of intestinal enzymes (amylase, protease, and lipase) showed no significant changes.

On the 14th DPI, fish injected with BV at doses of 3, 6, and 9 mg/kg exhibited higher antioxidant enzyme activities compared to the control and the highest dosage group (12 mg/kg).

DEGs in the skin were primarily down-regulated in golden genotypes and associated with neural crest development and melanin pigmentation pathways. Besides these DEGs involved in the classic melanin pigmentation pathway of vertebrates, 14 DEGs were also observed to be related to melanogenesis. In muscle transcriptomes, there was an enrichment of GO terms associated with growth factors and cellular lipid catabolic processes. Specifically, DEGs related to growth factor binding exhibited a down-regulation, while those related to lipid metabolism showed an up-regulation in mutant genotypes. These findings agree with observed phenotypic changes. Furthermore, several DEGs associated with muscle function and mobility were up-regulated.
