Summary: Pathogens isolated from fish have significant antimicrobial resistance, posing challenges to economy and public health. Natural antimicrobial substitutes, particularly silver nanoparticles, show potential in combating antibiotic resistance. This study compared biologically produced silver nanoparticles from Origanum vulgare leaves with chemically produced ones and found that the biological production is safer and more effective. The antimicrobial properties of the silver nanoparticles offer promising possibilities for managing fish diseases and improving human health.

Summary: The behavior of AgNPs in simulated gastric fluids with and without pepsin was studied, showing dissolution at the initial stage, particle growth, and aggregation in the absence of pepsin. When pepsin was introduced, individual AgNPs were protected by the formation of a protein corona while still undergoing aggregation. This suggests that both individual NPs and their congregative characteristics should be considered for the evaluation of nanometer-scale materials' safety and toxicity.

Summary: The study on the Ustilago maydis putative homolog of the transcriptional repressor ScNRG1 demonstrated its regulation on various cellular responses to acid pH, including lipid production, gene expression inhibition, filamentous growth, virulence, and oxidative stress. The comparison between wild type strain and nrg1 mutant strain revealed the alteration of 368 genes, with key genes involved in specific stress responses being affected. Furthermore, the NRG1 gene was found to be associated with glucose repression, metabolic adaptation, cellular transport, defense mechanisms, and interaction with acidic pH environment.

Summary: This study evaluated the efficiency of gibberellin inhibitors, paclobutrazol (PBZ) and trinexapac-ethyl (TNE), for in vitro conservation in anthurium, sugarcane, and agave. The results showed that 1 mg L-1 PBZ was the best treatment for anthurium, while 1 mg L-1 PBZ and 3 mg L-1 PBZ or TNE were most effective for sugarcane and agave. The gibberellin-inhibiting compounds PBZ and TNE are low-cost alternatives for in vitro conservation and can be evaluated in other species.

Summary: This study aimed to establish an efficient protocol for the in vitro conservation of Stanhopea tigrina. The effects of various plant growth inhibitors and osmoregulators were evaluated, and it was found that 2 mg L-1 ABA had the lowest impact on shoot height, shoot number, and root number of S. tigrina. During the regeneration process, 2 mg L-1 BAP achieved the regeneration of 3.2 shoots per explant and promoted root growth. The acclimatization process resulted in a plant survival rate of 80%.
