The aim of the study was to analyze differential gene expression in Burkholderia pseudomallei strains with different survival rates under cold stress conditions.Materials and methods. Three strains of B. pseudomallei (sequence types ST 46, ST 70, and ST 85) were used as model strains. The RNA was is...

Lactococcus lactis, an internationally recognized safe species of Gram-positive bacteria, produces a variety of antimicrobial peptides. In this study, we examined the irpT gene of L. lactis N8 and its influence on the bacterial stress response. We used the Cre–loxP system to knock out the irpT gene...

The neuroendocrine stress-response is an effective defense mechanism against adverse influences of various nature. This reaction is universal and appears in response to stimuli that are unusual not just for living and habitat of the species, but also for each population. Here we review a progressive...

Copper (Cu) is an essential micronutrient for cyanobacteria, where it functions as a cofactor in key proteins involved in photosynthesis and antioxidant defense. However, at elevated concentrations, Cu becomes toxic, exhibiting algicidal effects by disrupting metal homeostasis and competing for meta...

Objective: Metabolic disruption is a central feature to many neurodegenerative diseases. Despite this, many gaps exist in our understanding of how these perturbations link to the mechanisms of neural disease. In this study, we sought to understand how genetically-controlled, cell-specific loss of py...

This study investigates the relationship between secondary metabolites and stress tolerance in moss species, with a specific emphasis on comparing Antarctic and Korean mosses. Analyses of total phenolic content (TPC) and total flavonoid content (TFC) revealed that Antarctic mosses contain these comp...

In natural environments, the growth and development of plants are frequently impeded by a variety of stresses. These can be categorized into biotic stresses, such as those caused by fungi and bacteria, and abiotic stresses, including factors like low temperature, drought, and salinity (Zhu, 2016). T...

Argonaute (AGO) proteins are the core of the RNA-induced gene silencing complex which regulate a wide variety of processes in plants, from organ development to abiotic stress responses. They have been identified in many plants, but little is known in longan (Dimocarpus longan Lour.), and how AGO fun...

Allelochemicals are recognized as promising algaecides due to their environmental safety. Para-tert-butylcatechol (TBC) and L-lysine exhibit significant potential in suppressing harmful algal blooms (HABs); however, their combined effects and algae inhibition mechanisms remain unelucidated. Therefor...
