Tobacco BY-2 cell culture is one of the most widely used models in plant biology. The main advantage of BY-2 suspension cultures is the synchronization of cell development and the appearance of polar elongation. In batch culture, BY-2 cells passed through the lag, proliferation, elongation, and stationary phases.

Little is known about mitigation of Cu toxicity through the application of carbon-based nanomaterials including water-soluble fullerene C derivatives. Two derivatives of fullerene were examined: polyhydroxylated C (fullerenol) and arginine C derivative.

Parasites influence not only the physiological processes in the host organism, but also the entire ecosystem, affecting mortality of individuals, the number of offspring through parasitic castration, and matter and energy cycles. Understanding the molecular mechanisms that govern host-parasite relationships and their impact on host physiology and environment remains challenging.

- Widespread oil contamination in soil poses significant risks to microbial life, making it crucial to examine how microbes respond to oil-induced stress and how this affects soil health.
- The study focused on the long-term impact of oil on soil's biochemical properties, comparing metabolite profiles of contaminated and non-contaminated soil, indicating detrimental effects on soil biological activity and increased production of toxic metabolites by fungi.
- Findings revealed that oil contamination significantly alters the metabolic profiles, with a decrease in carbohydrate metabolites and an increase in organic acids, phenolic compounds, and terpenoids, highlighting the impact of oil on soil quality and informing future recovery efforts for affected ecosystems.
The effects of Cu, Ni, and Cd on the Pinus sylvestris metabolome was studied in experimental conditions by gas chromatography-mass spectrometry (GC-MS). Structural changes in plant metabolite network became detectable on day 6 of exposure to the metals, 3-6 days earlier than visual signs of toxicity developed. Differences at the metabolome level arose earlier in a control group of plants, and specific effects of particular metals on the plant metabolome became distinct on day 9.
