Role of Neurotransmitters (Biomediators) in Plant Responses to Stress.

Plants possess a complex signaling system that enables them to sense and adapt to various environmental stressors, including abiotic factors like extreme temperatures, drought, salinity, and toxic heavy metals. While the roles of hormones and signaling molecules in plant stress responses are well established, the involvement of neurotransmitters-traditionally linked to animal nervous systems-in plant stress physiology is a relatively underexplored area. Recent findings indicate that neurotransmitters such as gamma-aminobutyric acid, glutamate, serotonin, and dopamine play crucial roles in several physiological processes within plants.

Quinoa: A Promising Crop for Resolving the Bottleneck of Cultivation in Soils Affected by Multiple Environmental Abiotic Stresses.

Quinoa ( Willd.) has gained worldwide recognition for its nutritional values, adaptability to diverse environments, and genetic diversity. This review explores the current understanding of quinoa tolerance to environmental stress, focusing on drought, salinity, heat, heavy metals, and UV-B radiation.

Distribution of nitrate/nitrite and toxic metals in the soil-potato system and its health risk assessment in Iran.

Potato is one of the essential food products whose health quality is greatly influenced by soil contamination and properties. In the current study, we have investigated the physicochemical characteristics of agricultural areas and the accumulation of nitrite/nitrate and metals in potato products in Hamedan, Iran. After determining the physicochemical characteristics of soil samples from four agricultural regions of Hamedan, 48 potato samples were collected from these regions.

Tobacco Plant: A Novel and Promising Heterologous Bioreactor for the Production of Recombinant Bovine Chymosin.

The natural source of chymosin, a key enzyme in the dairy industry, is insufficient for rapidly growing cheese industries. Large-scale production of recombinant proteins in heterologous hosts provides an efficient alternative solution. Here, the codon-optimized synthetic prochymosin gene, which has a CAI index of 0.

Therapeutic potentials of N-acetylcysteine immobilized polyrhodanine nanoparticles toward acetaminophen-induced acute hepatotoxicity in rat.

N-acetylcysteine (NAC) is a recommended drug for treating acetaminophen (APAP) intoxication. Due to NAC's low bioavailability, this study aimed to use polyrhodanine (PR) nanoparticles (NPs) as a drug carrier to improve the effectiveness of NAC. After preparation and characterization of NAC loaded on PR, 30 rats were randomly divided into five groups of six.
