Synthetic elicitors are non-toxic chemicals and safe for the environment when applied to plants in a variety of ways. They have been shown to interact with defense mechanisms of plants and cause the production of a wide range of valuable secondary metabolites, both volatile and non-volatile. Plants primed with chemical elicitors are indirectly induced to increase their resistance to herbivore attacks in addition to imparting tolerance or resistance to nearby plants against biotic stresses. The market is stocked with jasmonic acid, salicylic acid, and their derivatives/analogues, which have been shown to either repel or attract herbivores. While phytotoxicity has only been documented in a small number of cases, a significant increase in yield has been reported in a wide range of crops. This review includes a detailed summary of various field and laboratory experiments elucidating the mechanism of action and efficacies of exogenous application and seed priming of synthetic phytohormones on plant growth, development, and yield of different crops.

Blood components play a crucial role in maintaining human health and accurately detecting them is essential for medical diagnostics. A cutting-edge sensor utilizing PCF revealed to precisely identify a wide range of blood components with WBCs (white blood cells), RBCs (red blood cells), HB (hemoglobin), platelets, and plasma. A numerical analysis was performed using COMSOL Multiphysics software to assess the capabilities of the sensor.

L-valine holds wide-ranging applications in medicine, food, feed, and various industrial sectors. Escherichia coli, a pivotal strain in industrial L-valine production, features a concise fermentation period and a well-defined genetic background. This study focuses on mismatch repair genes (mutH, mutL, mutS, and recG) and genes associated with mutagenesis (dinB, rpoS, rpoD, and recA), employing a high-glucose adaptive culture in conjunction with metabolic modifications to systematically screen for superior phenotypes.

Throughout the life cycle of mushrooms, countless spores are released from the fruiting bodies. The spores have significant implications in the food and medicine industries due to pharmacological effects attributed to their bioactive ingredients. Moreover, high concentration of mushroom spores can induce extrinsic allergic reactions in mushroom cultivation workers.

Injecting CO into deep geological formations can be an effective carbon removal and storage technology to mitigate global climate change. Interaction of injected CO with rock formations changes pH and hydrochemistry within the deep injection zone (> 800 m depth). However, cap rocks and multiple tight aquitards typically act as barriers to protect the shallow aquifer from changes in the injection zone.
