Optimized medium composition in Physalis alkekengi callus culture altered nitric oxide level for inducing antioxidant enzyme activities and secondary metabolites.

Physalis alkekengi L. is a valuable medicinal plant from the Solanaceae family and has multiple therapeutic applications. This study aimed to develop an optimized protocol for callogenesis in P.

Establishment of Physalis alkekengi cell suspension culture: time-dependent behavior of genes related to the steroidal compounds, key enzymes, and physalins under static magnetic field.

Cell suspension culture has the potential to be a valuable source for the bioactive compound productions. In this study, an optimized procedure was established for callus and cell suspension culture of Physalis alkekengi for the first time, and the impact of static magnetic field (SMF, 6 mT) was studied on the high-value metabolic compounds through investigation of signaling molecules and gene expressions at the late log-to-stationary phase. Results showed that the growth regulators of 6-benzyl amino purine (BAP, 1.

Alteration in the callogenesis, tropane alkaloid formation, and gene expression in Hyoscyamus niger under clinorotation.

This study aimed to investigate the effects of clinorotation induced by 2-D clinostat on the growth, tropane alkaloid production, gene expression, antioxidant capacity, and cellular defense responses in the callus tissue of Hyoscyamus niger. Callus induction was conducted by putting hypocotyl explants in the MS culture medium supplemented with 1 mgL 2,4-D and 1 mgL BAP growth regulators. The sub-cultured calli were placed on a clinostat for 0, 3, 7, and 10 days (2.

Impact of sodium pyrophosphate and static magnetic field on : enhancement of astaxanthin accumulation, PAL, and antioxidant enzyme activities.

The microalga is known as a main source of astaxanthin with a strong antioxidant capacity and low growth rate. The induction of growth and astaxanthin content was established in alga using a static magnetic field (SMF) and tetrasodium pyrophosphate (NaPP) as an inhibitor of isopentenyl pyrophosphate (precursor of astaxanthin biosynthesis) translocator between cytosol to plastid. NaPP (0.

Simulated microgravity contributed to modification of callogenesis performance and secondary metabolite production in CannabisIndica.

In vitro plant culture paves the way for meeting the industrial demand of pharmaceutically valuable secondary metabolites. This study intends to monitor how callus cells of Cannabis indica respond to the simulated microgravity (clinorotation; a Man-made technology). Callus initiation resulted from the culture of the leaf explant in a medium supplemented with kinetin (0.

Impact of the Static Magnetic Field on Growth, Pigments, Osmolytes, Nitric Oxide, Hydrogen Sulfide, Phenylalanine Ammonia-Lyase Activity, Antioxidant Defense System, and Yield in Lettuce.

Magnetic fields are an unavoidable physical factor affecting living organisms. Lettuce seeds ( var. cabitat L.

Penconazole induced changes in photosynthesis, ion acquisition and protein profile of Mentha pulegium L. under drought stress.

Effect of penconazole (PEN) treatment on drought-stressed Mentha pulegium L. plants was investigated. Six weeks after sowing, seedlings were grown under soil moisture corresponding to 100, 75, 50 and 25 % field capacity (FC) with or without PEN (15 mg l(-1)) for 4 weeks.
