Melatonin as a key regulator in seed germination under abiotic stress

Journal of Pineal Research, Journal Year: 2024, Volume and Issue: 76(1)

Published: Jan. 1, 2024

Abstract Seed germination (SG) is the first stage in a plant's life and has an immense importance sustaining crop production. Abiotic stresses reduce SG by increasing deterioration of seed quality, reducing potential, vigor. Thus, to achieve sustainable level yield, it important improve under abiotic stress conditions. Melatonin (MEL) biomolecule that interplays developmental processes regulates many adaptive responses plants, especially stresses. this review specifically summarizes discusses mechanistic basis MEL‐mediated MEL regulating some stress‐specific common responses. For instance, induced specific include regulation ionic homeostasis, hydrolysis storage proteins salinity stress, C‐repeat binding factors signaling cold starch metabolism high temperature heavy metal activation aquaporins accumulation osmolytes drought stress. On other hand, mediated gibberellins biosynthesis abscisic acid catabolism, redox Ca 2+ are amongst Nonetheless such as endogenous contents, plant species, growth conditions also influence above‐mentioned In conclusion, interacting with different physiological mechanisms.

Role of reactive oxygen species (ROS) on biochar enhanced chromium phytoremediation in the soil–plant system: Exploration on detoxification mechanism

Environment International, Journal Year: 2025, Volume and Issue: 199, P. 109471 - 109471

Published: May 1, 2025

Biochar, as an amendment to enhance phytoremediation of heavy metal contamination, can mediate reactive oxygen species (ROS) generation. However, the role biochar-mediated ROS (BMR) during soil-plant remains inadequately understood. In this study, a combination pot experiments, chemical extraction, and partial least squares path modeling (PLS-PM) was employed investigate BMR dynamics their influence on chromium (Cr) accumulation detoxification in plants. Biochar addition promoted Cr removal efficiency decreased concentrations soil, notably reaching largest 80.60 % lowest concentration 37.53 μmol/kg BC-3 group at 90d. Decreased soil facilitated plant absorbing water-soluble (VI), adsorbed chromate-precipitated (VI) enhanced metabolically inactive compartments (cell walls vacuoles). When biochar added 2 3 (w/w), tissues signaling molecule thresholds. This reduction further stimulated antioxidant enzyme activity, within subcellular organelles, cell wall fixation vacuolar compartmentation, ultimately achieving synergistic integration with accumulation. study provides in-depth understanding BMR-related mechanisms valuable insights into strategies for enhancing mitigation variable valence metals soils.

Nitric oxide (NO) is an important signaling molecule that involved in a wide range of physiological processes plants, including responses to biotic and abiotic stresses. Changes endogenous NO concentration lead activation/deactivation NO-related processes. This paper presents the current state knowledge on biosynthesis scavenging pathways plant cells highlights role post-translational modifications proteins (S-nitrosylation, nitration, phosphorylation) plants under optimal stressful environmental conditions. Particular attention was paid interactions with other molecules: reactive oxygen species, abscisic acid, auxins (e.g., indole-3-acetic acid), salicylic jasmonic acid. In addition, potential common patterns NO-dependent defense against attack feeding by parasitic molting Ecdysozoa species such as nematodes, insects, arachnids were characterized. Our review definitely need for further research involvement between host parasites, especially arachnids.
