Plants, Journal Year: 2023, Volume and Issue: 12(23), P. 3982 - 3982

Published: Nov. 27, 2023

Plants, being sessile, have developed complex signaling and response mechanisms to cope with biotic abiotic stressors. Recent investigations revealed the significant contribution of phytohormones in enabling plants endure unfavorable conditions. Among these phytohormones, jasmonic acid (JA) its derivatives, collectively referred as jasmonates (JAs), are particular importance involved diverse signal transduction pathways regulate various physiological molecular processes plants, thus protecting from lethal impacts Jasmonic has emerged a central player plant defense against stress alleviating multiple stressors such drought, salinity, vernalization, heavy metal exposure. Furthermore, growth regulator, JA operates conjunction other through cascade balance development stresses. Although studies reported intricate nature biomolecular entity for mitigation stressors, their underlying mechanism biosynthetic remain poorly understood. Therefore, this review offers an overview recent progress made understanding biosynthesis JA, elucidates complexities pathways, emphasizes pivotal role mitigating Moreover, we also discuss current issues future research directions JAs responses.

Selenium Nanoparticles Boost the Drought Stress Response of Soybean by Enhancing Pigment Accumulation, Oxidative Stress Management and Ultrastructural Integrity

Agronomy, Journal Year: 2024, Volume and Issue: 14(7), P. 1372 - 1372

Published: June 26, 2024

Drought is a persistent and devastating obstacle to crop production, affecting both humanity livestock. The application of selenium (Se) effectively mitigates various types abiotic stresses enhances yield under unfavorable conditions. However, our understanding how nano-Se (nSe) alleviates drought stress (DS) in soybeans still limited. To address this gap, study focused on assessing the effectiveness foliar nSe during reproductive stage soybeans. Three concentrations were applied plants grown pots filled with clay loam soil, simulating DS Our findings reveal that spraying significantly promoted accumulation above-ground dry biomass enhanced relative water content (RWC) photosynthetic pigment over alone-DS treatment. Furthermore, boosted activity contents protective enzymes osmolytes, resulting dose-dependent reduction electrolyte leakage (EL), reactive oxygen species (ROS) accumulation, malondialdehyde (MDA) content. Additionally, improved stomatal characteristics mesophyll cell ultrastructure, further mitigating adverse effects stress. These suggest potential as an effective strategy enhance soybean tolerance potentially improve yields

Potentials of microbe-plant assisted bioremediation in reclaiming heavy metal polluted soil environments for sustainable agriculture

Environmental and Sustainability Indicators, Journal Year: 2024, Volume and Issue: 22, P. 100396 - 100396

Published: April 23, 2024

Crop intensification has increased as human population growth drives the demand for food. However, urbanization, industrialization, and contamination of soil by heavy metal (HM) have become significant challenges to agricultural production. Urbanization activities jeopardize harm health, which is critical environment, ecosystems, sustainable agriculture, global economy. Smelting, mining, other industrial that release toxic HMs into environment significantly reduce with serious consequences both plants humans. Furthermore, achievement agriculture severely inhibited presence HM in soil. Hence, combat subsequent reduction crop output brought on contamination, it necessary engage suitable microbes remove these pollutants. This will result a more productive safety foods, realization food security. Therefore, this study explored efficacy, advantages, limitations current conventional methods remediation well potential like Pseudomonas aeruginosa, Vibrio parahaemolyticus, Alyxia rubricaulis, Maytenus bureaviana reclamation polluted agriculture. Employing natural non-hazardous contaminants, highlighted review, would help improve health quality, increase production, promote outlined United Nations' Sustainable Development Goals.

Levels of heavy metal pollution are increasing due to industrial activities and urban expansion. While cobalt (Co) can be toxic plants at high levels isn't considered essential, it plays a beneficial role in many enzymes is critical for various biological functions. We conducted experiments determine how Adhatoda vasica proliferated shoots react exposure Co concentrations (50-1000 µM). employed physiological biochemical markers elucidate the response mechanisms this medicinal plant. The experiment was two replicates per treatment. statistical analysis based on data from four Interestingly, lowest concentration (50 µM) increased shoot growth by 41.45%. In contrast, higher (100-1000 had detrimental effects development, water content, photosynthetic pigment concentrations. As increased, produced excessive reactive oxygen species (ROS). This ROS overproduction believed primary cause oxidative damage, as evidenced elevated (18.46%-72.84%) malondialdehyde (MDA) detected. stress, non-enzymatic antioxidants were activated concentration-dependent manner. administration significantly different stress-protective compounds shoots, including total (133.18%), ascorbic acids (217.94%), free bound phenolics (97.70% 69.72%, respectively), proline (218.59%), amino (206.96%), soluble proteins (65.97%), carbohydrates (18.52%).
