Published: March 15, 2024

Climatic changes and global warming produce abiotic stressors that affect plant development productivity. Abiotic stressors, such as drought, salt, cold, heat, significantly impair agricultural crop yields. The endophyte is a type of endosymbiont, usually bacteria or fungus lives inside cells doesn't cause disease in the host plant. This review scrutinizes integral contribution endophytes to augmenting stress tolerance plants. core analysis investigates regulatory role mechanism pivotal physiological aspects plants under conditions. includes their involvement managing water uptake maintaining balance during drought salinity stress, regulating osmotic scavenging reactive oxygen species (ROS). Additionally, explores outlines diverse strategies for inoculating applying enhance Endophytes secondary active compounds defend from diseases extracellular enzymes help colonize hosts. Microbial may thrive poor soil conditions through phytohormone production hazardous chemical degradation. use many processes survive nutritional deficiency, heavy metal temperature. These findings suggest rhizobacteria cope with stress. Still, more research needed understand mechanisms side effects maximize sustainable climate-smart agriculture.

Control of the pinewood nematode (PWN), causal agent pine wilt disease, can be achieved through trunk injection nematicides; however, many pesticides have been linked to environmental and human health concerns. Essential oils (EOs) are suitable alternatives due their biodegradability low toxicity mammals. These complex mixtures plant volatiles often display multiple biological activities synergistic interactions between compounds. The present work profiled eight EOs against PWN in comparison 1:1 mixtures, screen for successful interactions. Additionally, main compounds most were characterized predicted fate mammals emamectin benzoate, a commercial nematicide used PWN. Cymbopogon citratus with Mentha piperita Foeniculum vulgare Satureja montana showed highest activities, half-maximal effective concentrations (EC50) 0.09 0.05 µL/mL, respectively. For these, complete mortality was reached after only ca. 15 min or 2 h direct contact, Their major had higher affinity air water compartments reported very mammals, acute oral dermal toxicities.
