Article Synopsis
- Agriculture faces increasing food demands due to global population growth, while various biotic and abiotic stresses, especially drought, significantly hinder productivity.
- Drought stress leads to harmful changes in plants, causing stunted growth, reduced photosynthesis, and other negative effects, necessitating the development of effective mitigation strategies.
- Using plant growth promoting rhizobacteria (PGPR) offers a promising alternative to improve drought tolerance and plant health through enhanced root structure, better water retention, and activation of stress defense mechanisms, but commercial use will rely on selecting effective strains.

Soil salinity stress has become a serious roadblock for food production worldwide since it is one of the key factors affecting agricultural productivity. Salinity and drought are predicted to cause considerable loss of crops. To deal with this difficult situation, a variety of strategies have been developed, including plant breeding, plant genetic engineering, and a wide range of agricultural practices, including the use of plant growth-promoting rhizobacteria (PGPR) and seed biopriming techniques, to improve the plants' defenses against salinity stress, resulting in higher crop yields to meet future human food demand.

- The study developed a method using endophytic fungal extracts to synthesize zinc oxide nanoparticles (ZnO NPs) and assessed their antimicrobial and anticancer potential.
- Various characterization techniques confirmed that the synthesized ZnO NPs were pure, mostly hexagonal, and ranged from 34-55 nm in size, demonstrating effective antibacterial and antifungal properties.
- The ZnO NPs showed significant internalization in cancer cells without damaging cell morphology, exhibiting notable anticancer effects at a concentration of 1 μg/mL.
plant extract mediated propellant chemistry route was used for the green synthesis of zinc oxide nanoparticles. Prepared samples were confirmed for their nano regime using advanced characterization techniques such as powder X-ray diffraction and microscopic techniques such as scanning electron microscopy and transmission electron microscopy. The energy band gap of the green synthesized zinc oxide (ZnO)-nanoparticles (NPs) were found between 3.
