Xanthomonas species, including active axonopodis pv. malvacearum (X.a.m.), Xanthomonas axonopodis pv. Taum (X.a.p.), and Xanthomonas campestris pv. vesicatoria (X. c. v.), are used to make various products and fractions of seven medicinal plants, including Aristolochi thyme and Aristolochia methanol extracts shown substantial antibacterial activity against all harmful microorganisms when tested on seven different plants. The solvent extracts' antibacterial qualities are more prominent when compared to the entire plant's aqueous extract, suggesting that the antibacterial activity's active components are more soluble in organic solvents. Further testing of the methanolic extract of thyme and aristolochia is shown by comparing the inhibitory activity of the extracts with bacteriomycin 2000 and streptomycin. According to a phytochemical investigation of the plant's leaves, phenolic chemicals are what give the plant its antibacterial qualities. According to the findings, thyme and aristolochia are plants that can manage Xanthomonas.

Drought stress threatens global food security and requires creative agricultural solutions. Recently, phyto-synthesized nanoparticles NPs have garnered attention as a way to reduce food crop drought. This extensive research examines how phyto-synthesized NPs improve crop growth and biochemistry in drought-stressed situations. The review begins with an introduction highlighting the urgency of addressing the agricultural challenges posed by drought. It also highlights the significance of nanoparticles synthesized from photosynthesis in this context. Its purpose is to underscore the importance of sustainable farming practices. This approach is contrasted with conventional methods, elucidating the ecological and economic advantages of phyto-synthesized NPs. This review discusses phyto-synthesized nanoparticles, including titanium dioxide, iron oxide, gold, silver, and copper. In addition, we review their ability to enhance crop growth and stress resistance. The primary focus is to elucidate the effects of phyto-synthesized NPs on plant development under drought stress. Noteworthy outcomes encompass improvements in seed germination, seedling growth, water absorption, photosynthesis, chlorophyll content, the activation of antioxidant defense mechanisms, and the modulation of hormonal responses. These results underscore the potential of phyto-synthesized NPs as agents for enhancing growth and mitigating stress. The review assesses the risks and challenges of using phyto-synthesized NPs in agriculture. Considerations include non-target organisms, soil, and environmental impacts. Further research is needed to determine the long-term effects, dangers, and benefits of phyto-synthesized NPs. Nanoparticles offer a targeted and sustainable approach for improving plant drought tolerance, outpacing traditional methods in ethics and ecological balance. Their mechanisms range from nutrient delivery to molecular regulation. However, the long-term environmental impact remains understudied. This review is critical for identifying research gaps and advancing sustainable agricultural practices amid global water scarcity.

One of the most important areas of nanotechnology is the use of nanoparticles (NPs) for a variety of environmental and biological applications, with silver nanoparticles (Ag‐NPs) gaining a lot attention due to their distinct properties. The current study deals with the synthesis of Ag‐NPs from Dicliptera bupleuroides Nees leaf extract and to determine their antioxidant, antimicrobial potential and effects on wheat seed germination and growth. UV–Visible spectrum revealed a prominent absorption peak at 442 nm, elucidating the conformation of the Ag‐NPs synthesis. Scanning electron microscopy (SEM) showed distinctive triangular, pyramidal, and irregular shape. X‐ray diffraction (XRD) demonstrated their crystalline nature, with average crystallite size of the Ag‐NPs measured at 20.52 nm. Fourier‐transform infrared spectroscopy (FT‐IR) further confirmed the presence of functional groups such as Phenols (O‐H stretch), transition metal carbonyls N‐H, ≡C‐H, C ≡ N, C ≡ C, C‐Cl, C‐Br and O‐H bonds on the surface Ag‐NPs. The antibacterial activity of the Ag‐NPs was most pronounced against Bacillus subtilis, with a zone of inhibition (ZOI) measuring 11 mm ± 0.57 at a concentration of 1000 μg/mL (45% inhibition). Likewise, Ag‐NPs exhibited highest antioxidant potential (73.2%) at 100 μg/mL compared with standard (ascorbic acid) which showed (76%) at the same concentration. Furthermore, the effect of D. bupleuroides mediated Ag‐NPs on wheat seeds growth and germination was recorded maximum at high concentrations (200‐300 ppm). In conclusion, D. bupleuroides mediated Ag‐NPs showed safe, cost effective and environmentally friendly synthesis which can be used as an antibacterial and antioxidant agent as well as for enhancing the growth and seed germination of crop seeds globally.Research Highlights Nanotechnology is the study of nanoparticles for biological and environmental applications. Ag‐NPs among other NPs have received broad attention because of their unique properties. D. bupleuroides Ag‐NPs: 45% antibacterial, 73.2% antioxidant, enhance wheat germination. D. bupleuroides‐mediated Ag‐NPs are both cost‐effective and environmentally beneficial.
