Sorghum, a vital cereal crop with significant importance in traditional human health systems, faces severe challenges from biotic stresses. This study aimed to assess the morpho-physiological variations and plant growth promoting rhizobacteria (PGPR)-induced defense mechanisms sorghum against Burkholderia sp. infection, well-known cause of bacterial leaf stripe disease. Also, alterations protein band profile exposed infection were assessed via 2-D gel electrophoresis wherein disappearance bands diseased tissues was recorded. The selected PGPR, A. chroococcum Beijerinck 1901 (MCC 2351), B. megaterium 2336), P. fluorescens (NAIMCC B-00340), secreted hydrogen cyanide ammonia, produced lytic enzymes, cellulase amylase. When tested in-planta, sp., applied as foliar spray, more profoundly impacted compared seed coat application, resulting reductions root dry biomass, whole length, total chlorophyll content by 93.9, 73.4 53.8%, respectively, disease-free control. Visible symptoms disease like brown discoloration necrotic lesions observed infected plants. Furthermore, level phytochemicals, proline, malondialdehyde antioxidants, CAT SOD, foliage declined significantly 46.4, 70.2, 20.7, 16.9%, following inoculation Bacillus coat. Additionally, Burkholderia-infected plants exhibited cellular damage, mainly tissues, revealed SEM CLSM. Interestingly, PGPR substantially enhanced measured parameters while reducing levels phytochemicals antioxidants. These findings suggest that chroococcum, megaterium, fluorescens, possessing biocontrol activity, can be employed profitable, environment pocket-friendly approach for managing diseases production under stress, thereby sufficing food demands.

This narrative review aims to examine the therapeutic potential and mechanism of action plant extracts in preventing treating alopecia (baldness). We searched selected research papers on related hair loss, growth, or regrowth, comprehensively compared efficacies, phytochemical components, modulatory targets extracts. These studies showed that various increased survival proliferation dermal papilla cells vitro, enhanced cell growth follicles ex vivo, promoted regrowth animal models vivo. The growth-promoting efficacy several was verified clinical trials. Some phenolic compounds, terpenes terpenoids, sulfur-containing fatty acids were identified as active compounds contained pharmacological effects their associated with promotion survival, proliferation, cycle progression, upregulation factors, such IGF-1, VEGF, HGF, KGF (FGF-7), leading induction extension anagen phase cycle. Those also alleviation oxidative stress, inflammatory response, cellular senescence, apoptosis, downregulation male hormones receptors, entry into telogen Several phytochemicals stimulated signaling pathways mediated by protein kinase B (PKB, called AKT), extracellular signal-regulated kinases (ERK), Wingless Int-1 (WNT), sonic hedgehog (SHH), while suppressing other transforming factor (TGF)-β bone morphogenetic (BMP). Thus, well-selected can have beneficial health. It is proposed discovery targeting aforementioned events will facilitate development new targeted therapies for alopecia.

Plant diseases caused by microbial pathogens pose a severe threat to global food security. Although genetic modifications can improve plant resistance; however, environmentally sustainable strategies are needed manage diseases. Nano-enabled immunomodulation involves using engineered nanomaterials (ENMs) modulate the innate immune system of plants and enhance their resilience against pathogens. This emerging approach provides unique opportunities through ability ENMs act as nanocarriers for delivering immunomodulatory agents, nanoprobes monitoring immunity, nanoparticles (NPs) that directly interact with cells trigger responses. Recent studies revealed application nanoscale agrochemicals strengthen immunity biotic stress enhancing systemic resistance pathways, modulating antioxidant defense systems, activating defense-related pathways reshaping plant-associated microbiomes. However, key challenges remain in unraveling complex mechanisms which influence molecular networks, assessing long-term environmental impacts, developing biodegradable formulations, optimizing targeted delivery methods. review comprehensive investigation latest research on nano-enabled strategies, potential action, highlights future perspectives overcome existing disease management.
