The escalating global food demand driven by a gradually expanding human population necessitates strategies to improve agricultural productivity favorably and mitigate crop yield loss caused various stressors (biotic abiotic). Biotic stresses are phytopathogens, pests, nematodes, along with abiotic like salt, heat, drought, heavy metals, which pose serious risks security productivity. Presently, the traditional methods relying on synthetic chemicals have led ecological damage through unintended impacts non-target organisms emergence of microbes that resistant them. Therefore, addressing these challenges is essential for economic, environmental, public health concerns. present review supports sustainable alternatives, emphasizing possible application fungal endophytes as innovative eco-friendly tools in plant stress management. Fungal demonstrate capabilities managing plants against biotic via direct or indirect enhancement plants’ innate immunity. Moreover, they contribute elevated photosynthesis rates, stimulate growth, facilitate nutrient mineralization, produce bioactive compounds, hormones, enzymes, ultimately improving overall resistance. In conclusion, harnessing potentiality represents promising approach toward sustainability practices, offering effective alternative solutions reduce reliance chemical treatments address posed stresses. This ensures long-term promotes environmental economic viability agriculture.

The group of strains constituting the Ralstonia solanacearum species complex (RSSC) is a prominent model for study plant-pathogenic bacteria because its impact on agriculture, owing to wide host range, worldwide distribution, and long persistence in environment. RSSC have led numerous studies aimed at deciphering molecular bases virulence, many biological functions mechanisms been described contribute infection pathogenesis. In this review, we put into perspective recent advances our understanding virulence strains, both terms inventory that participate process their evolutionary dynamics. We also present different strategies developed combat these pathogenic through control, antimicrobial agents, plant genetics, or microbiota engineering.

Currently, management relies mainly biopesticides, which are required for sustainable plant-protection products. Functional peptides candidate biopesticides because they originate from living organisms or synthetic analogs provide mechanisms action against pathogens. Hundreds compounds exist that cover an extensive range activities viruses, bacteria phytoplasmas, fungi oomycetes, nematodes. Natural sources, chemical synthesis, biotechnological platforms may at large scale industry growers.

The natural alkaloids of tryptanthrin and their derivatives have a wide range biological activities. In this research, four series azatryptanthrin containing 4-aza/3-aza/2-aza/1-aza were prepared by condensation cyclization reaction against plant pathogens to develop new product-based bacterial pesticide. Compound 4Aza-8 displayed remarkable growth inhibitory effect on pathogenic bacteria Xanthomonas axonopodis pv. citri (Xac), oryzae Oryzae (Xoo), Pseudomonas syringae actinidiae (Psa) with the final corrected EC50 values 0.312, 1.91, 18.0 μg/mL, respectively, which greatly superior than that (Tryp). Moreover, also showed effective therapeutic protective activities in vivo citrus canker.
