The saprophytic white muscardine fungus Beauveria bassiana (Balsamo) Vuillemin is a potential biocontrol agent against varied insect pests, commercially available mycopesticide in many countries, and extensively used for pest management. It produces several metabolites, such as antibacterial, antifungal, cytotoxic, insecticidal compounds that protect pests plant pathogens, with dual-purpose crop protection, new concept disease This pathogen also beneficial to endophytes are antagonistic diseases promote rhizosphere colonizers growth, inducing systemic resistance. induced responses of fungal enhance genes expressed pathogenesis increase the production pathogenesis-related proteins defense enzymes. infects insects by degrading mechanically chemically their cuticles. promotes provides protection pathogens sustainable agricultural production, reduces usage chemical pesticides.

To evaluate the effect of drought stress on some physiological characteristics six endophyte-infected (E+) genotypes and four endophyte-free (E-) Lolium perenne, an experiment was carried out within a completely randomized design in three replications. In pot culture, one- month conditions for E+ E- L. perenne were handled by limiting irrigation to fulfill 20% field capacity soil. The indicated better resistance E + under terms higher biomass relative water content, deeper root system, greater osmolytes accumulation antioxidant potential. It is concluded that osmotic adjustment (higher content proline total carbohydrate), lower oxidative biomarkers (H2O2 MDA content), enzymatic nonenzymatic components (phenolic, GSH), induction hormone (Abscisic acid (ABA)) are key protective mechanisms stress. contrast, had compliant cope with stress, including enhanced activity, presented lipid peroxidation, improved osmolyte accumulation, ABA up-regulation Lptip1;1 Lptip1;2; aquaporin genes. seems apply defensive mechanism more than use as critical component acclimation conditions.

Various mechanisms are involved in plant disease resistance mediated by entomopathogenic fungi; however, the role of endophytic microbes is unknown. In present study, we showed that incidence northern corn leaf blight caused Exserohilum turcicum (Et) on maize was reduced significantly soil inoculation with Beauveria bassiana (Bb). Meanwhile, B. colonization and E. infection increased diversity abundance bacteria fungi, respectively, while bacterial Bb + Et treatment decreased compared alone. However, relative beneficial significantly, for example, Burkholderia Pseudomonas. Network analyses microbiome complexity after bassiana. Taken together, these results revealed potential mechanism which fungi exert biological control spot disease.

Biocontrol agents can control pathogens by reenforcing systemic plant resistance through acquired (SAR) or induced (ISR). Trichoderma spp. activate the immune system ISR, priming molecular mechanisms of defense against pathogens. Entomopathogenic fungi (EPF) infect a wide range arthropod pests and play an important role in reducing pests' population. Here, we investigated which EPF diseases. We tested two well studied EPF, Metarhizium brunneum isolate Mb7 Beauveria bassiana as commercial product Velifer, for their ability to induce immunity disease several fungal bacterial phytopathogens, promote growth. compared activity these established biocontrol agent, harzianum T39, known inducer broad resistance.
