摘要: Root-knot nematodes (RKN), Meloidogyne sp. hinders functioning of crops and causes global losses in terms productivity yield. are microscopic, obligatory endoparasites with ubiquitous distribution different parts the world. Taking into consideration these aspects, present study was conducted to explore nematicidal activity Streptomyces hydrogenans strain DH-16 against M. incognita regulate its pathogenicity plants. In-vitro experimentation revealed that pretreated seeds solvent culture supernatant lowered root galls infested plants promoted growth Solanum lycopersicum seedlings, through morphological analysis. Additionally, antioxidative defense responses were induced microbes. However, oxidative stress markers considerably reduced after microbial inoculations. Apart from this, secondary metabolites assessed modulated RKN on supplementations. Confocal studies evaluated glutathione accumulation within apices enhancement directly proportional responses. Therefore, current concluded role S. stimulating antioxidant potential along promoting aids. Thus, outcome endorses produced by can be used as safe biocontrol agents also plant agents.
