Identification and growth-promoting effect of endophytic bacteria in potato

Abstract In agriculture, Bacillus species are efficient and ecologically tool for promote the growth of plant. Purpose: This study obtains plant growth-promoting (PGP) ability endophytic bacteria isolated from potato tubers. Methods: Using to growth, achieve purpose increasing production. this experiment, growth- promoting strain was verified by laboratory identification field test validation. Result: The isolates were identified as based on a 16S rRNA gene sequence gyrB analysis. DNA hybridization finally it velezensis. Among PGP attributes, K-9 found be positive indole acetic acid (IAA) production, phosphate solubilization, siderophore nitrogen fixation. isolate negative potassium solubilization. quantitative estimation IAA product 9.09 μg/ml. also had produce lytic enzymes such amylase protease. protease activity is 89.16 inoculation improved bioaccumulation roots buds yield in compared uninoculated control plants. Conclusion: These findings give an insight into ways use increase
