From: Identification and growth-promoting effect of endophytic bacteria in potato
Isolation and screening of endophytic bacteria for biocontrol. 1, sampling from thriving plants. 2, isolation from surface sterile tissues using artificial media. 3, molecular identification using ribosomal genes. 4, mass production tests. 5, screening test of endophytic bacteria to plants in greenhouse. 6, endophytic bacteria with growth-promoting effect were tested in the field. 7, the potential PGPR can enter the industrial stage
