Ginseng (Panax ginseng C.A. Meyer) is a medicinal crop that requires a long culture time before it is ready to harvest, thus generating high economic and environmental costs. Symbiotic bacteria that live within the plant provide the host plant with many advantages in terms of metabolism and disease resistance. Here, we isolated endophytic bacteria from various tissues of P. ginseng seedlings using a culture-dependent method and we compared their tissue distribution. In addition, their antimicrobial activity against two fungal pathogens was investigated. Based on 16S rRNA sequencing, we identified 21 bacterial strains from ginseng seedlings. Leaves and rhizomes showed higher bacterial species diversity than root bodies and tails.
While Bacillus strains were detected in all tissues, Xanthomonas and Micrococcaceae strains were specifically isolated from rhizome and leaf tissues, respectively. Fourteen bacterial strains showed antimicrobial activities against Cylindrocarpon destructans and/or Botrytis cinerea, with different activities. Among them, two strains (PgKB29 and PgKB35) showed strong antimicrobial activities against both fungi. Taken together, these results provide a better understanding of endophytic bacteria in P. ginseng seedlings and suggest the possibility of biological control of fungal pathogens using endophytic bacteria.
