Endophytic bacteria from potato in vitro activated by exogenic non-pathogenic bacteria

Abstract

The results suggest that potato in vitro supports diverse bacterial endophytes. The community composition of the culturable component of the microflora was remarkably different from that revealed by culture-independent method. Introduction of Pseudomonas fluorescens IMBG163 into potato plant tissue resulted in essential rise of endophytic bacterial species number, however, in the further cloning their number was reduced. Endophytic isolates from potato varieties Zagadka and Nigru, induced by the rhizobacterium, exhibited beneficial for plant characters.
