A native conjugative plasmid confers potential selective advantages to plant growth-promoting Bacillus velezensis strain GH1-13

Bacillus velezensis strain GH1-13 from rice roots convert to mucoid variants with or without the loss of pBV71. Mucoid phenotypes become sensitive to bacitracin, gramicidin, selenite, and tellurite. These differences enabled us isolating a reverse complement (COM) and a transconjugant of strain FZB42 with the native pBV71.
