 The research conducted by the authors demonstrated that the use of endophytic bacteria could be beneficial for plant growth in marginal lands. In particular, they found that one specific strain of bacillus subtilis LK14 had the ability to increase the chute and root biomass and chlorophyll content of selenium lycopersicum when compared to untreated controls. Additionally, this strain was able to produce high levels of indole-3 acetic acid, IAA, which is known to promote plant growth. This suggests that the use of endophytic bacteria may be a promising strategy for improving crop yields in marginal lands.
