INFORMATIVE ABSTRACT - Many agriculture cultivations require an extensive use of chemical fertilizers, which cause a significant negative environmental impact, such as surface and groundwater pollution. Among crop plants, tomato has this need but there can be alternatives.
This study wants to take in consideration the plant-growth promoting bacteria (PGPB) with its nutritional benefits that can reduce the usage of chemical fertilizers in the conventional agriculture. Likewise, humic acid can improve plant growth and establish the endophytic PGPB. The application of these bacteria have been considered as an alternative to maintain agroecosystem health and productivity.

The scope of the work is to understand the physiological effects,bacterial colonization and transcriptional responses activated by the endophytic bacterial strains in tomato roots and shoots in the absence and presence of humic acid (HA). So, by their combination seeing the effects.
Through specific experiments, the result is that the humic acid can enhance the growth tomato promoted by endophytic bacterial strains through the activation of hormone and protein metabolism, genes growth, and transcription related processes.
This study gives detailed information on HA-dependent enhancement of growth-related processes stimulated by endophytic bacterial strains in tomato plants and ensures proficient material for further development of efficient PGPB- and HA- based bio stimulants application.
