Isolation, selection and identification of indigenous bacterial strains having the ability to promote plant growth and antagonise the fungal disease Fusarium oxysporum and root-knot nematode Meloidogyne sp. in Vietnam

Tomato and coffee are very important crops and industrial plants in Vietnam. However, both are severely damaged by the fungus F. oxysporum and the knot root nematode Meloidogyne sp. To date, there are not many biological products that are both effective for prevention and safe for human health and the environment. With the goal of finding beneficial agents for experimental bioproduction in the prevention and suppression of harmful fungal and nematode diseases, this study isolated, selected and identified three indigenous bacterial strains with potential in both plant growth promotion plant and the control of fungal diseases and nematodes harmful to the roots of tomato plants, and ability in plant growth promotion, including strains of Bacillus velezensis TL7, S1 and S2 by sequencing the whole bacterial genome with GenBank codes VEWW00000000, VEWX00000000 and VEWZ00000000, respectively.
