摘要

Endophytic bacteria are essential for promoting plant growth and increasing plant resilience to various environmental stresses. Although it is well-documented that several endophytic Bacillus species exhibit plant growth-promoting properties, this is the first report on the genome study of Bacillus cereus EMS1, isolated from Musa acuminata G9 in India. This study analyzed the genomics, plant growth traits, and fusarium wilt mitigation potential of Bacillus cereus EMS1. This analysis identified specific genomic features, including potential mechanisms contributing to plant growth promotion, which were also submitted to NCBI (Bioproject ID: PRJNA784269). The in vivo study showed that EMS1 mitigated the impact of Fusarium oxysporum f. sp. cubense on banana plants. Although it did not affect the number of leaves, other parameters influenced by pathogen infection and EMS1 treatment showed notable differences, including fresh weight (Fusarium oxysporum only: 15 g; EMS1 + Fusarium oxysporum: 21 g), dry weight (Fusarium oxysporum only: 1 g; EMS1 + Fusarium oxysporum: 4.7 g), and root length (Fusarium oxysporum only: 6.5 cm; EMS1 + Fusarium oxysporum: 9 cm). Additionally, genomic analysis revealed that the EMS1 genome contains distinctive genes linked to plant growth and antimicrobial activity. Overall, the findings highlight the potential of endophytic Bacillus cereus EMS1 in promoting plant growth and enhancing banana plant resistance against Fusarium oxysporum.
