Elucidating the growth-promoting factors of Bacillus amyloliquefaciens on rapeseed through metabolomics.

ABSTRACT:

Background

Plant Growth-Promoting Rhizobacteria (PGPR), such as Bacillus amyloliquefaciens, play vital roles in enhancing plant growth and stress tolerance. This study aims to evaluate the effects of the B. amyloliquefaciens strain Bam22 on the growth and metabolic profile of rapeseed (Brassica napus) seedlings, specifically focusing on uncovering the underlying metabolic mechanisms.

Results

Inoculation with Bam22 significantly promoted rapeseed growth. Compared to the control, plant height increased by approximately 17.1% and root length by 14.4% at 35 days post-inoculation (dpi). While leaf number remained no significant changed, fresh weight showed significant increases of approximately 70.3% (shoot, 7 dpi), 39.4% (shoot, 35 dpi), 23.8% (root, 7 dpi), and 26.8% (root, 35
