The present invention discloses an endophytic bacterium JY‑1‑5R of
Aconitum, which was deposited in Guangdong Provincial Microbiological Collection Center on July 18, 2022, with a deposit number of GDMCC No. 62632. The present invention also discloses the use of the above-mentioned
endophytic bacteria JY‑1‑5R of
Aconitum in promoting the growth of
Aconitum and preventing and treating
root rot. The
endophytic bacteria JY‑1‑5R of Aconitum in the present invention can secrete indoleacetic acid, and field experiments have confirmed that the
bacteria can significantly increase the
biomass of Aconitum plants and the yield of
lateral root aconites, and can be used as a dedicated growth-promoting
bacteria for Aconitum; at the same time, the
bacteria has strong
stress resistance and has a significant
inhibitory effect on the
pathogenic bacteria of Aconitum
root rot. Therefore, the strain JY-1-5R is applied to the growth of Aconitum plants and the prevention and treatment of
root rot in the present invention, which belongs to the category of biological
fertilizer and biological control. The
endophytic bacteria colonize in the
plant body and co-evolve with the host, have no adverse effects on medicinal materials, can significantly improve the yield and quality of Aconitum, do not cause environmental
pollution, and have broad application prospects in the green and
sustainable development of the Aconitum industry.
