20.500.12556/RUL-180474 Biocontrol and growth-promoting potential of Bacillus cereus TuR6 against rhizome rot disease in turmeric (Curcuma longa L.) Biokontrola in potencial spodbujanja rasti bakterije Bacillus cereus TuR6 proti gnilobi korenike pri kurkumi (Curcuma longa L.) Rhizome rot disease caused by Fusarium solani severely limits turmeric (Curcuma longa L.) productivity. This study aimed to isolate endophytic bacterial strains from turmeric roots and screen them for plant growth-promoting (PGP) traits and antifungal activity. Among 10 isolates, strain TuR6, identified as Bacillus cereus (98.68% similarity, GenBank accession: PV565573), showed the highest IAA production (75.41 mg/L), strong phosphate solubilization (PSI 5.32), and positive siderophore, protease, and cellulase activities. TuR6 inhibited F. solani growth by 78.12% in vitro. In greenhouse trials, TuR6 significantly increased plant height (80.57 cm), rhizome yield (371 g/plant), and reduced disease incidence (17.7%). Field experiments confirmed its efficacy, with notable growth and disease suppression improvements under natural conditions. These results highlight B. cereus TuR6 as a potential bioinoculant for enhancing turmeric yield and managing rhizome rot sustainably. endophytic bacteria plant growth-promoting bacteria biocontrol turmeric roots biofertilizer endofitne bakterije bakterije ki pospešujejo rast rastlin biotično varstvo rastlin korenine kurkume biognojilo true false true Angleški jezik Slovenski jezik Članek v reviji 2026-03-10 10:36:14 2026-03-10 10:36:18 2026-03-11 04:38:31 0000-00-00 00:00:00 2026 0 0 9 str. no. 1 Vol. 122 2026 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 632 1854-1941 10.14720/aas.2026.122.1.22954 271100675 Do-2026-Biocontrol-and-growth-promoting-pot.pdf Do-2026-Biocontrol-and-growth-promoting-pot.pdf 1 BDD9EAA239315FBFA95715EB75949331 76b93c645b0244c70b1187860de06598852c072364f111a1dba89c9328df8bf4 8e38c54f-1c64-11f1-a1ba-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=229902 https://journals.uni-lj.si/aas/article/view/22954/20306 1 4eea3932-1c64-11f1-a1ba-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=229901 Biotehniška fakulteta Acta agriculturae Slovenica 0 0 0
