Bacterial community shifts in Fusarium-induced avocado root rot and the antagonistic potential of Bacillus siamensis NB92
Avocado root rot, driven by soil-borne fungi such as Fusarium spp., poses a major challenge to global avocado production. The rhizosphere microbiome is critical for plant health, yet the impact of root rot on bacterial community structure and its implications for disease management remain poorly understood. Here, we combined culture-independent 16S rDNA amplicon sequencing with culture-dependent isolation to characterize bacterial communities in healthy and Fusarium-infested avocado bulk and rhizosphere
Fungal dynamics and biocontrol potential in Fusarium-induced avocado root rot soil
PURPOSE: Fusarium-induced root rot poses a significant threat to avocado production, yet the mechanisms linking fungal community dynamics and biocontrol potential in affected soils remain unclear. This study aimed to compare fungal community composition, diversity, enzyme activities, and potential biocontrol agents in healthy and diseased avocado soils. METHODS: We employed high-throughput sequencing, quantitative PCR, soil physicochemical and enzymatic analyses—including β-glucosidase, urease,
