The physiological impacts of three AMF species and Bacillus thuringiensis (vegetative and endospore forms) in strawberry under different phosphorus availability

Type: article

Abstract: FW, though root P sometimes decreased (0.13 %), suggesting a growth-dilution effect. In contrast, In P-available soil, dual inoculation reduced AMF colonization (11 %), root length (16 cm), and biomass (0.45 g DW), but increased root P (0.19 %), reflecting indicating downregulation of symbiosis when external P is sufficient. PAL and POD activities were modulated by both P availability and bacterial form. FTIR analyses showed that vegetative cells enhanced polysaccharide deposition, whereas endospores increased lignin-associated features. Multivariate analyses (PCA, NMDS) identified P availability as the primary driver of plant-microbe interaction outcomes. Overall, the benefits of AMF-B. thuringiensis were most evident under conditions of insoluble P, emphasizing their potential to enhance nutrient uptake in low P soil.
