PGPB administration influences the cross-talk and interactions of rhizosphere and endophyte microbial communities in sunflower.

ABSTRACT: Plant Growth Promoting Bacteria (PGPB) represent a promising strategy for sustainable agriculture, offering the potential to modulate plant-associated microbiomes and enhance crop resilience. This study evaluated the impact of three microbial consortia (among Bacillus, Lactobacillaceae and Paenibacillus) on the rhizosphere and root endophytic microbiota of two sunflower (Helianthus annuus) genotypes: a hybrid (LST907 - Olival) and an open-pollinated variety (Peredovick), over two consecutive growing seasons. High-throughput 16S rRNA amplicon sequencing revealed that PGPB inoculation induced significant modulation of microbial communities, with strong genotype- and year-specific responses. Inoculants selectively enriched key beneficial taxa, including Pseudomonadaceae,
