Changes in the potato rhizosphere microbiota richness and diversity occur in a growth stage-dependent manner.

ABSTRACT: Plant root and soil-associated microbiomes are influenced by niches, including bulk and rhizosphere soil. In this work, we collected bulk and rhizosphere soil samples at four potato developmental stages (leaf growth, flowering, tuber elongation and harvest) to identify whether rhizosphere microbiota are structured in a growth stage-dependent manner. The bacterial and fungal microbiota showed significant temporal differences in the rhizosphere and bulk soil. Rhizobacteria were most diverse at the tuber elongation stage, and dominant ASVs identified as Sphingomonas, Rhodanobacter, Sphingobium, Hyphomicrobium, and Solirubrobacter spp. In contrast, rhizosphere fungal diversity peaked at flowering stage, with Lecanicillium spp. being prominent. Furthermore, the abundance of saprophytic fungal g
