Variety-dependent seed endophytic bacteria enhance stress tolerance to and bioaccumulation of ciprofloxacin in choy sum (Brassica parachinensis).

ABSTRACT:

Background

Accumulation of antibiotics in crops threatens human health. However, the mechanisms and effects of microorganisms on the uptake and accumulation of antibiotics in crops remain poorly understood. This study aimed to investigate the impact and underlying mechanisms of seed-borne microbiota in root on ciprofloxacin (CIP) accumulation in two choy sum varieties through amplicon sequencing, multiple statistical analyses, and subsequent validation of key bacteria via isolation and co-culturing with plants.

Results

Bacillaceae (mainly Bacillus) was enriched specifically in the roots of CIP high-antibiotic-accumulating variety (HAV) via seed-based vertical transmission activated by the root exudate-derived maleic acid. The relative abundance of Bacillaceae was 9.2 to 27.7
