    "body_text": "Researchers isolated a signaling molecule from a beneficial bacterium associated with citrus roots and report growth gains in field trials involving pepper, celery and mustard. The result points toward microbe-derived inputs that could supplement conventional fertilizer. It is an early agricultural finding: performance across climates, soils and commercial scales remains to be established.",
