Title
De novo biosynthesis of defense root exudates in response to Fusarium attack in barley

Other claims from this paper (5)
- Observation Induced barley root exudates inhibited germination of F. graminearum macroconidia.
- Observation Secreted t-cinnamic acid was synthesized de novo within two days of fungal infection.
- Observation t-cinnamic acid accumulated in barley roots during its exudation.
- Observation Nonlignin cell wall phenolics were induced throughout barley root tissues, including necrosed zones.
- Mechanism The authors infer that barley synthesizes and secretes antimicrobial compounds during attack that may mediate resistance.
