A Mixed Bag: The Plant Growth-Promoting Sebacina vermifera Impairs Defense Mechanisms Against Herbivores

摘要: Belowground interactions of plants with beneficial plant growth-promoting microorganisms (PGPM) enhance growth and fitness can alter a plant’s ability to cope its environment. By increasing nutritional uptake, PGPM may indirectly withstand harsh conditions. However, very often the mode action involves interference hormonal balance, which have either positive or negative effects on biotic abiotic stressors. Here we discuss possibility that outcome associating genetically similar Sebacina vermifera Piriformospora indica fungi increases in susceptibility herbivores. Defense mechanisms against herbivores are mainly regulated by jasmonic acid fine-tuned cross talk other phytohormones. Thus, Sebacinales produce IAA shut down defenses interfering ethylene synthesis result promoting but at cost defense-related signaling pathways. That promotion comes expense resistance herbivore attack calls into question mutualistic nature interaction these fungi.
