Gibberellin (GA) biosynthesis inhibitor PAC promote Dendrobium nobile-Piriformospora symbiosis by upregulating cell wall loosening genes expression
Almost orchid seeds lacking endosperm, depending on mycorrhizal fungal to provide the nutrition for germination. Mycorrhizal fungal Piriformospora indica are compatible mycorrhizal fungi for Dendrobium nobile can quickly promote D. nobile seed germination to protocorm stage.
