Beyond Mycorrhizae: A Multi‐Kingdom Community in Epiphytic Orchid Roots Reveals Cyanobacteria Intracellular and a Velamen Microbial Refuge
ABSTRACT Orchid biology has long been dominated by the paradigm of mycorrhizal dependency; however, the nutrient acquisition strategies of epiphytic orchids in canopy niches remain poorly understood. Using an integrated approach of multilocus metabarcoding (16S, ITS, 18S) and advanced microscopy (SEM, TEM, CLSM), we ch...
