Beyond Mycorrhizae: A Multi-Kingdom Community in Epiphytic Orchid Roots Reveals Cyanobacteria Intracellular and a Velamen Microbial Refuge. [PDF]

Environ Microbiol Rep
This study redefines orchid ecology by revealing Cattleya purpurata roots host a multi‐kingdom microbiota. We report the first intracellular cyanobacteria in orchids, coexisting with mycorrhizal fungi in the cortex. The velamen functions as a structured refuge for specific, highly diverse microbial communities. ChatGPT (OpenAI) was used only for visual

Changes in Foliar Water Uptake Caused by Water Stress in Cattleya Lindl. (Orchidaceae). [PDF]

Physiol Plant
ABSTRACT In response to water restrictions imposed by the epiphytic environment, orchids have developed strategies to increase water‐use efficiency, such as the expression of Crassulacean Acid Metabolism (CAM) and the foliar water uptake (FWU). In a climate change scenario, FWU may emerge as a strategy to reduce water stress during drought.
