Mycobiont identity and light conditions affect belowground morphology and physiology of a mixotrophic orchid Cremastra variabilis (Orchidaceae)

Popis výsledku v původním jazyce

We have investigated whether mycobiont identity and environmental conditions affect morphology and physiology of thechlorophyllous orchid: Cremastra variabilis. We observed underground organ development of the inoculatedC. variabilis plants and estimated their nutritional dependency on fungi using stable isotope abundance. Coralloid rhizomedevelopment was observed in all individuals inoculated with the Psathyrellaceae isolate, and 1–5 shoots per seedling grewfrom the tip of the coralloid rhizome. In contrast, individuals associated with the Tulasnellaceae isolate did not developcoralloid rhizomes, and only one shoot emerged per plantlet. In darkness, δ13 C enrichment was significantly higher withboth fungal isolates, whereas δ15N values were only significantly higher in plants associated with the Psathyrellaceae isolate.We conclude that C. variabilis changes its nutritional dependency on fungal symbionts depending on light availability andsecondly that the identity of fungal symbiont influences the morphology of underground organs.
