Termites have co-evolved with a complex gut microbiota consisting mostly of exclusive resident taxa, but key forces sustaining this partnership are still poorly understood. The potential for primary reproductives to vertically transmit their (mycobiome and bacteriome) offspring was investigated using colony foundations from field-derived swarming alates Macrotermes subhyalinus . Metabarcoding based on the fungal internal transcribed spacer (ITS) region bacterial 16S rRNA gene used characterize mycobiome bacteriome over foundation time. differed that workers Macrotermitinae changed randomly within between sampling time points, highlighting no close link habitat. ectosymbiont Termitomyces lost early reproductives, confirming absence vertical transmission offspring. Unlike fungi, mirrored Macroterminae. Key genera core OTUs inherited mother persisted in reproductive until emergence workers, enabling explaining why they were found workers. These findings demonstrate parental may greatly contribute maintenance its co-evolution termite hosts at short scales.
