Gigaspora rosea strain:DAOM 194757 Genome sequencing and assembly. Gigaspora rosea strain:DAOM 194757

Species from the family of Gigasporaceae (Order Diversipsorales) form large hyphae and big spores (>200µm). According to plant hosts, Gigaspora spp can develop different types of intracellular structures, i.e. arbuscules and coils. Gigaspora rosea DAOM194757 can be easily cultivated on entire plant in pots and in vitro on root organ culture. Due to their ability to form long germinating hyphae, it was used to characterize the response to strigolactones (an early plant symbiotic signals) and the synthesis of lipo-chito-oligosaccharides (fungal symbiotic signals). G. rosea is mainly found in non perturbed soil. Genome comparison with R. irregularis and other phylogenetically distinct species will give clues in deciphering shared and specific features involved in the symbiotic biology of AM fungi.
