A decrease in bulk water and mannitol and accumulation of trehalose and trehalose‐based oligosaccharides define a two‐stage maturation process towards extreme stress resistance in ascospores of N eosartorya fischeri ( A spergillus fischeri )

Summary Fungal propagules survive stresses better than vegetative cells. N eosartorya fischeri, an A spergillus teleomorph, forms ascospores that survive high temperatures or drying followed by heat. Not much is known about maturation and development of extreme stress resistance in fungal cells. …
