“…The formation of mycelial strands and sclerotia is important for the successful colonization of new host roots and for survival, respectively. Strand and sclerotial formation are favoured by nutrient depletion and low moisture, whereas potassium‐ and phosphorus‐enriched growth media inhibit strand formation (Bloss and Wheeler, 1975; Kenerley et al ., 1998). During morphogenesis, sclerotial cells synthesize and store copious amounts of glycogen, which accumulates to over 30% of the total dry weight (Ergle, 1947).…”
