Potential gene regulation network of the pear single sigmoid pattern showing TCP, NAC, MYB, WRKY, and ankyrin-mediated bZIP-regulated auxin expression. bZIP triggered gibberellin signal transduction to activate gibberellin-responsive proteins. Auxin-induced factors along with bHLH, ZFP, cytochrome P450, and gibberellin-responsive proteins promoted the expression of genes related to cell expansion, which resulted in the middle enlargement of pear fruits
