Conditions
Pyrus bretschneideri responds to various hormonal treatments through the differential expression of its bZIP transcription factors. Specifically, the plant exhibits specific expression profiles when treated with abscisic acid (ABA). The study also highlights how Pyrus bretschneideri reacts to salicylic acid (SA) to manage abiotic stresses. Additionally, the plant's genetic response is significantly influenced by methyl jasmonate (MeJa). These interactions demonstrate how Pyrus bretschneideri utilizes hormones like abscisic acid, salicylic acid, and methyl jasmonate to regulate growth and development.
