Several DEG candidates and hub genes (e.g., GERD, SGR, ABCA3, GST, CYP76AD1, CYP76C, and JAZ) in the co-expression network were determined that might be involved in regulating the B. glabra bract color variation of L-a-b values. The gene discussed is ZNF346; the disease is gastroesophageal reflux disease.
