Characteristics of phenolic compound accumulation in the anthers of hybrid sterile and fertile tea flowers and CsFLSb gene expression in hybrid sterile and fertile flowers. (A) Anther phenotypes of the hybrid sterile flower with no pollen and fertile flowers. (B) Metabolic analysis of phenolic compounds between hybrid sterile anther and fertile anther. FGs*, Flavone glycosides. (C) CsFLSb expression in hybrid sterile and fertile flowers; the histogram shows the FPKM values.
