Fig. 1From: Transcriptomic analysis of early fruit development in Chinese white pear (Pyrus bretschneideri Rehd.) and functional identification of PbCCR1 in lignin biosynthesisInvestigation of stone cell and lignin contents in 0, 7, 15 DAP fruits. a Fruit morphology and stone cell phloroglucinol staining of 0, 7, and 15 DAP fruits were performed. b Stone cell contents of 0, 7, 15 DAP fruits. c Lignin contents of 0, 7, and 15 DAP fruits. **Significant differences between the stone cell or lignin levels of the different developmental periods (P < 0.01)Back to article page
