Fig. 1From: Transcriptome analysis provides new ideas for studying the regulation of glucose-induced lignin biosynthesis in pear calliGlucose treatment significantly increased the lignin content of calli. A Calli treated with 0% glucose (CK). B Calli treated with 4% glucose (GLU). C The lignin contents of CK and GLU. D cell outline of CK. E and F Lignin autofluorescence of CK. G cell outline of GLU.
