Fig. 8. Lignin contents and gene expression levels in fruit tissues infiltrated with PbMC1a/1b and PbRD21 overexpression constructs.

a Transient assay for the overexpression of PbMC1a/1b and PbRD21 in ‘Dangshan Su’ at 37 DAF. For different gene constructs, the injection sites were labeled A, B, C, and D, and the corresponding noninjected points were labeled a, b, c, and d. Images were obtained 7 days after the infiltration of Agrobacterium. b Lignin contents in the fleshy tissues in the fruits around the injection points (A, B, C, and D) and corresponding noninjected points (a, b, c, and d) (**p < 0.01). c The expression levels of PbMC1a/1b and PbRD21 in the fleshy tissues around the injection points and corresponding noninjected points were analyzed using qRT-PCR
