Figure 7

Lignin accumulation and expression of genes involved in S-adenosylmethionine metabolism during in vitro tracheid differentiation from Pinus pinaster callus cells. (a) Microscopic image of Pinus pinaster tracheids developed in vitro. Lignin deposited in a typical band pattern was stained with phloroglucinol. Scale bar on the bottom left represents 10 μm. (b) Lignin contents in culture of Pinus pinaster cells after 0, 7 and 15 days of transfer to induction medium (without hormones, open circles) or control medium (with hormones, closed circles). Values are the means of three independent quantifications ± SE. (c) Relative transcript abundance of genes involved in S-adenosylmethionine metabolism after 0, 7 and 15 days of transferring Pinus pinaster callus cells to induction medium (without hormones, open circles) or control medium (with hormones, closed circles). Values are the means of three independent replicates ± SE.
