RNA yield and quality from these samples were not adequate for microarray hybridization. B to D, Inverse LMPC. B, Cross section of a poplar twig. C, Dissection of the area between the xylem differentiation zone and the central section. D, Remains after removal of ray-enriched wood. [See online article for color version of this figure.]
