FIG. 5.

Localization of fbh1 mRNA in fruit bodies. (a) In situ hybridization in a longitudinal paraffin-embedded section of a mature fruit body hybridized with digoxigenin-labeled antisense fbh1 and viewed under a bright field, which gave a blue label. (b and c) Transverse sections from the upper part of panel a. (e through g) More detailed views of the upper part of panel a. (d) Control hybridized with the fbh1 sense probe. (a through d) Magnification, ×20. (e) Magnification, ×50. (f) Magnification, ×100. (g) Magnification, ×200.
