METHODS: According to adherent + Thy1.1 antibody and complement-purification method, cranium was opened to expose olfactory bulb. Thereafter, two olfactory bulbs were obtained to remove cerebral pia mater, blood capillary, and peripheral tissues; additionally, olfactory nerve layer and olfactory bulb granular layer were sheared into 1-mm3 pieces for extract single-cell suspension. The cells were adjusted at the density of 1×107 /L and incubated with poly-l-lysine-coated culture bottle or culture plate in 5% CO2 incubator at 37 ℃. On the third day, cells were cultured with serum-free DMEM/F12 culture media.

This observation provided a strong support to the point that most leaves export the most of assimilates in the light time. Plasmodesmal densities between SE/CC, CC/PP, PP/PP and PP/BSC (bundle-sheath cell) decreased in weak light. Plasmodesmata were observed between CC/SE (nacreous-walled sieve element), PP/BSC in branch veins in normal light intensity, but not in weak light. Thus apoplasmic pathway may be the main mode of transport of assimilates in weak light, however symplasmic pathway may be the main mode of transport of assimilates in normal light intensity.
