This hypothesis is supported by evidence observed from the study of sap collected from the xylem of sugarcane stems, which was very close with the phloem (Welbaum et al., 1992), moreover, it was observed that a fluorescent dye loaded into leaves is unloaded in the phloem of stem and move symplastically via plasmodesmata into the stem parenchyma cells (Rae et al., 2005).
Outside the nucleus TGBp1L88 was demonstrated to reside at the cell wall as small punctate aggregates, which suggests its association with plasmodesmata. On the contrary, TGBp1P88 was diffusely distributed throughout the cytoplasm.

The main characteristics that distinguish members of the order Trentepohliales from other green chlorophycean algae are as follows: differentiated reproductive cells; the presence of [beta]-carotene and haematochrome (i.e., astaxanthin), which color the algal thallus yellow, orange, or red; the absence of a pyrenoid in the chloroplasts; unique flagellar apparatus; and transverse cell walls with plasmodesmata.
