Sucrose (Suc), as the precursor molecule for rubber biosynthesis in Hevea brasiliensis, is transported via phloem-mediated long-distance transport from leaves to laticifers in trunk bark, where latex (cytoplasm of laticifers) is tapped for rubber. | Characterization of a vacuolar sucrose transporter, HbSUT5, from Hevea brasiliensis: Involvement in latex production through regulation of intracellular sucrose transport in the bark and laticifers
