From: Comparative morphology and transcriptome analysis reveals distinct functions of the primary and secondary laticifer cells in the rubber tree

Figure 1

A comparison of the primary and the secondary laticifer cells in cross-sections. (a) Canopy of rubber tree clone RY7-33-97 (7-years old). Red arrows indicate the young shoots where the primary latex for RNA isolation and the bark samples for histological observation were collected, and the pink arrow indicates the region containing both the primary and the secondary laticifer cells. (b–d) Representative cross-sections of the bark of young shoots selected from three biological replicates. Red arrows indicate the primary laticifer cells. The scale bar represents 20 µm; (e) A rubber tree trunk showing the latex in the first tapping. The red arrow indicates where the bark sample was collected for anatomical analysis. (f–h) Representative cross-sections of the bark from tree trunks showing the secondary laticifer cells; The scale bar represents 20 µm.
