Table 2 Plasmodesmata density in the cell walls of SE-CC and PC cells in the late storage and fibrous roots of cultivated Arg7 cassava

From: Predominantly symplastic phloem unloading of photosynthates maintains efficient starch accumulation in the cassava storage roots (Manihot esculenta Crantz)

Plasmodesmata density (Number per μm)
SE-CC SE-CC/PC PC/PC
Primary fibrous root 0.013 ± 0.021 0.007 ± 0.019 0.030 ± 0.032
Secondary fibrous root 0.008 ± 0.007 0.001 ± 0.001 0.049 ± 0.022
Elongation stage of tuberous root 0.033 ± 0.026 0.022 ± 0.015 0.095 ± 0.023
Middle stage of storage root 0.040 ± 0.024 0.027 ± 0.018 0.147 ± 0.035
Later stage of storage root 0.032 ± 0.025 0.021 ± 0.021 0.100 ± 0.065
  1. Plasmodesmata were counted on five scopes that were selected from six ultrathin sections for each sample, and the value above are the means ±SE (individuals). Abbreviations: SE, sieve element; CC, companion cell; PC, parenchyma cell
