[The formation and symplastic transport function of ectodesmata-like in garlic during the parenchyma cells declining].

Abstract

Using fluorescence and electron microscopy, the ultrastructure and symplastic transport function of Ectodesmata-like (ED-like) were studied in the declining parenchyma cells of garlic during germination period. The results showed that plasmodesmata (PD) were gradually stretched and broke into ED-like. The diameter of PD and the diameter of appressed endoplasmic reticulum (AER) in PD underwent a series of changes. F-actin and myosin might take part in the regulation of the symplastic transport of the ED-like.
