Because voltage-driven DNA translocation partially occludes the pore, it reduces by an order of magnitude the accompanying ion current, allowing detection of single-molecule translocation events ...

2014), which determines the translocation efficiency of nutrients ... of SS and IS mediated the development of dorsal vascular cells and affected the sucrose phloem unloading efficiency in rice grain ...

We find that the sieve plate resistance is correlated to the cell lumen resistance, and that the sieve plate and the lumen contribute almost equally to the total hydraulic resistance of the phloem ...
