Forisome performance in artificial sieve tubes - KNOBLAUCH Sieve Tube Structure Michael Knoblauch Lab Washington

Firstly, quantitative considerations of sieve tube geometry and Ca 2+ inducible forisome deformation observed in vitro indicated that forisomes are too small to occlude sieve tubes in Vicia faba (Peters, van Bel & Knoblauch 2006). Secondly, attempts to employ forisomes to control flow in an artificial microfluidics system failed.Forisomes Michael Knoblauch Lab Washington State Sieve Tube Structure Michael Knoblauch Lab Washington After injury they contract longitudinally and swell radially, which leads to a significant volume increase and occlusion of the sieve tube (B,E,F). In green been forisomes have long terminal extrusions called tails. Their morphology is of taxonomic significance (see Peters et al. 2010 in the literature section.)

The phloem of the angiosperms contains tubular cells, so-called sieve elements (SEs) (Esau 1969).Adjacent SEs form continuous tubes as the cell walls between them are perforated; since these walls resemble sieves, they are referred to as sieve plates (Evert 1990).In the sieve tube network, photoassimilates are distributed throughout the plant body by pressure-driven mass flow Sieve Tube Structure Michael Knoblauch Lab Washington

P-protein agglomerations in sieve tubes that appear to occlude the tube have been reported to allow the passage of fluid and dissolved macromolecules (Kempers et al., 1993) before the recent studies on AtSEOR1 agglomerations (Froelich et al., 2011).To understand the counterintuitive ineffectualness of such apparent sieve tube occlusions, Froelich et al. studied AtSEOR1 sieve tube Sieve Tube Structure Michael Knoblauch Lab Washington Sieve Tube Geometry in Relation to Phloem FlowSieve Tube Geometry in Relation to Phloem Flow Daniel L.

Sieve Tube Geometry in Relation to Phloem Flow

Sieve TubeSpecific Conductivity. The most accurate formula currently available to calculate sieve tubespecific conductivity (k) is the one derived by Thompson and Holbrook (2003b). Earlier studies reported values of k = 0.28 m 2 in Arabidopsis and k = 0.45 m 2 in tobacco (Thompson and Wolniak, 2008). Those calculations were based on Sieve Tube Structure Michael Knoblauch Lab Washington Sieve Tube Structure Michael Knoblauch Lab Washington Sieve Tube Structure Michael Knoblauch Lab Washington Sieve tubes consist of sieve elements which are elongated cells, connected to each other via sieve plates to form a continous tube system that spreads out through the entire plant.
