The sieve element occlusion gene family in dicotyledonous plants. [PDF]
S.151-153Sieve element occlusion (SEO) genes encoding forisome subunits have been identified in Medicago truncatula and other legumes. Forisomes are structural phloem proteins uniquely found in Fabaceae sieve elements.

Identification of new proteins in mature sieve elements
The phloem enables vascular plants to transport photoassimilates from source tissues to heterotrophic sink tissues. In the phloem, unbroken strings of enucleated sieve elements, which lose the majority of their cellular contents upon maturation, provide ...

Sieve element occlusion (SEO) genes encode structural phloem proteins involved in wound sealing of the phloem. [PDF]
S.E1980-E1989The sieve element occlusion (SEO) gene family originally was delimited to genes encoding structural components of forisomes, which are specialized crystalloid phloem proteins found solely in the Fabaceae.

Viral Systemic Movement Is Enhanced by Alteration of a Structural Phloem Protein by the Insect Vector [PDF]
The ability to access and exploit the vascular system is essential for viral systemic spread within plant hosts. Insect‐borne viruses can be released from the vector's stylets into plant phloem together with saliva components that facilitate viral ...

A mutation in amino acid permease AAP6 reduces the amino acid content of the Arabidopsis sieve elements but leaves aphid herbivores unaffected [PDF]
The aim of this study was to investigate the role of the amino acid permease gene AAP6 in regulating phloem amino acid composition and then to determine the effects of this altered diet on aphid performance.

Quantification of plasmodesmatal endoplasmic reticulum coupling between sieve elements and companion cells using fluorescence redistribution after photobleaching [PDF]
Transgenic tobacco (Nicotiana tabacum) was studied to localize the activity of phloem loading during development and to establish whether the endoplasmic reticulum (ER) of the companion cell (CC) and the sieve element (SE) reticulum is continuous by ...

Functional Sieve Element Protoplasts
Sieve element (SE) protoplasts were liberated by exposing excised phloem strands of Vicia faba to cell wall-degrading enzyme mixtures. Two types of SE protoplasts were found: simple protoplasts with forisome inclusions and composite twin protoplasts-two protoplasts intermitted by a sieve plate-of which one protoplast often includes a forisome ...

Branched Pectic Galactan in Phloem-Sieve-Element Cell Walls: Implications for Cell Mechanics [PDF]
A major question in plant biology concerns the specification and functional differentiation of cell types. This is in the context of constraints imposed by networks of cell walls that both adhere cells and contribute to the form and function of ...

Phytoplasma-Triggered Ca2+ Influx Is Involved in Sieve-Tube Blockage
Phytoplasmas are obligate, phloem-restricted phytopathogens that are disseminated by phloem-sap-sucking insects. Phytoplasma infection severely impairs assimilate translocation in host plants and might be responsible for massive changes in phloem ...

Screening Mechanism and Properties of a Cantilevered Vibrating Sieve for Particles Processing
Screening of fine wet particles or near-aperture particles by traditional screen devices is often not quite effective for sieve plugging. Different from traditional rigid regular mesh sieves, a cantilevered vibrating sieve (CVS) with open screen holes ...
