A mutation in amino acid permease AAP6 reduces the amino acid content of the Arabidopsis sieve elements but leaves aphid herbivores unaffected [PDF]
, 2010 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.

Sieve Plate Pores in the Phloem and the Unknowns of Their Formation
Plants, 2019 Sieve pores of the sieve plates connect neighboring sieve elements to form the conducting sieve tubes of the phloem. Sieve pores are critical for phloem function.

Identification of new proteins in mature sieve elements [PDF]
Physiologia Plantarum, 2022 AbstractThe 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 a low resistance path for mass flow. The protein machinery in mature sieve elements performs

Phytoplasma-Triggered Ca2+ Influx Is Involved in Sieve-Tube Blockage
Molecular Plant-Microbe Interactions, 2013 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
Applied Sciences, 2019 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 ...

Topos Theory and Consistent Histories: The Internal Logic of the Set of all Consistent Sets [PDF]
, 1996 A major problem in the consistent-histories approach to quantum theory is contending with the potentially large number of consistent sets of history propositions. One possibility is to find a scheme in which a unique set is selected in some way. However,

Live imaging of companion cells and sieve elements in Arabidopsis leaves.
PLoS ONE, 2015 The phloem is a complex tissue composed of highly specialized cells with unique subcellular structures and a compact organization that is challenging to study in vivo at cellular resolution.

Structure of Functional Soybean Sieve Elements [PDF]
Plant Physiology, 1975 Soybean (Glycine max cv. Bragg) petiolar tissue containing translocated (14)C-sucrose was quick frozen, freeze-substituted in acetone or propylene oxide and embedded in Epon. This procedure allowed cytological observations on sieve elements whose functional condition could be verified by microautoradiography.

Solving the Shortest Vector Problem in Lattices Faster Using Quantum Search [PDF]
, 2013 By applying Grover's quantum search algorithm to the lattice algorithms of Micciancio and Voulgaris, Nguyen and Vidick, Wang et al., and Pujol and Stehl\'{e}, we obtain improved asymptotic quantum results for solving the shortest vector problem.
