Identification of phloem-specific proteinaSEOus structure heterogeneity in sieve element of Populus trichocarpa [PDF]
BMC Plant BiologyPhloem, an exceptional plant vascular tissue, facilitates the transport of photoassimilates, RNAs, and other signaling substances from the leaves to the roots throughout the plant. Among the specialized phloem cells are the conductive sieve elements (SEs)

Filamentous sieve element proteins are able to limit phloem mass flow, but not phytoplasma spread. [PDF]
J Exp Bot, 2017 In Fabaceae, dispersion of forisomes—highly ordered aggregates of sieve element proteins—in response to phytoplasma infection was proposed to limit phloem mass flow and, hence, prevent pathogen spread.

Facile Labeling of Sieve Element Phloem-Protein Bodies Using the Reciprocal Oligosaccharide Probe OGA488 [PDF]
Frontiers in Plant Science, 2022 Sieve elements of many angiosperms contain structural phloem proteins (P-proteins) that can interact to create large P-protein bodies. P-protein bodies can occlude sieve plates upon injury but the range of functional and physiological roles of P-proteins

Does aphid salivation affect phloem sieve element occlusion in vivo? [PDF]
J Exp Bot, 2013 To protect against loss of photo-assimilate-rich phloem sap, plants have evolved several mechanisms to plug phloem sieve tubes in response to damage. In many Fabaceae, each sieve element contains a discrete proteinaceous body called a forisome, which, in

PHLOEM UNLOADING: Sieve Element Unloading and Post-Sieve Element Transport
Annual Review of Plant Physiology and Plant Molecular Biology, 1997 ▪ Abstract The transport events from the sieve elements to the sites of utilization within the recipient sink cells contribute to phloem unloading. The phenomenon links sink metabolism and/or compartmentation with phloem transport to, and partitioning ...

Callose deposited at soybean sieve element inhibits long-distance transport of Soybean mosaic virus [PDF]
AMB Express, 2022 The function of callose and its deposition characteristics at phloem in the resistance to the long-distance transportation of Soybean mosaic virus (SMV) through phloem was studied.

Interactions among tobacco sieve element occlusion (SEO) proteins. [PDF]
Plant Signal Behav, 2012 S.1724-1726Angiosperms transport their photoassimilates through sieve tubes, which comprise longitudinally-connected sieve elements. In dicots and also some monocots, the sieve elements contain parietal structural proteins known as phloem proteins or P ...

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.
