BMC Plant Biology, 2010 Background Two thaumatin-like proteins (TLPs) were previously identified in phloem exudate of hybrid poplar (Populus trichocarpa × P. deltoides) using proteomics methods, and their sieve element localization confirmed by immunofluorescence.

Frontiers in Plant Science, 2013 The pressure flow model of phloem transport envisaged by Münch (1930) has gained wide acceptance. Recently, however, the model has been questioned on structural and physiological grounds.

Foliar Phenotypic Plasticity Reflects Adaptation to Environmental Variability
Plants, 2023 Arabidopsis thaliana ecotypes adapted to native habitats with different daylengths, temperatures, and precipitation were grown experimentally under seven combinations of light intensity and leaf temperature to assess their acclimatory phenotypic ...

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.

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 ...

P-proteins in Arabidopsis are heteromeric structures involved in rapid sieve tube sealing
Frontiers in Plant Science, 2013 Structural phloem proteins (P-proteins) are characteristic components of the sieve elements in all dicotyledonous and many monocotyledonous angiosperms.

Viral and cellular factors involved in phloem transport of plant viruses
Frontiers in Plant Science, 2013 Phloem transport of plant viruses is an essential step in the setting-up of a complete infection of a host plant. After an initial replication step in the first cells, viruses spread from cell-to-cell through mesophyll cells, until they reach the ...

Interactions among tobacco sieve element occlusion (SEO) proteins [PDF]
Plant Signaling & Behavior, 2012 Angiosperms 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-proteins. Following injury, P proteins disperse and accumulate as viscous plugs at the sieve plates to prevent ...

How phloem-feeding insects face the challenge of phloem-located defenses
Frontiers in Plant Science, 2013 Due to the high content of nutrient, sieve tubes are a primary target for pests, e.g. most phytophagous hemipteran. To protect the integrity of the sieve tubes as well as their content, plants possess diverse chemical and physical defense mechanisms. The

Phloem development in nematode-induced feeding sites: The implications of auxin and cytokinin
Frontiers in Plant Science, 2013 Sedentary plant parasitic nematodes such as root-knot nematodes and cyst nematodes induce giant cells or syncytia, respectively, in their host plant’s roots.
