The development of the sieve elements of Pinus pinea
Planta, 1966The fine structure found in the developing and mature secondary phloem of Pinus pinea is described. No longitudinal system of conduits in the sieve elements has been found at any stage in their differentiation. The endoplasmic reticulum undergoes a characteristic series of changes and possible functions are considered.

Sieve Elements of Graft Unions
1990In grafted plants the various relations between scion and stock are based on exchange of heterogeneous substances between the partners; many of them being organic compounds which are translocated in the symplast (see reviews by Brabec 1965 and Carr 1976).

Aspects of sieve element ultrastructure in Primula obconica
Planta, 1966At maturity, the enucleate sieve element of Primula obconica is lined with a parietal layer of cytoplasm consisting of plasmalemma, one or more cisterna-like layers of endoplasmic reticulum, numerous mitochondria and plastids, and a membrane which apparently separates these cytoplasmic components from a large central cavity. The central cavity contains

Aphid activities during sieve element punctures
Entomologia Experimentalis et Applicata, 1994AbstractAphid salivation in sieve elements and phloem sap ingestion were linked to waveforms in the Electrical Penetration Graph (EPG). Non‐viruliferous Rhopalosiphum padi (L.) (Hemiptera, Aphididae) on barley yellow dwarf virus (BYDV) infected wheat could acquire the virus, which was used as an indication for phloem sap ingestion, whereas virus ...

The survival of higher plants is highly dependent upon the phloem path linking assimilate sources and sinks. In an individual plant the elongation, capacity and function of this path have to be finely adjusted to internal and environmental conditions.

Although it is now more than a hundred years since Hartig (1837, 1860) first discovered sieve tubes, and associated solute transport with sieve elements, the structure of functioning sieve elements and the mechanism of phloem transport are still controversial issues.

Sieve element plastids in bamboo
Experientia, 1978The fine structure of the sieve element plastids ofBambusa vulgaris andSchizostachyum lumampao revealed the typical monocotyledonous type (P-type) with the cuneate proteinaceous bodies and lattice-like crystalloids; in addition, characteristically formed vesicles and tubulae could be observed. The diagnostic value of these plastids is also discussed.

Soluble and filamentous proteins in Arabidopsis sieve elements
Plant, Cell & Environment, 2012ABSTRACTPhloem sieve elements are highly differentiated cells involved in the long‐distance transport of photoassimilates. These cells contain both aggregated phloem‐proteins (P‐proteins) and soluble proteins, which are also translocated by mass flow. We used liquid chromatography–tandem mass spectrometry (LC‐MS/MS) to carry out a proteomic survey of ...

Sieve Elements: The Favourite Habitat of Phytoplasmas
2018The sieve elements are the only plant compartments, where phytoplasmas can survive and propagate. Therefore, this chapter is focussed on the specific molecular and cell-biological properties of the sieve element. Sieve element-companion cell complexes arise from (pro)cambial mother cells induced by key genes known to be decisive for sieve-element ...

Occurrence of Sieve Elements in Phloem Rays
IAWA Journal, 1997Solitary sieve elements or groups of sieve elements were encountered in the rays of secondary phloem of Erythrina indica, Guazuma tomentosa, Acacia nilotica, Azadirachta indica, and Tectona grandis trees. These elements were short and possessed simple and compound sieve plates on their transverse to slightly oblique end walls.
