Stationary sieve element proteins

Journal of Plant Physiology, 2021
Vascular plants use the phloem to move sugars and other molecules from source leaves to sink organs such as roots and fruits. Within the phloem, enucleate sieve elements provide the low-resistance pipe system that enable bulk flow of sap. In this review, we provide an overview of the highly specific protein machinery that localize to mature sieve ...

Foliar sieve elements: Nexus of the leaf

Journal of Plant Physiology, 2022
In this review, a central position of foliar sieve elements in linking leaf structure and function is explored. Results from studies involving plants grown under, and acclimated to, different growth regimes are used to identify significant, linear relationships between features of minor vein sieve elements and those of 1) leaf photosynthetic capacity ...

Aphid activities during sieve element punctures

Entomologia Experimentalis et Applicata, 1994
AbstractAphid 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 ...

Sieve elements caught in the act

Trends in Plant Science, 2002
Phloem is a puzzling plant tissue owing to the unique natural defence responses of the sieve elements to any kind of mechanical manipulation. Recent non-invasive studies have enabled real-time observation of events in intact sieve tubes, including mass transport, sieve-pore sealing and conformational changes of structural proteins.
