TranscriptomicsTranscription profiling of Arabidopsis phloem
This sudy focuses on the identification of transcripts in the shoot phloem of the model plant Arabidopsis thaliana. Transcripts expressed in the phloem tissue (parenchyma cell, companion cell, sieve element) were excised by laser microdissection pressure catapulting (LMPC). These were compared with ...

TranscriptomicsTranscriptional analysis of phloem-associated cells of potato
To better understand the function of the phloem in plants, we have combined laser capture microdissection (LCM) and RNA-seq for an in-depth transcriptional profile of phloem-associated cells of both petioles and stems of potato. Out of the 27k transcripts assembled that we identified, approximately ...

TranscriptomicsTranscription profiling of flax stems and leaves from 4 week old flax plants to identify transcripts enriched in stem and phloem bast fibres
Stems and leaves from 4 week old flax plants were hybridized to an array of cDNAs from the outer (i.e. phloem enriched) layer of stems of the same age to identify transcripts enriched in stem (and phloem bast fibres).

ProteomicsComprehensive protein profiling of tomato phloem exudates during drought stress and recovery
Phloem is the primary conduit through which photosynthates, hormones, and other biologically important molecules are distributed from aerial plant organs downward and throughout the plant. Increasing evidence suggests that phloem contents are diverse and play a critical role in biotic and abiotic st...

ProteomicsPhloem proteomics in Arabidopsis thaliana: identification of small peptides
The objective of this study is to analyse the protein composition of A. thaliana phloem at different stages of development. For this purpose phloem exudates have been collected at different time points (vegetative stage, floral transition and reproductive stage).

To get further insights into the potential involvement of proteins in long distance signaling of leaves iron status to the root system, a label free experiment was done to determine the protein phloem sap composition in contrasted iron growth conditions in wild type and knock out Arabidopsis mutant ...

ProteomicsPhloem sap extracellular vesicles carry active proteasomes that increase in response to aphid infestation
The morphogenesis of higher plants requires communication among distant organs throughout vascular tissues (xylem and phloem). Numerous investigations have demonstrated that phloem also act as a distribution route for signalling molecules being observed that different macromolecules translocated by ...

Trioza erytreae is a psyllid that feeds on citrus plants and other Rutaceae phloem sap, it is also a vector of the Huanglongbing disease (HLB) a highly aggressive disease caused by the bacteria Candidatus Liberibacter. One of the preferred plant hosts of Trioza erytreae is lemon (Citrus xlimon) plan...

MetabolomicsPrevious infestation by conspecifics leads to a transient increase of the performance of Sitobion avenae aphids on wheat leaves

1. The ecological niche of aphids is largely defined by the phloem sap of plants, which they consume. Previous studies revealed that aphids may change the phloem sap metabolome and that a previous aphid infestation may benefit them. As aphids reproduce parthenogenetically, the performance and pre...
