ACP transmits CLas bacterium while feeding on the citrus phloem sap.

These results imply that the phloem sap is a sterol transport system in barley plants.

In this study, we identified and quantified the chemical components of phloem sap from pineapple sweet orange.

All compounds detected in the EDTA-enhanced exudate were also detected in the pure phloem sap using centrifugation.

The citrus phloem sap was collected by centrifugation and was analyzed with gas chromatography-mass spectrometry after methyl chloroformate derivatization.

The results of this study will increase our knowledge about the nature and the chemical composition of citrus phloem sap.

Through utilizing the nutrient-rich phloem sap, sap feeding insects such as psyllids, leafhoppers, and aphids can transmit many phloem-restricted pathogens.

In this study, we investigated the micro- and macro-nutrients, nucleotides, and others secondary metabolites of phloem sap from pineapple sweet orange.

The phloem sap composition of many plants has been studied; however, to our knowledge, there is no available data about citrus phloem sap.

The phloem sap composition of CLas-tolerant and sensitive citrus varieties was studied to identify metabolites that could be responsible for their tolerance to CLas.

Thirty-three metabolites were detected in the phloem sap of the studied varieties: twenty 20 amino acids, eight 8 organic acids, and five 5 fatty acids.

To trace vascular transport of ionic and nitrogenous constituents within the plant, the composition of both xylem and phloem saps was thoroughly investigated.

Xylem and phloem saps were collected from plants exposed to both N sources and analyzed for all major contributing ionic and nitrogenous compounds.
