Part of a plant; living tissue that transports the soluble organic compounds made during photosynthesis (known as photosynthate), in particular the sugar sucrose, to parts of the plant where needed.
The soluble sugar dominated in the phloem, while starch dominated in the xylem.

ACP transmits CLas bacterium while feeding on the citrus phloem sap.
3
We also identify 686 gene clusters related to phloem function.
4
The speed of phloem transport can be studied by tracers.
5
These results imply that the phloem sap is a sterol transport system in barley plants.
6
Here a protocol for the use of 14C-labeled photoassimilate to measure phloem transport speed is provided.
7
Here, we present data that identify solanaceous SUT1 proteins with high specificity in phloem companion cells.
8
This work paves the way to future investigations focusing on the molecular network underlying phloem fibre development.
9
And lifting water is just one of the many jobs that the phloem, xylem, and cambium perform.
10
Phenotypic analyses of the fe mutant showed that FT expression is reduced in leaf phloem companion cells.
11
The anatomical analyses indicated that HLB bacterium infection caused phloem disruption, sucrose accumulation, and plugged sieve pores.
12
In this study, we identified and quantified the chemical components of phloem sap from pineapple sweet orange.
13
All compounds detected in the EDTA-enhanced exudate were also detected in the pure phloem sap using centrifugation.
14
The HLB-associated phloem blockage resulted from the plugged sieve pores rather than the HLB bacterial aggregates since 'Ca.
15
That's what we call it when somebody has a cough that brings up sputum, also known as phloem.
16
Taken together, our findings provide insight into movement of satBaMV via the fibrillarin-satBaMV-P20 RNP complex in phloem-mediated systemic trafficking.
