Determination of the phloem transport pathways and destination of photosynthates in soybean using autoradiography and fluorescent tracer imaging [PDF]

open access: yesPlant Signaling & Behavior
Vascular tissues transport water and nutrients in plants, with the phloem distributing photosynthates from source to sink. The direction of phloem transport is determined by the positional relationship between sources and sinks and by vascular ...

Investigating phloem transport dynamics in Arabidopsis through compartmental modelling of positron emission tomography data [PDF]

open access: yesPlant Methods
Background Phloem is the long-distance transport tissue of vascular plants in which photoassimilates are distributed from sources (e.g., leaves) to sinks (e.g., roots, fruits).

A Proposed Drought Response Equation Added to the Münch-Horwitz Theory of Phloem Transport [PDF]

open access: yesFrontiers in Plant Science, 2020
Theoretical and experimental evidence for an effect of sieve tube turgor pressure on the mechanisms of phloem unloading near the root tips during moderate levels of drought stress is reviewed.

An update on phloem transport: a simple bulk flow under complex regulation [version 1; referees: 5 approved] [PDF]

open access: yesF1000Research, 2017
The phloem plays a central role in transporting resources and signalling molecules from fully expanded leaves to provide precursors for, and to direct development of, heterotrophic organs located throughout the plant body.

Phloem transport: a review of mechanisms and controls. [PDF]

open access: yesJournal of Experimental Botany, 2013
It is generally believed that an osmotically generated pressure gradient drives the phloem mass flow. So far, this widely accepted Münch theory has required remarkably few adaptations, but the debate on alternative and additional hypotheses is still ongoing.

Structural and functional heterogeneity in phloem loading and transport [PDF]

open access: yesFrontiers in Plant Science, 2013
The phloem is often regarded as a relatively straightforward transport system composed of loading (collection), long-distance (transport) and unloading zones.

Characterizing the circular RNA landscape in phloem sap of Brassica napus. [PDF]

open access: yesPLoS ONE
In plants, long-distance transport and phloem-mediated signal distribution play crucial roles in regulating stress adaptation and development. Phloem sap contains various types of RNAs, including small RNAs (sRNAs), messenger RNAs (mRNAs), and long ...

Coordination Between Phloem Loading and Structure Maintains Carbon Transport Under Drought

open access: yesFrontiers in Plant Science, 2022
Maintaining phloem transport under water stress is expected to be crucial to whole-plant drought tolerance, but the traits that benefit phloem function under drought are poorly understood.

Low Night Temperature Affects the Phloem Ultrastructure of Lateral Branches and Raffinose Family Oligosaccharide (RFO) Accumulation in RFO-Transporting Plant Melon (Cucumismelo L.) during Fruit Expansion. [PDF]

open access: yesPLoS ONE, 2016
Due to the importance and complexity of photo assimilate transport in raffinose family oligosaccharide (RFO)-transporting plants such as melon, it is important to study the features of the transport structure (phloem) particularly of the lateral branches

Transport of sucrose, not hexose, in the phloem [PDF]

open access: yesJournal of Experimental Botany, 2012
Several lines of evidence indicate that glucose and fructose are essentially absent in mobile phloem sap. However, this paradigm has been called into question, especially but not entirely, with respect to species in the Ranunculaceae and Papaveraceae. In the experiments in question, phloem sap was obtained by detaching leaves and placing the cut ends ...
