Determination of the phloem transport pathways and destination of photosynthates in soybean using autoradiography and fluorescent tracer imaging [PDF]
Plant Signaling & BehaviorVascular 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]
Plant MethodsBackground 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).

Coordination Between Phloem Loading and Structure Maintains Carbon Transport Under Drought
Frontiers 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.

A Proposed Drought Response Equation Added to the Münch-Horwitz Theory of Phloem Transport [PDF]
Frontiers 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]
F1000Research, 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]
Journal 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.

Frontiers in Plant Science, 2013 The pressure flow model of phloem transport envisaged by Münch (1930) has gained wide acceptance. Recently, however, the model has been questioned on structural and physiological grounds.

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

Scaling of xylem and phloem transport capacity and resource usage with tree size
Frontiers in Plant Science, 2013 Xylem and phloem need to maintain steady transport rates of water and carbohydrates to match the exchange rates of these compounds at the leaves. A major proportion of the carbon and nitrogen assimilated by a tree is allocated to the construction and ...

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]
PLoS 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
