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 ...

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 and drought [PDF]

open access: yesJournal of Experimental Botany, 2014
Drought challenges plant water uptake and the vascular system. In the xylem it causes embolism that impairs water transport from the soil to the leaves and, if uncontrolled, may even lead to plant mortality via hydraulic failure. What happens in the phloem, however, is less clear because measuring phloem transport is still a significant challenge to ...

Pectin Metabolism Influences Phloem Architecture and Flowering Time in Arabidopsis Thaliana [PDF]

open access: yesAdvanced Science
Cell wall matrices undergo continuous remodeling during plant growth and development. The methyl‐ and de‐methyl‐esterification of pectic homogalacturonan dynamically influence the physicochemical and mechanical properties of cell walls, and consequently ...

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.

Phloem transport of flowering signals [PDF]

open access: yesCurrent Opinion in Plant Biology, 2008
Seasonal variability in environmental parameters such as day length regulates many aspects of plant development. The transition from vegetative growth to flowering in Arabidopsis is regulated by seasonal changes in day length through a genetically defined molecular cascade known as the photoperiod pathway. Recent advances were made in understanding the

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

Potential Involvement of a Cucumber Homolog of Phloem Protein 1 in the Long-Distance Movement of Cucumber mosaic virus Particles

open access: yesMolecular Plant-Microbe Interactions, 2006
The systemic movement of Cucumber mosaic virus (CMV) in cucumber plants was analyzed. The structure that is translocated and its putative interactions with phloem components were analyzed in phloem exudate (PE) samples, which reflect sieve tubes stream ...

Does Don Fisher’s high-pressure manifold model account for phloem transport and resource partitioning?

open access: yesFrontiers 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.
