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

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.

The Role of Phloem Loading Reconsidered [PDF]

open access: yesPlant Physiology, 2010
It is generally assumed that the primary role of phloem loading is to drive long-distance transport by elevating hydrostatic pressure in sieve elements. This concept is consistent with the fact that, in many plants, energy is used to increase the concentrations of photoassimilates in the leaf ...

Sugar metabolism and accumulation in the fruit of transgenic apple trees with decreased sorbitol synthesis. [PDF]

open access: yes, 2018
Both sorbitol and sucrose are synthesized in source leaves and transported to fruit for supporting fruit growth in tree fruit species of the Rosaceae family.

Phaseolus vulgaris SUT1.1 is a high affinity sucrose‐proton co‐transporter

open access: yesPlant Direct, 2020
Plant sucrose transporters are required for phloem loading, and therefore are essential for plant growth and development. In common beans (Phaseolus vulgaris) there are only two sucrose transporters functionally characterized.

Transcriptional regulation of the raffinose family oligosaccharides pathway in Sorghum bicolor reveals potential roles in leaf sucrose transport and stem sucrose accumulation

open access: yesFrontiers in Plant Science, 2022
Bioenergy sorghum hybrids are being developed with enhanced drought tolerance and high levels of stem sugars. Raffinose family oligosaccharides (RFOs) contribute to plant environmental stress tolerance, sugar storage, transport, and signaling.

Leaf-applied sodium chloride promotes cadmium accumulation in durum wheat grain [PDF]

open access: yes, 2007
Cadmium (Cd) accumulation in durum wheat grain is a growing concern. Among the factors affecting Cd accumulation in plants, soil chloride (Cl) concentration plays a critical role.

Phloem Loading of Sucrose [PDF]

open access: yesPlant Physiology, 1977
Autoradiographic, plasmolysis, and (14)C-metabolite distribution studies indicate that the majority of exogenously supplied (14)C-sucrose enters the phloem directly from the apoplast in source leaf discs of Beta vulgaris. Phloem loading of sucrose is pH-dependent, being markedly inhibited at an apoplast pH of 8 compared to pH 5.

Phloem Loading through Plasmodesmata: A Biophysical Analysis

open access: yesPlant Physiology, 2017
In many species, sucrose en route out of the leaf migrates from photosynthetically active mesophyll cells into the phloem down its concentration gradient via plasmodesmata, i.e., symplastically. In some of these plants the process is entirely passive, but in others phloem sucrose is actively converted into larger sugars, raffinose and stachyose, and ...

An RNAi-Based Control of Fusarium graminearum Infections Through Spraying of Long dsRNAs Involves a Plant Passage and Is Controlled by the Fungal Silencing Machinery [PDF]

open access: yes, 2016
Meeting the increasing food and energy demands of a growing population will require the development of ground-breaking strategies that promote sustainable plant production.

Heavy Metals in Crop Plants: Transport and Redistribution Processes on the Whole Plant Level

open access: yesAgronomy, 2015
Copper, zinc, manganese, iron, nickel and molybdenum are essential micronutrients for plants. However, when present in excess they may damage the plant or decrease the quality of harvested plant products.
