Post-phloem transport: principles and problems

Journal of Experimental Botany, 1996
The movement of assimilates from the sieve element/companion cell complex to sites of utilization has been examined in an extensive array of sinks possessing diverse anatomies. This work has been reviewed with respect to the pathways taken, the conductances and driving forces for movement along the pathways, and interaction between the apoplast and ...

Effect of Low Light Stress on Distribution of Auxin (Indole-3-acetic Acid) between Shoot and Roots and Development of Lateral Roots in Barley Plants

Biology, 2023
Depending on their habitat conditions, plants can greatly change the growth rate of their roots. However, the mechanisms of such responses remain insufficiently clear.

Phloem Catastrophe: Using Bifurcation Analysis to Predict Plant Tipping Points

ARC Geophysical Research
A mathematical framework is developed to analyze phloem failure in plants using bifurcation analysis and catastrophe theory. The framework balances sucrose production from leaf photosynthesis modeled using stomatal optimality theory with sucrose ...

Monitoring Phloem Unloading and Post-Phloem Transport by Microperfusion of Attached Wheat Grains [PDF]

Plant Physiology, 1994
Phloem unloading and post-phloem transport in developing wheat (Triticum aestivum L.) grains were investigated by perfusing the endosperm cavities of attached grains. Relative unloading ratio (RUR) and the rate of sucrose release into the endosperm cavity (SRR) were calculated, respectively, from 14C import and from sucrose washout from the cavity. RUR

Comparative Transcriptional and Anatomical Analyses of Tolerant Rough Lemon and Susceptible Sweet Orange in Response to ‘Candidatus Liberibacter asiaticus’ Infection

Molecular Plant-Microbe Interactions, 2012
Although there are no known sources of genetic resistance, some Citrus spp. are reportedly tolerant to huanglongbing (HLB), presumably caused by ‘Candidatus Liberibacter asiaticus’.

Facilitating Phloem-Mediated Iron Transport Can Improve the Adaptation of Rice Seedlings to Iron Deficiency Stress

Rice
Iron (Fe) is essential for normal plant growth and development. In rice, Fe deficiency leads to stunted growth, leaf chlorosis, reduced photosynthetic capacity, and ultimately, yield loss.

Hydrodynamics of steady state phloem transport with radial leakage of solute

Frontiers in Plant Science, 2013
Long-distance phloem transport occurs under a pressure gradient generated by the osmotic exchange of water associated with solute exchange in source and sink regions.

Callose deposited at soybean sieve element inhibits long-distance transport of Soybean mosaic virus

AMB Express, 2022
The function of callose and its deposition characteristics at phloem in the resistance to the long-distance transportation of Soybean mosaic virus (SMV) through phloem was studied.

Effects of PEG-Induced Water Deficit in Solanum nigrum on Zn and Ni Uptake and Translocation in Split Root Systems

Plants, 2015
Drought strongly influences root activities in crop plants and weeds. This paper is focused on the performance of the heavy metal accumulator Solanum nigrum, a plant which might be helpful for phytoremediation.

Quantifying the Capacity of Phloem Loading in Leaf Disks with [14C]Sucrose

Bio-Protocol, 2017
Phloem loading and transport of photoassimilate from photoautotrophic source leaves to heterotrophic sink organs are essential physiological processes that help the disparate organs of a plant function as a single, unified organism.
