Mechanisms of phloem loading

Current Opinion in Plant Biology, 2018
The complex form of higher plants requires continuous, balanced transport of nutrients in the phloem. The initial step of transferring sugars, amino acids, and other materials from photosynthetic cells to the conducting sieve tubes is known as phloem loading. Three phloem loading mechanisms have been described.

Assessing Rates of Long-distance Carbon Transport in Arabidopsis by Collecting Phloem Exudations into EDTA Solutions after Photosynthetic Labeling with [14C]CO2

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.

AtABCG14: A Long-Distance Root-to-Shoot Carrier of Cytokinin

International Journal of Plant Biology, 2022
Root-synthesized cytokinins regulate the growth, development, and stress responses of aboveground tissues and follow the transport route via xylem tissue. Arabidopsis ATP-binding cassette (ABC) transporter G family member 14 (AtABCG14) is involved in the

Changes in the Elemental and Metabolite Profile of Wheat Phloem Sap during Grain Filling Indicate a Dynamic between Plant Maturity and Time of Day

Metabolites, 2018
The long distance transport of Fe and Zn in the phloem sap of wheat (Triticum aestivum L.) is the key route for seed supply, due to wheat having a xylem discontinuity.

Effect of stem age on the response of stem diameter variations to plant water status in tomato [PDF]

, 2012
Plant water status plays a major role in glasshouse cultivation of tomato (Solanum lycopersicum L.). New climate control technologies alter the glasshouse climate and make it less dependent on solar radiation.

Amino Acid Transporters in Plant Cells: A Brief Review

Plants, 2020
Amino acids are not only a nitrogen source that can be directly absorbed by plants, but also the major transport form of organic nitrogen in plants. A large number of amino acid transporters have been identified in different plant species.

Differential Effects of Senescence on the Phloem Exports of Cadmium and Zinc from Leaves to Grains in Rice during Grain Filling

Plants, 2023
In rice, non-essential toxic cadmium (Cd) and the essential nutrient zinc (Zn) share similar transport pathways, which makes it challenging to differentially regulate the allocation of these elements to the grain.

Extraction of Apoplastic Wash Fluids and Leaf Petiole Exudates from Leaves of Arabidopsis thaliana

Bio-Protocol, 2015
The long-distance translocation of metabolites and mineral elements is crucial for plant growth and reproduction. In most cases, source-to-sink translocation of metabolites and minerals requires their passage through the apoplast, irrespective whether ...

Role of magnesium in carbon partitioning and alleviating photooxidative damage [PDF]

, 2008
Magnesium (Mg) deficiency exerts a major influence on the partitioning of drymatter and carbohydrates between shoots and roots. One of the very early reactions of plants to Mg deficiency stress is themarked increase in the shootto- root dry weight ...
