Structural and functional heterogeneity in phloem loading and transport [PDF]
Frontiers in Plant Science, 2013 The phloem is often regarded as a relatively straightforward transport system composed of loading (collection), long-distance (transport) and unloading zones.

Coordination Between Phloem Loading and Structure Maintains Carbon Transport Under Drought [PDF]
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.

11C-Autoradiographs to Image Phloem Loading [PDF]
Frontiers in Forests and Global Change, 2019 Generally, tree species load photoassimilates passively into the phloem, while herbaceous species load actively. These phloem loading strategies have implications for phloem sugar concentration and growth potential.

Synthesis of Novel Amino Acid–Fipronil Conjugates and Study on Their Phloem Loading Mechanism [PDF]
Molecules, 2018 To develop a new pesticide with phloem mobility, a series of new amino acid–fipronil conjugates were designed and synthesized based on derivatization at the 3-position of the pyrazole ring of fipronil. Experiments using a Ricinus communis seedling system

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

A comprehensive picture of phloem loading strategies [PDF]
Proceedings of the National Academy of Sciences of the United States of America, 2009 Mechanisms of phloem loading in the minor veins of leaves are known for only a few species. We propose that there are a limited number of loading strategies for the primary photoassimilates, sucrose and sugar alcohols. These strategies can be predicted based on thermodynamic and anatomical considerations and identified by ...

Adaptive responses to elevated CO2 in fruit species with different phloem loading mechanisms [PDF]
Frontiers in Plant ScienceIntroductionIt has been suggested that the mechanism of phloem loading, that is apoplastic or symplastic loading, may affect a plant’s ability to adapt to elevated CO2 levels.

Maize SUT1 functions in phloem loading. [PDF]
Plant Signal Behav, 2010 The functions of dicot sucrose transporters (SUTs) in apoplastic phloem loading of sucrose are well established; however, whether SUTs similarly function in monocots was unresolved. To address this question, we recently provided genetic evidence that ZmSUT1 from maize (Zea mays) is required for efficient phloem loading.

The mechanism of phloem loading in rice (Oryza sativa). [PDF]
Mol Cells, 2012 Carbohydrates, mainly sucrose, that are synthesized in source organs are transported to sink organs to support growth and development. Phloem loading of sucrose is a crucial step that drives long-distance transport by elevating hydrostatic pressure in the phloem.

Regulated to respond: dual localization and dynamic control of AVP1 in plant carbon partitioning [PDF]
Frontiers in Plant ScienceArabidopsis Vacuolar Pyrophosphatase 1 (AVP1), a conserved type I proton-pumping pyrophosphatase (H+-PPase), was characterized as tonoplast localized with a role in acidifying the lumen and removing cytosolic pyrophosphate (PPi), a byproduct of ...
