Uptake and transport of antibiotic kasugamycin in castor bean (Ricinus communis L.) seedlings

Frontiers in Microbiology, 2022
Kasugamycin (KSM), an aminoglycoside antibiotic, has been widely used for the management of plant diseases, especially for the control of rice blast in Asia. However, its uptake mechanism and transport in plants are still obscure.

Phloem RNA-binding proteins as potential components of the long-distance RNA transport system.

Frontiers in Plant Science, 2013
RNA-binding proteins (RBPs) govern a myriad of different essential processes in eukaryotic cells. Recent evidence reveals that apart from playing critical roles in RNA metabolism and RNA transport, RBPs perform a key function in plant adaption to various

OBERON3 and SUPPRESSOR OF MAX2 1-LIKE proteins form a regulatory module driving phloem development

Nature Communications, 2023
Spatial specificity of cell fate decisions is central for organismal development. The phloem tissue mediates long-distance transport of energy metabolites along plant bodies and is characterized by an exceptional degree of cellular specialization.

On the Efficacy of Water Transport in Leaves. A Coupled Xylem-Phloem Model of Water and Solute Transport

Frontiers in Plant Science, 2021
In this paper, we present and use a coupled xylem/phloem mathematical model of passive water and solute transport through a reticulated vascular system of an angiosperm leaf.

Linking phloem function to structure: Analysis with a coupled xylem–phloem transport model [PDF]

Journal of Theoretical Biology, 2009
We carried out a theoretical analysis of phloem transport based on Münch hypothesis by developing a coupled xylem-phloem transport model. Results showed that the maximum sugar transport rate of the phloem was limited by solution viscosity and that transport requirements were strongly affected by prevailing xylem water potential.

Radiosynthesis of 6'-Deoxy-6'[18F]Fluorosucrose via Automated Synthesis and Its Utility to Study In Vivo Sucrose Transport in Maize (Zea mays) Leaves.

PLoS ONE, 2015
Sugars produced from photosynthesis in leaves are transported through the phloem tissues within veins and delivered to non-photosynthetic organs, such as roots, stems, flowers, and seeds, to support their growth and/or storage of carbohydrates.

AmSUT1, a Sucrose Transporter in Collection and Transport Phloem of the Putative Symplastic Phloem LoaderAlonsoa meridionalis  [PDF]

Plant Physiology, 2004
AbstractA sucrose (Suc) transporter cDNA has been cloned from Alonsoa meridionalis, a member of the Scrophulariaceae. This plant species has an open minor vein configuration and translocates mainly raffinose and stachyose in addition to Suc in the phloem (C. Knop, O. Voitsekhovskaja, G. Lohaus [2001] Planta 213: 80–91).

Structural and functional heterogeneity in phloem loading and transport

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.

Phloem transport: Are you chaperoned? [PDF]

Current Biology, 1999
Long-distance transport via the vasculature in plants is critical for nutrient dissemination, as well as transport of growth regulatory molecules such as hormones. Evidence is now accumulating that protein and RNA molecules also use this transport pathway, possibly to regulate developmental and physiological processes.

Assessing Long-distance Transport from Photosynthetic Source Leaves to Heterotrophic Sink Organs 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.
