Table_1_Coordination Between Phloem Loading and Structure Maintains Carbon Transport Under Drought.DOCX

open access: yes, 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.

Chitosan‐Carbon Dot Composite Materials Form a Leaf Surface Barrier to Mitigate the Enrichment and Invasion of Nanoplastics: From Leaf Interface to Systemic Response

open access: yesAdvanced Science, EarlyView.
Foliar spraying of CS‐CDs can form a film on the leaves of Brassica rapa, effectively reducing the enrichment and absorption of PS in the leaves, while increasing the biomass and nutrient content of the plants. In addition, CS‐CDs can also enrich the interfoliar microbial community and activate the plant's own defense metabolic pathways.

Pectin Metabolism Influences Phloem Architecture and Flowering Time in Arabidopsis Thaliana

open access: yesAdvanced Science
Cell wall matrices undergo continuous remodeling during plant growth and development. The methyl‐ and de‐methyl‐esterification of pectic homogalacturonan dynamically influence the physicochemical and mechanical properties of cell walls, and consequently ...

Cotton Recruits Soil‐Derived Delftia tsuruhatensis to Suppress Aphid Detoxification Via Salicylic Acid‐Mediated Defense

open access: yesAdvanced Science, EarlyView.
This study systematically reveals a complex interactive network involving plants, microbes, and insects, elucidating the ecological and molecular mechanisms by which cotton enhances its resistance to aphids through the active recruitment of the beneficial soil bacterium Delftia tsuruhatensis.

Passive phloem loading and long-distance transport in a synthetic tree-on-a-chip [PDF]

open access: yes, 2020
© 2017 Macmillan Publishers Limited, part of Springer Nature. All rights reserved. Vascular plants rely on differences in osmotic pressure to export sugars from regions of synthesis (mature leaves) to sugar sinks (roots, fruits).

Phloem translocation of strong acids - glyphosate, substituted phosphonic and sulfonic acids - in Ricinus communis L

open access: yes, 1993
The mobility in phloem of several substituted phosphonic acids and a sulfonic acid was studied in the castor bean plant, Ricinus communis L. For a series of C-14-labelled phosphonate mono-esters applied to the petioles of mature leaves, phloem transport ...

From Defense Executor to Engineering Target: Harnessing Lignin for Crop Resistance

open access: yesAdvanced Science, EarlyView.
Lignin serves as both a physical and chemical executor of broad‐spectrum plant immunity. This review systematically summarizes classical and recent advances in lignin‐mediated immunity, outlines the multifaceted regulatory modules controlling lignification under biotic stress, discusses key physiological and biochemical mechanisms behind lignin‐based ...

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

open access: yesBiology, 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.

Drought impacts on phloem transport

open access: yesCurrent Opinion in Plant Biology, 2018
Drought impacts on phloem transport have attracted attention only recently, despite the well-established, and empirically verified theories on drought impacts on water transport in plants in general. This is because studying phloem transport is challenging. Phloem tissue is relatively small and delicate, and it has often been assumed not to be impacted

Solution-Flow in the Phloem [PDF]

open access: yesPlant Physiology, 1972
Translocation profiles along the path were studied using a modified flap-feeding technique for the simultaneous application of THO and (14)C-sucrose. A re-evaluation of a mathematical model for phloem transport with reversible lateral exchange of tracer along the path indicates that lower apparent velocities for THO as compared to labeled carbohydrate ...
