A Phloem-Expressed PECTATE LYASE-LIKE Gene Promotes Cambium and Xylem Development

open access: yesFrontiers in Plant Science, 2022
The plant vasculature plays essential roles in the transport of water and nutrients and is composed of xylem and phloem, both of which originate from undifferentiated cells found in the cambium.

Geochemical support for a climbing habit within the Paleozoic seed fern genus Medullosa [PDF]

open access: yes, 2011
A long-standing problem in paleobotany is the accurate identification of the growth habits and statures of fossil plants. Tissue-specific analysis of stable carbon isotope ratios in plant fossils can provide an independent perspective on this issue ...

The ferroxidases are critical for Fe(II) oxidation in xylem to ensure a healthy Fe allocation in Arabidopsis thaliana

open access: yesFrontiers in Plant Science, 2022
The long-distance transport of iron (Fe) in the xylem is critical for maintaining systemic Fe homeostasis in plants. The loading form of Fe(II) into the xylem and the long-distance translocation form of Fe(III)–citrate have been identified, but how Fe(II)

Causes of Quality Loss of Cut Flowers - A Critical Analysis of Post-Harvest Treatments [PDF]

open access: yes, 2009
Temperature is one of the most important factors in the postharvest phase to control quality losses, yet temperature is still poorly managed, partly because its effects are not always understood well.

Investigating Effects of Bordered Pit Membrane Morphology and Properties on Plant Xylem Hydraulic Functions—A Case Study from 3D Reconstruction and Microflow Modelling of Pit Membranes in Angiosperm Xylem

open access: yesPlants, 2020
Pit membranes in between neighboring conduits of xylem play a crucial role in plant water transport. In this review, the morphological characteristics, chemical composition and mechanical properties of bordered pit membranes were summarized and linked ...

The watering of tall trees - Embolization and recovery [PDF]

open access: yes, 2015
We can propound a thermo-mechanical understanding of the ascent of sap to the top of tall trees thanks to a comparison between experiments associated with the cohesion-tension theory and the disjoining pressure concept for liquid thin-films.

Investigating water transport through the xylem network in vascular plants [PDF]

open access: yesJournal of Experimental Botany, 2014
Our understanding of physical and physiological mechanisms depends on the development of advanced technologies and tools to prove or re-evaluate established theories, and test new hypotheses. Water flow in land plants is a fascinating phenomenon, a vital component of the water cycle, and essential for life on Earth.

Mechanisms of manganese uptake and long-distance transport in the hyperaccumulator Celosia argentea Linn.

open access: yesEcotoxicology and Environmental Safety
Celosia argentea Linn. is a hyperaccumulator for the remediation of manganese (Mn)-contaminated soil owing to its rapid growth, high decontamination capacity, and strong stress resistance.

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

open access: yes, 2017
Vascular plants rely on differences of osmotic pressure to export sugars from regions of synthesis (mature leaves) to sugar sinks (roots, fruits). In this process, known as M\"unch pressure flow, the loading of sugars from photosynthetic cells to the ...
