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 ...

\u3ci\u3eTomicus Piniperda\u3c/i\u3e (Coleoptera: Scolytidae) Reproduction and Development in Scots, Jack, Red and Eastern White Pine Under Laboratory Conditions [PDF]

open access: yes, 2018
The pine shoot beetle, Tomicus piniperda (L.) (Coleoptera: Scolytidae), is an exotic bark beetle in North America that was first found in the Great Lakes region in 1992. We evaluated T.

Sclerification in the bark tissues of common fir (Abies alba Mill.)

open access: yesActa Societatis Botanicorum Poloniae, 2014
The sclerification process in bark tissues of common fir (Abies alba Mill.) has been described. The sclerification begins in 3 years old stems. Sclereids differentiate from cortical parenchyma cells and from secondary phloem parenchyma cells that do not ...

Facile Labeling of Sieve Element Phloem-Protein Bodies Using the Reciprocal Oligosaccharide Probe OGA488

open access: yesFrontiers in Plant Science, 2022
Sieve elements of many angiosperms contain structural phloem proteins (P-proteins) that can interact to create large P-protein bodies. P-protein bodies can occlude sieve plates upon injury but the range of functional and physiological roles of P-proteins

Measurement of sap flow dynamics through the tomato peduncle using a non-invasive sensor based on the heat field deformation method [PDF]

open access: yes, 2013
Recent contradicting evidence on the contributions of xylem and phloem to tomato fruit growth highlights the need for a more thorough insight into the dynamics of sap flow through the tomato peduncle. In fact, knowledge on sap flow dynamics through small

Potential Involvement of a Cucumber Homolog of Phloem Protein 1 in the Long-Distance Movement of Cucumber mosaic virus Particles

open access: yesMolecular Plant-Microbe Interactions, 2006
The systemic movement of Cucumber mosaic virus (CMV) in cucumber plants was analyzed. The structure that is translocated and its putative interactions with phloem components were analyzed in phloem exudate (PE) samples, which reflect sieve tubes stream ...

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.

Phloem unloading in Arabidopsis roots is convective and regulated by the phloem-pole pericycle

open access: yeseLife, 2017
In plants, a complex mixture of solutes and macromolecules is transported by the phloem. Here, we examined how solutes and macromolecules are separated when they exit the phloem during the unloading process.

The Small RNA Component of Arabidopsis thaliana Phloem Sap and Its Response to Iron Deficiency

open access: yesPlants, 2023
In order to discover sRNA that might function during iron deficiency stress, RNA was prepared from phloem exudates of Arabidopsis thaliana, and used for RNA-seq. Bioanalyzer results indicate that abundant RNA from phloem is small in size—less than 200 nt.

Observations of Xyleborus affinis Eichhoff (Coleoptera:Curculionidae:Scolytinae) in Central Michigan [PDF]

open access: yes, 2017
Xyleborus affinis Eichhoff colonized wind thrown timber in the moist floodplain habitats of Central Michigan. Single adult females constructed a complex gallery system consisting of phloem–sapwood interface tunnels and sapwood tunnels.
