RNA Motifs and Modification Involve in RNA Long-Distance Transport in Plants
Frontiers in Cell and Developmental Biology, 2021 A large number of RNA molecules have been found in the phloem of higher plants, and they can be transported to distant organelles through the phloem.

Electrical signalling along the phloem and its physiological responses in the maize leaf
Frontiers in Plant Science, 2013 To elucidate the role of electrical signalling in the phloem of maize the tips of attached leaves were stimulated by chilling and wounding. Two different signals were detected in the phloem at the middle of the leaf using the aphid stylet technique: (i ...

New aspects of phloem-mediated long-distance lipid signaling in plants
Frontiers in Plant Science, 2012 Plants are sessile and cannot move to appropriate hiding places or feeding grounds to escape adverse conditions. As a consequence, they evolved mechanisms to detect changes in their environment, communicate these to different organs, and adjust ...

Engineering Macromolecular Trafficking Into the Citrus Vasculature
Frontiers in Plant Science, 2022 The plant vasculature is a central organ for long-distance transport of nutrients and signaling molecules that coordinate vegetative and reproductive processes, and adaptation response mechanisms to biotic and abiotic stress.

Pectin Metabolism Influences Phloem Architecture and Flowering Time in Arabidopsis Thaliana
Advanced ScienceCell 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 ...

Drought impacts on phloem transport
Current 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]
Plant 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 ...
