To protect against loss of photo-assimilate-rich phloem sap, plants have evolved several mechanisms to plug phloem sieve tubes in response to damage. In many Fabaceae, each sieve element contains a ...

A mathematical model of water and sucrose transport across the sieve tube boundary is presented, based on conservation of matter and the phenomenological equations for plasmodesmatal transport between ...

Researchers have combined traditional genetic approaches with 3-D reconstructions from scanning electron microscopy to discover and characterize genes regulating the development of plant sieve ...

In vascular plants, long-distance transport of photoassimilates is driven by a pressure gradient within the phloem. It is a highly specialised tissue consisting of a network of living, tube-shaped ...
