Figure 1: Passive phloem loading in plants and in the synthetic tree-on-a-chip. Using our synthetic passive loader, we study in this paper the full dynamics of passive phloem loading, set by the ...

Careful cutting of the hypocotyl of Ricinus communis L. seedlings led to the exudation of pure sieve-tube sap for 2—3 h. This offered the possibility of testing the phloem-loading system qualitatively ...

We have investigated the consequences of endogenous limitations in oxygen delivery for phloem transport in Ricinus communis. In situ oxygen profiles were measured directly across stems of plants ...

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 ...
