Using our synthetic passive loader, we study in this paper the full dynamics of passive phloem loading, set by the nonlinear interplay between advection out of the phloem and diffusion from the source ...

Phloem diseases, including the economically devastating citrus greening, are particularly difficult to study because phloem cells -- essential for plant nutrient transport -- are difficult to access ...

American Journal of Botany, Vol. 5, No. 7 (Jul., 1918), pp. 347-378 (38 pages) The more important results of this study may be briefly stated as follows: 1. In the woody dicotyledons, there is no ...

Researchers monitored the progression of phloem production over time in field-grown HLB-affected citrus trees to determine how the trees are capable of sustaining new growth. Results showed that new ...

One goes up... and one goes down. I was a college freshman in Botany 101 when I first learned about xylem and phloem, the two transport tissues which carry water and nutrients up and down a tree's ...
