The cambium and its "zone" is a cell generator (reproductive tissue called growth meristem) that produces both the inner bark cells of the phloem and new living wood cells in the xylem. The phloem ...

Specialised plant cells include root hair, palisade, xylem and phloem cells. Find out more with Bitesize. For students between the ages of 11 and 14.

Existing synthetic designs of phloem transport, however, do not reproduce the interactions thought to exist between the phloem tube, the photosynthetic cells and the xylem, and are limited by the ...

In xylem cells the fibers provide strength in the form of wood; the vessels allow water and nutrient flow to the leaves. Cells to the outside make up the phloem, which transports sugars, amino ...

In wild-type roots, cytokinin induces ARR15 in procambial cells, but not in xylem and phloem cells, and ARR16 in the PERICYLCE. Recently, ARR15 was found to function as a repressor of type-B ARRs 55.

However, these diseases can be difficult to study, as phloem cells are relatively inaccessible and difficult to isolate. In work presented in a recent issue of Applications in Plant Sciences, ...
