In order to fight the devastation of phloem diseases, researchers must understand in detail the way these pathogens deform the plant phloem cells known as sieve elements and companion cells.

In order to fight the devastation of phloem diseases, researchers must understand in detail the way these pathogens deform the plant phloem cells known as sieve elements and companion cells.

Phloem is the part of the tissue in vascular plants that comprises the sieve elements -- where actual translocation takes place -- and the companion cells as well as the phloem parenchyma cells.

More specifically AtMC3 is found in a particular cell type of the vasculature, called companion cells which are metabolically supporting the main phloem transport cells (sieve elements), as ...

In order to fight the devastation of phloem diseases, researchers must understand in detail the way these pathogens deform the plant phloem cells known as sieve elements and companion cells. Today ...

Companion cells - transport of substances in the phloem requires energy. One or more companion cells attached to each sieve tube provide this energy.

Figure 1: Circadian clock functions in phloem companion cells are necessary for photoperiodic flowering. Figure 2: Circadian clock functions in epidermal cells are necessary for cell elongation ...

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.

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