Phloem diseases such as citrus greening ... colleagues at the University of Florida Citrus Research and Education Center present a new technique for identifying phloem cells in plant tissue. ...

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

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.

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 ...

Phloem diseases such as citrus greening are one particularly devastating group of plant diseases that have been wreaking economic havoc globally. Skip to content Menu ...

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 ...

One or more companion cells attached to each sieve tube provide this energy. A sieve tube is completely dependent on its companion cell(s). Comparison of transport in the xylem and phloem ...

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 ...

For example, phloem cells called sieve element lack a nucleus and vacuole, but possess parietal mitochondria, so these cells become apparent when tissue is stained with the organelle-specific ...
