Cellular and whole organism iron homeostasis must be balanced to supply enough iron for
metabolism and to avoid excessive, toxic levels. To perform iron uptake from the …

▪ Abstract Nitrate is the major source of nitrogen (N) for plants growing in aerobic soils.
However, the NO3− ion is also used by plants as a signal to reprogram plant metabolism …

The concept that proteins and small RNAs can move to and function in distant body parts is
well established. However, non-cell-autonomy of small RNA molecules raises the question …

Recent studies have revealed the operation of a long-distance communication network
operating within the vascular system of higher plants. The evolutionary development of this …

Metal transporters are a central component in the interaction of algae with their environment.
They represent the first line of defense to cellular perturbations in metal concentration, and …

The evolution of intercellular communication had an important role in the increasing
complexity of both multicellular and supracellular organisms. Plasmodesmata, the …

Root system formation proceeds in close coordination with shoot growth. Accordingly, root
growth and its functions are regulated tightly by the shoot through materials cycling between …

The phloem translocation stream contains a population of RNA molecules, suggesting
plants use RNA to integrate developmental processes, at the whole‐plant level. In the …

Many different proteins can be separated from the sap of mature sieve tubes of different
plant species. To date, only a limited number of those have been identified and functionally …

Increasing evidence suggests that proteins present in the angiosperm sieve tube system
play an important role in the long distance signaling system of plants. To identify the nature …
