Long-distance solute transport in trees improved by intercellular pathways in living woody tissues

As large organisms, trees face some remarkable challenges, particularly regarding long-distance transport and communication. In addition to moving water and nutrients from their roots to their leaves, they must also integrate cell-to-cell communication over large areas. Furthermore, in order to function as a single, cohesive organism they must be able to effectively and efficiently send vital substances—such as DNA regulating signals—long distances along a network of cells, sieve-tubes, and vessels.
