摘要: In plants, phloem loading can occur by a number of mechanisms, including active sugar loading. Passive phloem loading, through the symplasm, has been proposed as the mechanism operating in many trees. Here, current evidence is evaluated regarding this loading mechanism, and the potential influence of protein-mediated sugar transport and regulation of cell coupling is discussed.
