The phloem of higher plants translocates a diverse range of macromolecules including proteins, RNAs, and pathogens. This review considers the origin and destination of such macromolecules. A survey of the literature reveals that the majority of [...]article/chapitre/communication
The toxic heavy metal cadmium is taken up by plants and may contaminate harvested parts of agricultural crops. In the experiments reported here, cadmium was introduced together with markers for phloem (rubidium) and xylem (strontium) transport, [...]article/chapitre/communication
A. Jamai ; M. Laloi ; A. Bourbouloux ; M. Valantin ; S. Delrot | 1996Uptake of the dipeptide [H-3]Leu-Leu into leaf discs from mature broad bean (Vicia faba L.) was characterized. Uptake was maximal at p H 6.0 and appeared to be mediated by three systems with apparent K-m values of 20 mu M, 350 mu M and 43 m M, r[...]article/chapitre/communication
The role of interspecific interactions among herbivorous insects is considered to be limited, especially in specialist communities. In the current study we report on exploitative interspecific interaction between two closely related phloem-feedi[...]article/chapitre/communication
