Several characteristics of the process of phloem unloading in the seed coat of developing seeds of Vicia faba L. were investigated. Prior to the procedure of measuring the release of solutes by the ...

Premise of research. Secondary phloem produced by a bifacial vascular cambium is the distinctive feature of lignophytes, the group that comprises the seed plants and the progymnosperms. Because ...

Figure 1: Passive phloem loading in plants and in the synthetic tree-on-a-chip. Using our synthetic passive loader, we study in this paper the full dynamics of passive phloem loading, set by the ...

Crops worldwide are increasingly vulnerable to pandemics, as diseases hitch rides on global flows of people and goods, hopping from continent to continent. Phloem diseases such as citrus greening are ...

Numerous insects and pathogens extract nutrients from phloem tissue buried deep inside plants. These phloem-feeding insects and pathogens cause tremendous economic losses worldwide and represent some ...

The Oregon Department of Forestry discovered an emerald ash borer in tree in the parking lot at the David Douglas Aquatics Center in the Hazelwood neighborhood deep in Northeast Portland. Peter Van ...

In vascular plants, long-distance transport of photoassimilates is driven by a pressure gradient within the phloem. It is a highly specialised tissue consisting of a network of living, tube-shaped ...

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