Plants in nature are constantly exposed to organisms that touch them and wound them. A
highly conserved response to these stimuli is a rapid collapse of membrane potential (ie a …

Dodders (Cuscuta spp.) are obligate parasitic plants that obtain water and nutrients from the
stems of host plants via specialized feeding structures called haustoria. Dodder haustoria …

Aphids are amongst the most damaging pests of plants that use their stylets to penetrate the
plant tissue to consume large amounts of phloem sap and thus deprive the plant of …

Seed and fruit set are established during and soon after fertilization and determine seed and
fruit number, their final size and, hence, yield potential. These processes are highly sensitive …

In plants, a complex mixture of solutes and macromolecules is transported by the phloem.
Here, we examined how solutes and macromolecules are separated when they exit the …

The leaf veins of higher plants contain a highly specialized vascular system comprised of
xylem and phloem cells that transport water, organic compounds and mineral nutrients. The …

Green plants are Earth's primary solar energy collectors. They harvest the energy of the Sun
by converting light energy into chemical energy stored in the bonds of sugar molecules. A …

Despite the crucial role of carbon transport in whole plant physiology and its impact on plant–
environment interactions and ecosystem function, relatively little research has tried to …

Due to the high content of nutrient, sieve tubes are a primary target for pests, eg, most
phytophagous hemipteran. To protect the integrity of the sieve tubes as well as their content …
