It is generally believed that an osmotically generated pressure gradient drives the phloem
mass flow. So far, this widely accepted Münch theory has required remarkably few …

▪ Abstract The transport events from the sieve elements to the sites of utilization within the
recipient sink cells contribute to phloem unloading. The phenomenon links sink metabolism …

Each perennial woody plant is a highly integrated system of competing carbohydrate sinks
(utilization sites). Internal competition for carbohydrates is shown by changes in rates of …

This review reports on the processes associated with carbon transfer and metabolism in
leaves and growing organs and the role of long‐distance transport and vascular links in the …

This review deals with aspects of the cellular and molecular biology of the sieve
element/companion cell complex, the functional unit of sieve tubes in angiosperms. It …

Amino acid transporters are the main mediators of nitrogen distribution throughout the plant
body, and are essential for sustaining growth and development. In this review, we …

Plant growth, productivity, and seed yield depend on the efficient uptake, metabolism, and
allocation of nutrients. Nitrogen is an essential macronutrient needed in high amounts …

In terrestrial higher plants, phloem transport delivers most nutrients required for growth and
storage processes. Some 90% of plant biomass, transported as sugars and amino nitrogen …

Maternal-to-filial nutrition transfer is central to grain development and yield. nitrate
transporter 1/peptide transporter (NRT1-PTR)-type transporters typically transport nitrate …

Current concepts of the factors determining sink strength and the subsequent regulation of
carbohydrate metabolism in tomato fruit are based upon an understanding of the relative …
