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 most plant species, amino acids are the predominant chemical forms in which nitrogen is
transported. However, in nodulated tropical or subtropical legumes, ureides are the main …

Legume plants from Fabaceae family (phylogenetic group composed by three subfamilies:
Caesalpinioideae, Mimosoideae, and Papilionoideae) can fix atmospheric nitrogen (N 2) …

The embryo of Arabidopsis seeds is symplasmically isolated from the surrounding seed coat
and endosperm, and uptake of nutrients from the seed apoplast is required for embryo …

Background Amino acid transporters (AATs) that transport amino acids across cellular
membranes are essential for plant growth and development. To date, a genome-wide …

Background Amino acids, which are transported by amino acid transporters, are the major
forms of organic nitrogen utilized by higher plants. Among the 19 Amino Acid Permease …

The development of sink organs such as fruits and seeds strongly depends on the amount of
nitrogen that is moved within the phloem from photosynthetic‐active source leaves to the …

Seed development largely depends on the long‐distance transport of sucrose from
photosynthetically active source leaves to seed sinks. This source‐to‐sink carbon allocation …
