Nitrogen is a limiting resource for plant growth in most terrestrial habitats since large
amounts of nitrogen are needed to synthesize nucleic acids and proteins. Among the 21 …

The respiratory pathways of glycolysis, the tricarboxylic acid (TCA) cycle and the
mitochondrial electron transport chain are ubiquitous throughout nature. They are essential …

Mitochondrial respiration in plants provides energy for biosynthesis, and its balance with
photosynthesis determines the rate of plant biomass accumulation. We describe recent …

Mitochondrial carriers (MCs) are a superfamily of nuclear-encoded proteins that are mostly
localized in the inner mitochondrial membrane and transport numerous metabolites …

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 …

Nitrogen is an essential macronutrient for plant growth. Following uptake from the soil or
assimilation within the plant, organic nitrogen compounds are transported between …

Membrane proteins are essential to move amino acids in or out of plant cells as well as
between organelles. While many putative amino acid transporters have been identified …

Arabidopsis genes encoding enzymes for each of the eight steps in l-arginine (Arg)
synthesis were identified, based upon sequence homologies with orthologs from other …

Non-protein amino acids are a significant store of organic nitrogen in many ecosystems, but
there is a lack of knowledge relating to them. Research has indicated that they play …

Background Like many other plant species, Arabidopsis uses arginine (Arg) as a storage
and transport form of nitrogen, and proline (Pro) as a compatible solute in the defence …
