The essential amino acid lysine is synthesised in higher plants via a pathway starting with
aspartate, that also leads to the formation of threonine, methionine and isoleucine. Enzyme …

Lysine is the main limiting essential amino acid (EAA) in the rice seeds, which is a major
energy and nutrition source for humans and livestock. In higher plants, the rate‐limiting …

Amino acid metabolism is a fundamental process for plant growth and development.
Although a considerable amount of information is available, little is known about the genetic …

Quality protein maize (QPM) varieties have been produced by the introduction of opaque-2
modifier genes. Two QPM varieties, BR451 and BR473, a wild type and an opaque-2 …

Two high lysine maize endosperm mutations, opaque-5 (o5) and opaque-7 (o7), were
biochemically characterized for endosperm protein synthesis and lysine metabolism in …

In plant, the first and the third steps of the synthesis of methionine and threonine are
catalyzed by a bifunctional enzyme, aspartate kinase-homoserine dehydrogenase (AK …

Abstract Aspartate kinase (AK, EC 2.7. 2.4) and homoserine dehydrogenase (HSDH, EC 1.1.
1.3) have been partially purified and characterised from immature sorghum seeds. Two …

The capacity of three maize endosperm opaque mutants (o10, o11 and o13) to accumulate
soluble lysine in the seed in relation to their wildtype counterpart, W22+, was investigated …

In plant and microorganisms, aspartate semialdehyde dehydrogenase (ASDH) produces the
branch point intermediate between the lysine and threonine/methionine pathways. In this …

Nitrogen is an essential primary nutrient for plant growth and development. With the demand
for high growth and yield of plants and the depletion of organics in soil, nitrogen availability …
