Manganese (Mn) is an important micronutrient for plant growth and development and
sustains metabolic roles within different plant cell compartments. The metal is an essential …

Micronutrients are involved in all metabolic and cellular functions. Plants differ in their need
for micronutrients, and we will focus here only on those elements that are generally …

The functions of iron, manganese, copper, zinc, nickel, molybdenum, boron, and chlorine in
plants are discussed. Iron (Fe) plays a crucial role in redox systems in cells and various …

Urea is a plant metabolite derived either from root uptake or from catabolism of arginine by
arginase. In agriculture, urea is intensively used as a nitrogen fertilizer. Urea nitrogen enters …

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 …

Abstract Calcium (Ca2+) and manganese (Mn2+) are essential elements for plants and have
similar ionic radii and binding coordination. They are assigned specific functions within …

The enzymatic route of purine ring catabolism has recently been completed by the discovery
of several novel enzymes identified through comparative genome analyses. Here, we review …

Purine catabolism is regarded as a housekeeping function that remobilizes nitrogen for plant
growth and development. However, emerging evidence suggests that certain purine …

Allantoin is a metabolic intermediate of purine catabolism that often accumulates in stressed
plants. Recently, we used Arabidopsis knockout mutants (aln) of ALLANTOINASE to show …

Calcium-dependent protein kinases (CDPKs) comprise a family of plant serine/threonine
protein kinases in which the calcium sensing domain and the kinase effector domain are …
