For organisms to coordinate their growth and development with nutrient availability, they must be able to sense nutrient levels in their environment. Here, we review select nutrient-sensing mechanisms in a few diverse organisms. We discuss how these mechanisms reflect the nutrient requirements of specific species and how they have adapted to the emergence of multicellularity in eukaryotes.

In South Africa during the past four decades considerable research has taken place on the nutrient requirements of sugarcane. Consequently marked changes have occurred in patterns of fertilizer use. The value of N, P and K fertil~zers for cane production is reviewed using field experimental data. Correlations established between soil and leaf analysis and crop responses to various nutrients are...

Abstract Since 1944, there have been 11 editions of the Nutrient Requirements Swine coordinated by National Research Council (NRC; currently Academies Sciences, Medicine and Engineering [NASEM]) published Academy Press. Between 1944 1988 were 9 3 between 2022. The description nutrient requirements for swine has refined augmented to reflect modern pig genetics expanding methodology measure perfo...
