In this diagram of G-protein-coupled receptor activation, the alpha, beta, and gamma subunits are shown with distinct relationships to the plasma membrane. After exchange of GDP with GTP on the alpha ...

This is a representation of a G protein alpha subunit after the beta-gamma pair dissociated. The blue patches represent the places where alpha and beta-gamma were previously attached. Disclaimer: AAAS ...

Journal of Experimental Botany, Vol. 67, No. 11 (2016), pp. 3433-3443 (11 pages) Essential in the Green Revolution was the development of high-yielding dwarf varieties of rice (Oryza sativa L.), but ...

Different classes of biotic (e.g. plant hormones) and abiotic (e.g. different wavelengths of light) signals act through specific signal transduction mechanisms to coordinate higher plant development.

The research team has found that GS3 forms molecular clusters (oligomers) through disulfide bonds—a chemical linkage between sulfur atoms in proteins. These clusters diminish GS3's capacity to ...
