Knowing that many small molecules act as growth regulators, chemical genomics endeavors to identify novel growth-regulating compounds through screening thousands of randomly generated molecules. Knowing that many peptides also act as growth regulators, Bao et al. used a similar approach to look for novel…
Shoot-to-root mobile polypeptides involved in systemic regulation of nitrogen acquisition ($)
Plant Science Research Weekly, ResearchTo balance nutrient uptake (usually from heterogeneous sources) with nutrient demand, plants use a root-shoot-root signaling pathway. Previously, a root-to-shoot mobile peptide C-TERMINALLY ENCODED PEPTIDE (CEP) was shown to translocate from N-starved roots to the shoot, where it interacts with a leucine-rich…
