Small peptides, big importance: Small, secreted peptides as novel regulators of symbiosis and nutrient acquisition
Blog, Plant Science Research Weekly, Research, Research BlogIt is becoming increasingly evident that small, secreted peptides (SSPs) are important regulators of plant development and responses to stress. Traditional gene prediction algorithms are biased toward larger coding sequences and have therefore been inadequate in the hunt for plant SSPs. To address this…
Identification of novel growth regulators in plant populations expressing random peptides

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…
