Phosphoproteomics of CEP5 peptide treatment Arabidopsis

ABSTRACT: While CEP5 has been shown to play a role in shoot and root growth, possibly through interaction with the CEPR1/XIP1 and/or CEPR2 receptor kinase, very little is known about the downstream molecular effects. To gain insight in the changes downstream of CEP5, we quantified differences in phosphoproteomes of peptide treatment seedlings using label-free mass spectrometry-based proteomics

Peptides derived from non-functional precursors play important roles in various developmental processes, but also in (a)biotic stress signaling. Our (phospho)proteome-wide analyses of C-TERMINALLY ENCODED PEPTIDE 5 (CEP5)-mediated changes revealed an impact on abiotic stress-related processes. Drought has a dramatic impact on plant growth, development and reproduction, and the plant hormone auxin plays a role in drought responses. Our genetic, physiological, biochemical, and pharmacological resu  ...[more]
