Table I. Identified differentially regulated phosphopeptides normalized by proteins in both experiments.
Peptides sequences are listed in peptide ID; capital letters in the peptide sequence column indicate amino acids; lowercase p indicates phosphorylation of the serine, threonine, or tyrosine residue that follows, and (ox) indicates oxidation of the methionine that follows. The average of auxin to control ratio, standard deviation (STD), and p value are listed for each differentially regulated peptide. The AG code and description of the proteins are listed.
