Title	Exo-proteomics analysis in the microbial antagonist Pythium oligandrum cultured with inactivated oomycete mycelial powder
Description	Pythium oligandrum is an important microbial antagonist and biocontrol agent. P. oligandrum protease activity was found to be induced when cultured with inactivated oomycete mycelial powder from one of its hosts/prey Pythium myriotylum. The dataset consists of exo-proteomics analysis of culture supernatants from 2 d P. oligandrum GAQ1 strain shake-flask cultures with Plich medium supplemented with either glucose (samples GAQ1G-L4 to 6) or inactivated mycelial powder (samples GAQ1P-L7 to 9). A total of 453 proteins or protein groups were detected in at least one of the culture supernatants, each with at least two unique peptides. There were 91 proteins more abundant or exclusively detected in the mycelial powder cultures, and 96 proteins more abundant or exclusively detected in the glucose cultures. Proteases were among the most common annotations among proteins more abundant in mycelial powder cultures. The dataset highlights proteins potentially involved in P. oligandrum antagonism and in the utilization of carbon and nitrogen sources.
