Panagiotis Sainatoudis began to get involved in traditional seeds in January 1991 when he organised the first group for the collection, preservation and spreading of traditional seeds in Greece.
He travelled on foot and also hitch hiked over a large area of the country searching for farmers who saved their own seeds. In the span of five years he collected 1200 species of traditional seeds.
In 1995 he organised the first seed sharing event in Greece. In 1999 he organised the first Public Traditional Seed Exchange event and that is the first Seed Exchange event not only in Greece but also in Europe. In 2013 the Australian seed savers characterized the Peliti Seed Festival “The largest Seed Exchange in the World”
In 2017 he started organizing the Olympic Seed Festival. On the 22nd of May 2009 he was honoured as «Guardian of the Mediterranean Biodiversity» by the General Secretary of Biodiversity International and and the mayor of Rome.
In 2013 Peliti received an award for its volunteer work in the country from the President of the Republic of Greece Mr Karolos Papoulias.
