The Committee has planned a Special Issue covering this conference in the Journal of Plant Physiology (Elsevier, www.journals.elsevier.com/journal-of-plant-physiology) entitled: “Plant Proteomics: from the Molecular Basis of Biological Processes to a Systems Biology Perspective”, with guest editors Natalia Bykova, Andrei Igamberdiev and Christof Rampitsch. There will not be an open call for contribution to this issue, instead the call will be for INPPO conference participants only. All submissions will be peer-reviewed, with the deadline for submission on July 27th 2021. We strongly encourage you to submit and take advantage of this excellent opportunity to publish your research in a focused edition of a well-respected journal.
