I was recently invited to edit a special issue for Plants by the MDPI publisher. I know no one from my field in their editorial board. I have no experience with MDPI journals either but based on what I found in forums, they are very controversial. There are many cases when authors or reviewers experienced unprofessional practice during the review or editorial process, however, there are positive opinions, too. Indeed, there is high variation between journals. So, my question is specifically about Plants. All experiences are welcome.
