:-) We would like to ask a question of general interest, as it might be the case in other studies. It is the first time I stumble upon this situation.
In our research, we have used the wild-type of a microbial strain and mutants for about 7 distinct genes. They were all subjected to different treatments and assessed by the same response variables. The seven genes, however, are not strictly related to each other, so that 3 of them as a group make-up one story, and the other 4 make-up a different one (thereby, two distinct manuscripts). The reason why they were all worked together (the wild-type and the mutants for these genes) were simply logistics and efficiency of resources usage.
One of the authors are concerned with the fact that for both papers with different groups of mutants (hence very different stories), the wild-type controls were the same! Therefore, he is afraid that using the same pictures and data in this case would configure a self-plagiarism issue between the two manuscripts.
Could you please help us on deciding whether this will indeed be an issue, or not?
Thank you very much in advance for your kindness and attention to this matter.
Best regards, Dr. Leandro.
