I normally use Mendeley for citing references in my research work. Normally, It will be like that, which is under American Sociological Association 6th Edition style.
Neuhaus, J. M., L. Sticher, F. Meins, Jr, and T. Boller. 1991. “A Short C-Terminal Sequence Is Necessary and Sufficient for the Targeting of Chitinases to the Plant Vacuole.” Proceedings of the National Academy of Sciences of the United States of America 88(22):10362. doi: 10.1073/PNAS.88.22.10362.
However, from the specific requirement of PNAS, they require under this style
J.-M. Neuhaus, L. Sticher, F. Meins, Jr., T. Boller, A short C-terminal sequence is necessary and sufficient for the targeting of chitinases to the plant vacuole. Proc. Natl. Acad. Sci. U.S.A. 88, 10362–10366 (1991).
I am wondering how to adjust the style of Mendeley to adjust the reference as requested? If not, is there anyway to do so automatically?
