Format

All papers must be written in English. We strongly suggest to ensure that the language is corrected before submission.
The International System of units (SI) must be adopted for all numerical data. Whenever abbreviations are to be used, the names should be given initially in full with the abbreviation in parentheses, e.g. polyacrylamide gel electrophoresis (PAGE), Tobacco mosaic virus (TMV). The CBE manual Scientific Style and Format (6th edition, Cambridge University Press) is recommended as a reference for style and conventions.
Double spacing and continuous line numbering should be used throughout the text and in the figure legends.

Title page
This page should contain: title of the paper; name(s), affiliation(s), and full address(es) of all author(s); name of the corresponding author, with fax number and e-mail address, and the running title.

Summary
The Summary (max 250 words) should be concise so as to describe briefly the scope of the study, the major results and conclusions. It should not contain references.

Introduction
This section should give background information on the extant study in a concise form. Extended review of the subject should be avoided as well as any anticipation of results.

Materials and Methods
The Materials and Methods section is divided into subsections. It should give enough information to allow other investigators to repeat the experiments. For standard procedures a reference is sufficient. Only major modifications or novel methods should be detailed. Suppliers of reagents or equipments should be indicated in parentheses. The source of bioreagents (e.g., bacterial strains, virus isolates, antibodies, ecc.) should also be specified.

Results
This section may be divided into subsections. The rationale for the experiments and the results should be clear and concise. The interpretation of data should be presented in the Discussion section.

Discussion
The Discussion should give an interpretation of the results, related to previous work. It should not be a mere repetition of the results. Results and Discussion sections may be combined.

Acknowledgements
Optional. Beside personal recognitions, it may contain the source of financial support obtained for the study.

References
Literature citations in the text should be in parentheses, giving the author's name and date, and using et al. , when the number of authors exceeds two [e.g. (Smith, 1994); (Smith and Pearson, 1991); (Smith et al., 1995)]. Citations of personal communications and unpublished data are allowed, but only when strictly necessary. References must be listed in alphabetical order by first author and written in the following formats according to where they are from:
