Plant Biosystems is the research journal edited by the Società Botanica Italiana. Published six times a year, the journal is open to papers dealing with all aspects of plant biology, systematics, and ecology. Research studies containing novel and significant findings, from the molecular level to ecosystems and from micro-organisms to flowering plants, are welcome. Plant Biosystems succeeded " Giornale Botanico Italiano", the historical journal of the Società Botanica Italiana, from the year 1997. Plant Biosystems has been conceived in consideration of the recent progress in botanical research. An editorial board has been devised to ensure that all the main trends of contemporary plant science are represented. Manuscripts are classified as Full Paper, Review, ‘Data Note, and Rapid Report or Short Communication'. A Rapid Report is intended for publication, in a concise form, of new and relevant findings. The classification as Rapid Report is determined by the Editor. A Short Communication (no more than two printed pages) is for a concise but independent report. It is not intended for publication of preliminary results. An international panel of highly qualified referees warrants the highest scientific standard.
