Acta Botanica Brasilica (Acta bot. bras.) publishes original articles on all aspects of plant (including algae) and fungi biology. The submitted manuscript or its essential content must not have been published previously or be under consideration for publication elsewhere. Contributions should be substantial, written in high-quality English and show general interest. Manuscripts that report aspects of local interest are discouraged unless the implications of the findings are wide-reaching. Manuscripts with agronomic subjects are expected to contain a substantial amount of basic plant biology.
