Abstract

The shoot system, which consists of the stem and leaves, has been subject of recent research in anatomy and molecular biology, especially in regard to the leaf development. In this sense, this research addresses issues related to the leaf ontogeny, including anatomical and molecular aspects, within groups of plants not yet studied in the literature and that lack important information. The selected taxa are representatives of large groups of vascular plants: ferns, monocotyledons and eudicotyledons. As sub-themes will be investigated aspects of (i) establishment and transition of the determination of leaf primordia; (ii) growth regions in dorsiventral and teretes leaves and (iii) development of structures in the leaf base and its structural homology. Conventional techniques in plant anatomy will be used, such as optical and scanning electron microscopy. In addition, gene expression will be performed by using in situ hybridization for target genes related to leaf development. Highly relevant results are expected to study the primary shoot system in different groups of vascular plants, with original scientific publications, as well as promoting academic cooperation for the exchange of students and teaching staff/researchers.
