Última Beyond pollination: diversity of secretory structures during flower development in different legume lineages Acta Botanica Barros,Thais Cury De; Marinho,Cristina Ribeiro; Pedersoli,Giseli Donizete; Paulino,Juliana Vilella; Teixeira,Simone Pádua. ABSTRACT Floral secretory structures are usually associated with the attraction of pollinators, but may also play an important role in the mechanisms of plant protection. This study aimed to show the diversity of secretory structures present in the developing flowers of 15 legume species belonging to different clades and to associate them with functions other than the pollinator attraction. Buds, flowers and developing axis of inflorescence were processed for surface, histological, and ultrastructural analyses. The species investigated displayed a wide diversity of secretory structures in developing flowers such as phenolic cells and/or tissues, mucilaginous cells, secretory cavities, secretory trichomes and colleters. Each type of secretory structure...

Caliciopsis (Leguminosae-Caesalpinioideae): anatomy and taxonomic implications Acta Botanica Silva,Marinalva dos Santos; Coutinho,Ítalo Antônio Cotta; Araújo,Maicon Nascimento; Meira,Renata Maria Strozi Alves. ABSTRACT The genus Chamaecrista contains ca. 330 species organized into six sections, of which section Chamaecrista is the second largest (ca.75 species) distributed among six series, while the section Caliciopsis contains only two species. Colleters have been described in the genus Chamaecrista and they show potential taxonomic and phylogenetic significance. They are associated with lubrication, desiccation prevention and protection from microbial attacks of young developing organs. Although six types of colleters have been described for the genus Chamaecrista, there have been no studies focusing on the diversity of colleters in the sections Chamaecrista and Caliciopsis. Samples from developing leaves and flowers of both sections were obtained from...
