Study of the biological potential of in vitro extracts for Zeyheria tuberculosa (Bignoniaceae) Isabelle Souza de Mélo Silva, Raíssa Fernanda Evangelista Pires dos Santo, Naélia Monique Moreira Brito Silva, Andressa Leticia Lopes da Silva, Ingridy Viana Lucena, Andriele Mendonça Barbosa, Klebson Silva Santos, Thiane de Vasconcellos Costa Melo, Genilson Sarmento Lins Júnior, Francine Ferreira Pad...
Bignonia comprises 29 species of lianas characterized by eight phloem wedges, leaves usually 2-foliolate, mostly simple tendrils and opaque seed wings. The analysis of herbarium specimens in preparation for a taxonomic revision of the genus led to the recognition of two new species: (i) Bignonia cararensis from Costa Rica, characterized by a thyrse with lateral compound dichasia and lack of int...
UNLABELLED PREMISE OF THE STUDY New primers were developed for Bignonieae to enable phylogenetic studies within this clade using herbarium samples. • METHODS AND RESULTS Internal primers were designed based on available sequences of the plastid ndhF gene and the rpl32-trnL intergenic spacer region, and the nuclear gene PepC. The resulting primers were used to amplify DNA extracted from her...
Continuous measurements of sap fow have been widely used to measure water fux through tree stems and branches. However, these measurements lack the resolution necessary for determining fne-scale, leaf-level responses to environmental variables. We used the heat ratio method to measure sap fow rates through leaf petioles and leafet petiolules of saplings of the tropical tree Tabebuia rosea (Bign...
Tynanthus is a genus of lianas that is broadly distributed through the Neotropics. Two new species of Tynanthus from Brazil are here described and illustrated: Tynanthusdensiflorus, from Amazonas, and Tynanthusespiritosantensis, from Espírito Santo. Tynanthusdensiflorus is recognized by the conspicuous interpetiolar glandular fields, a feature rarely found in Tynanthus, and the dense thyrses. T...
