Microwave irradiation is a suitable method for caulerpin extraction from the green algae Caulerpa racemosa (Chlorophyta, Caulerpaceae)

Autor: Sarah de J. Cantarino, Angélica Ribeiro Soares, Ricardo Coutinho, Sabrina T. Martinez, Heitor M. Duarte

Publikováno v: Natural Product Research. 36:2149-2153

Caulerpin is a bisindolic alkaloid that has been obtained from many species of the genus Caulerpa. The main objective of this paper is to evaluate four extraction methods of caulerpin in the C. rac...

The sea-hare Aplysia brasiliana promotes induction in chemical defense in the seaweed Laurencia dendroidea and in their congeneric neighbors

Autor: Manuel Norte, José J. Fernández, Renato Crespo Pereira, Nathália Nocchi, María L. Souto, Angélica Ribeiro Soares, Heitor M. Duarte

Publikováno v: Plant Physiology and Biochemistry. 154:295-303

Inducible chemical defenses are more common in temperate seaweeds than tropical ones, and are directly detected by increase of chemical contents, or indirectly by differential consumption of live seaweed tissues or artificial food with algal extracts

Autor: Itabajara da Silva Vaz, Daniel Luiz Reis Simas, Heitor M. Duarte, Christiano Calixto Conceição, Angélica Ribeiro Soares, Jorge Moraes, Jhenifer Nascimento da Silva, Carlos Logullo, Renato Martins da Silva

Publikováno v: Metabolomics. 17

Metabolomic approaches can assess the actual state of an organism’s energy metabolism during a specific morphological event, providing a more accurate insight into the correlations between physiology and metabolic regulation. The study of the metab

Differential susceptibility of distinct parts of the aquatic plant Nymphoides humboldtiana to herbivory supports the optimal defense theory

Autor: Renato Crespo Pereira, Tatiana Ungaretti Paleo Konno, Nathália Nocchi, Angélica Ribeiro Soares, Heitor M. Duarte, Etiene E. G. Clavico

Publikováno v: American journal of botanyREFERENCES. 108(11)

PREMISE The optimal defense theory (ODT) predicts that the allocation of chemical defenses in plants will be concentrated in parts or tissues that are of higher fitness value for the individuals that produce them. Chemicals are known to be allocated
