SPRING 2014 7 FROM THETO GARDEN THE LABORATORY THE SEARCH FOR NATURAL COMPOUNDS By Maria-Luisa Veisaga Christopher Chin Horacio Priestap, Ph.D. Javier Francisco-Ortega, Ph.D. Brett Jestrow, Ph.D. Tracy Commock Keron Campbell M.

Some of the most exciting research is in collections of tropical plants. natural plant products and their utility in medicine, agriculture and taxonomy. Because of South Florida’s For centuries, communities have understood the beneficial health effects of some plants, commonly climatological conditions employing them for their healing properties. In many places in the world, plants are central to health and Fairchild’s horticultural care and as a source of medicine. About half of the pharmaceuticals in use today are derived from natural tradition, tropical plants plant products. The search for new therapies has driven the study of many traditional medicinal plants, leading can be grown throughout to discoveries of bioactive compounds and molecules the year. The unique with beneficial properties. These compounds can also be valuable for plant environmental setting lends classification. Indeed, a discipline known as “chemotaxonomy” searches for compounds with unparalleled opportunities for discriminatory value among species. Many of these compounds evolved to help the plant combat infections research and study of tropical of fungi and bacteria, and therefore may have anti- pathogenic effects for human health. Consequently, plants during their different these compounds’ metabolic pathways—the sequences of biochemical reactions that occur in all living growing stages. cells—can reveal clues about the origin of the plants’ adaptations and their evolutionary history. Plant Product Research at Fairchild and FIU Several fields of research come together to work on unraveling these clues. Phytochemical research looks at plants’ organic components and helps to identify secondary compounds the plants produce. Cellular and molecular biology, together with biomedical tools, determine the metabolic pathways of compounds with potential medical applications, as well as the genes governing these metabolic routes. Within the framework of the Convention on Biological Diversity agreements, Florida International University cellular biologists and botanists and Fairchild scientists have developed three projects to research the natural products of plants—looking at members of the genera Artemisia, Portlandia and Aristolochia. Our initial efforts show that the isolated compounds have medicinal potential and can be useful in taxonomic research. Dr. Horacio Priestap (left) and Christopher Chin (right) examine data related to bioactive compounds of Portlandia (Rubiaceae) in Alejandro Barbieri’s lab at FIU. Photo by M. L. Veisaga Many species of the genus Artemisia, a member of the sunflower family with almost 400 species, have ample traditional medicinal uses in both the Old and New Worlds. Native Americans use several species for malaria treatment and bacterial infections, as well as for fever, stomach and inflammatory disorders. Indeed, the compound Artemisinin is commonly used as a drug principle to treat malaria. Our research focuses on A. douglasiana (known as California mugwort or Douglas’s sagewort) and A. tridentata subsp. vaseyana (mountain big sagebrush). These three taxa have two particular compounds, known as dehydroleucodine and dehydroparishin–B, that have shown extraordinary anti-tumor activity against cultured invasive human breast cancer and melanoma cancer cells. The Jamaican genus Portlandia belongs to the coffee plant family Rubiaceae—a family that is renowned for its natural products. This highly ornamental genus has seven species. Our research with this group of plants is being done in partnership with the Institute of Jamaica and in collaboration with colleagues from the U.S. Department of Agriculture who will provide assistance with computational analyses of the data we gather.

The study of plant products will bring a new dimension to Fairchild’s living collections. t will not only enhance scientic research but, importantly, will help nd natural products with agricultural The approximately 700 species of the genus Aristolochia (Aristolochiaceae) are cultivated as ornamentals and and medicinal values. mostly distributed along tropical and subtropical regions of the world. They had been used in traditional medicine because of their curative properties for diseases, including inflammatory disorders, rheumatism, wounds and skin diseases, and also for intestinal worms. However, some species were found to be nephrotoxic (toxic to the kidneys) and carcinogenic. For instance A. clematitis (birthwort), A. fangchi, and A. manshuriensis have been intensively studied because of the aristolochic acid that they produce. Several observations suggest that this acid forms a unique intermediate compound that can lead to renal failure. Fairchild’s founders envisioned that the Garden’s living collections would be instrumental for research, horticulture and education. During the last few decades the collections have been critical in Fairchild’s anatomical, morphological, horticultural and ecological research. These collections have also been widely used by tropical botanists and horticulturists from all over the world. Since the establishment of the Fairchild-FIU molecular laboratory 12 years ago, these collections have been at the core of our plant classification and conservation studies. The study of plant products will bring a new dimension to the Garden’s living collections.

Biological invasions are an important component of human-caused global environmental change. Invasive alien species are now a major focus of global conservation concern. The decisions need to be made on whether benefits derived from the invasive spread of an alien species outweigh the reduced value of ecosystem services, e.g. the loss of grazing land in areas invaded with Lantana camara and Senna occidentalis . It is necessary to consider actions to deal with the current problems caused by invasive species and to reduce the magnitude of the problem in the future. The present catalogue on invasive alien plant species of the northwestern & Western Ethiopia is therefore timely one. It focuses on some species of invasive alien plants in Ethiopia. These include the most serious invasives, such as Alternanthera philoxeroides, Cassia uniflora, Chromolaena odorata, Eichhornia crassipes, Lantana camara, Parthenium hysterophorus, Senna obtusifolia and others. I am confident that this publication will be immense value to foresters, environmentalists, field researchers and conservation managers to pay attention on the ecological impact of invasive aliens both at the species and at the ecosystem levels.

Exhibit 14 – Maya Cocoa Garden Introduction This new Catalog of the trees and plants of the Gifford Arboretum has been in the works for over years. It has been a labor of love, but also much more difficult than anticipated. Part of the difficulty has been taxonomic upheaval as genetic analysis has reordered the taxonomy of many plant species. However, that also makes the catalog all the more timely and needed. It includes plot maps and cross references to hopefully increase its value to users, and it has been paired with the creation and installation of new identification tags that include QR codes for all plants in the Arboretum. These codes allow guests to learn about WKH plants right as they stroll through the Arboretum. QR reader apps are free andHDV\ WR download WR D smart phone, DQGWKH\ greatly increase the educational value of the Arboretum to you Special thanks are due to WKRVH who worked on the new Catalog, including Aldridge Curators Anuradha Gunathilake, Wyatt Sharber, Luis Vargas, DQG &KULVWLQH 3DUGR as well as volunteers and members of the Gifford Arboretum Advisory Committee, Julie Dow and Lenny Goldstein.
