  • The Developmental and Genetic Bases of Apetaly in Bocconia Frutescens

    The Developmental and Genetic Bases of Apetaly in Bocconia Frutescens

    Arango‑Ocampo et al. EvoDevo (2016) 7:16 DOI 10.1186/s13227-016-0054-6 EvoDevo RESEARCH Open Access The developmental and genetic bases of apetaly in Bocconia frutescens (Chelidonieae: Papaveraceae) Cristina Arango‑Ocampo1, Favio González2, Juan Fernando Alzate3 and Natalia Pabón‑Mora1* Abstract Background: Bocconia and Macleaya are the only genera of the poppy family (Papaveraceae) lacking petals; how‑ ever, the developmental and genetic processes underlying such evolutionary shift have not yet been studied. Results: We studied floral development in two species of petal-less poppies Bocconia frutescens and Macleaya cordata as well as in the closely related petal-bearing Stylophorum diphyllum. We generated a floral transcriptome of B. frutescens to identify MADS-box ABCE floral organ identity genes expressed during early floral development. We performed phylogenetic analyses of these genes across Ranunculales as well as RT-PCR and qRT-PCR to assess loci- specific expression patterns. We found that petal-to-stamen homeosis in petal-less poppies occurs through distinct developmental pathways. Transcriptomic analyses of B. frutescens floral buds showed that homologs of all MADS-box genes are expressed except for the APETALA3-3 ortholog. Species-specific duplications of other ABCE genes inB. frute- scens have resulted in functional copies with expanded expression patterns than those predicted by the model. Conclusions: Petal loss in B. frutescens is likely associated with the lack of expression of AP3-3 and an expanded expression of AGAMOUS. The genetic basis of petal identity is conserved in Ranunculaceae and Papaveraceae although they have different number of AP3 paralogs and exhibit dissimilar floral groundplans.

  • Session 5: Prospects for Weed Biological Control in Pacific Islands 206 Session 5 Prospects for Weed Biological Control in Pacific Islands

    Session 5: Prospects for Weed Biological Control in Pacific Islands 206 Session 5 Prospects for Weed Biological Control in Pacific Islands Weeds of Hawaii’s Lands Devoted to Watershed Protection and Biodiversity Conservation: Role of Biological Control as the Missing Piece in an Integrated Pest Management Strategy A. C. Medeiros and L. L. Loope U.S. Geological Survey, Pacific Island Ecosystems Research Center, Makawao, HI 96768 USA email: [email protected]; [email protected] Summary Despite Hawaii’s reputation as an extinction icon, significant biological resources remain, especially in watersheds, natural areas, and specialized edaphic sites (e.g., lava dry forest, coastal). While direct habitat destruction by humans continues, human-facilitated biological invaders are currently the primary agents of continuing degradation. The ability of invasive plants to have prolific seed production, efficient dispersal systems, and to become established in dense vegetation, complicated by Hawaii’s rugged topography, appears to render mechanical and chemical control as mere holding actions. Costly, ‘environmentally unfriendly’, and often ineffective, strategies using chemical and mechanical control on a large scale, despite the most valiant of efforts, can be viewed simply as attempts to buy time. Without increased levels of safely tested biological control, the seemingly inevitable result is the landscape level transformation of native forests, with potentially catastrophic consequences to cultural, biological, water, and economic resources. Increased levels of effective biological control for certain intractable invasive species appear to comprise a conspicuous ‘missing piece’ in our efforts to protect Hawaiian watersheds and other conservation lands. Evolution of Hawaiian Biota are all apparent drivers of the development of Hawaii’s renowned biota and perhaps its relative vulnerability to invasions (Loope, 2011).
  • Survey for Natural Enemies of Bocconia Frutescens in Costa Rica

    Survey for Natural Enemies of Bocconia Frutescens in Costa Rica

    252 Session 5 Prospects for Weed Biological Control in Pacific Islands Survey for Natural Enemies of Bocconia frutescens in Costa Rica K. Nishida1 and M. T. Johnson2 1Universidad de Costa Rica, Escuela de Biología, San José, Costa Rica [email protected] 2USDA Forest Service, Pacific Southwest Research Station, Institute of Pacific Islands Forestry, Volcano, HI, USA Abstract Bocconia (Bocconia frutescens L.) (Papaveraceae) are small trees up to 6 m tall native to the Neotropics. Bocconia has established populations on the islands of Maui and Hawaii, spreading from dense groves in disturbed sites to invade native dryland and mesic forests, where it is considered a threat to rare endemic organisms. Bocconia is recognized as a noxious weed by the State of Hawaii, making it a target for eradication on islands where it is not already established. Mechanical and chemical controls have been pursued in some areas, but are prohibitively expensive over its present wide distribution. Bocconia is found in a variety of habitats in biodiversity-protected land of Costa Rica, typically colonizing disturbed areas such as tree falls and landslides but without displaying invasiveness. Plants in this native range were explored for insects and other natural enemies between December 2008 and September 2009. On monthly survey trips habitat and plant conditions were noted, and its natural enemies were photographed and collected for rearing and identification. A total of 38 species of natural enemies have been documented (35 insects, one mite, one phytoplasma and one fungus). Thus far only three potential control agents are recognized: a gregarious leafminer (Liriomyza sp.) (Agromyzidae), a treehopper (Ennya pacifica Fairmaire) (Membracidae) which deposits egg masses in leaf veins and inflorescence stems, and an unidentified leaf tier moth (Tortricidae) whose larvae damage young leaves.

    ROADSIDE SURVEY AND EXPERT INTERVIEWS FOR SELECTED PLANT SPECIES ON LANAI, HAWAII Funded by: The Hawaii Invasive Species Council and the Maui Invasive Species Committee Prepared by: Forest Starr 1, Kim Starr 1, and Lloyd L. Loope 2 1Pacific Cooperative Studies Unit, Dept. of Botany, University of Hawaii, Honolulu, HI 96822 2U. S. Geological Survey, Pacific Island Ecosystems Research Center, P.O. Box 369, Makawao, Maui, HI 96768 2007 INTRODUCTION Invasive plant species pose a threat to Hawaii's economy, ecology, and way of life. Early detection and rapid response is one method used to minimize the damage caused by invasive species. It is hoped that by finding and removing weeds before they become widespread and out of control, that overall control costs will be reduced, removal efforts will be more feasible, and damage to resources will be minimized. The Maui Invasive Species Committee (MISC) works to prevent, detect, and remove plant species early as part of their overall strategy to combat invasive weeds. MISC is based on the island of Maui, but also conducts work throughout Maui County which includes the islands of Molokai, Lanai, and Kahoolawe. To assist in their early detection efforts on Lanai, we conducted a roadside survey and expert interviews for selected target plant species. Roadside surveys and expert interviews have proven to be a useful way to detect incipient invasive plants in Hawaii (Starr et al. 2003a). Previous surveys of this nature were conducted on Maui in the years 2000-2001 (Starr et al. 2006a) and on Molokai in 2005 (Starr et al. 2005).
