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. -
Red Ring Disease of Coconut Palms Is Caused by the Red Ring Nematode (Bursaphelenchus Cocophilus), Though This Nematode May Also Be Known As the Coconut Palm Nematode
1 Red ring disease of coconut palms is caused by the red ring nematode (Bursaphelenchus cocophilus), though this nematode may also be known as the coconut palm nematode. This disease was first described on coconut palms in 1905 in Trinidad and the association between the disease and the nematode was reported in 1919. The vector of the nematode is the South American palm weevil (Rhynchophorus palmarum), both adults and larvae. The nematode parasitizes the weevil which then transmits the nematode as it moves from tree to tree. Though the weevil may visit many different tree species, the nematode only infects members of the Palmae family. The nematode and South American palm weevil have not yet been observed in Florida. 2 Information Sources: Brammer, A.S. and Crow, W.T. 2001.

ABSTRACT Introduction: Rhodnius neglectus is a triatomine that colonizes different palm species. In this study, we aimed to describe the presence of this triatomine bug in the royal palms (Roystonea oleracea) in a rural region of the State of Goiás. Methods: Palm infestation was investigated by dissecting the palms or by using live-bait traps. Results: Two palm trees were infested by R. neglectus negative for Trypanosoma cruzi, the etiological agent for Chagas disease. In the study area, R. neglectus is frequently found in households. Conclusions: The adaptation of this species to palm trees introduced in Brazil for landscaping purposes poses another challenge for controlling the vectors of Chagas disease. Keywords: Triatomine bugs. Infestation. Palm trees. Rhodnius neglectus Lent, 1954 (Hemiptera, Triatominae) is palm trees such as gueiroba (Syagrus oleracea) and bacuri a triatomine bug that mainly inhabits palm trees in the Brazilian (Attalea phalerata) are widely found close to dwellings in this Savanna1-3, Pantanal, and Caatinga biomes4. -

Insect Egg Size and Shape Evolve with Ecology but Not Developmental Rate Samuel H
ARTICLE https://doi.org/10.1038/s41586-019-1302-4 Insect egg size and shape evolve with ecology but not developmental rate Samuel H. Church1,4*, Seth Donoughe1,3,4, Bruno A. S. de Medeiros1 & Cassandra G. Extavour1,2* Over the course of evolution, organism size has diversified markedly. Changes in size are thought to have occurred because of developmental, morphological and/or ecological pressures. To perform phylogenetic tests of the potential effects of these pressures, here we generated a dataset of more than ten thousand descriptions of insect eggs, and combined these with genetic and life-history datasets. We show that, across eight orders of magnitude of variation in egg volume, the relationship between size and shape itself evolves, such that previously predicted global patterns of scaling do not adequately explain the diversity in egg shapes. We show that egg size is not correlated with developmental rate and that, for many insects, egg size is not correlated with adult body size. Instead, we find that the evolution of parasitoidism and aquatic oviposition help to explain the diversification in the size and shape of insect eggs. Our study suggests that where eggs are laid, rather than universal allometric constants, underlies the evolution of insect egg size and shape. Size is a fundamental factor in many biological processes. The size of an 526 families and every currently described extant hexapod order24 organism may affect interactions both with other organisms and with (Fig. 1a and Supplementary Fig. 1). We combined this dataset with the environment1,2, it scales with features of morphology and physi- backbone hexapod phylogenies25,26 that we enriched to include taxa ology3, and larger animals often have higher fitness4. -

Chapter 2 Biology of the Papaya Plant
Chapter 2 Biology of the Papaya Plant Víctor M. Jiménez , Eric Mora- Newcomer , and Marco V. Gutiérrez-Soto Introduction The papaya plant ( Carica papaya L.) has been described with a large variety of adjectives, which acknowledge the structural and functional complexity and the high phenotypic plasticity of this giant tropical herb (León 1987 ). C. papaya , with a somatic chromosome number of 18, is the sole species of this genus of the Caricaceae, a family well represented in the Neotropics, that includes six genera with at least 35 species (Fisher 1980 ; Ming et al. 2008 ; Carvalho and Renner 2013 ). Most likely, papaya originated along the Caribbean coast of Mesoamerica (Fitch 2005 ) and spread to many tropical and subtropical regions around the world (Kim et al. 2002 ), where its distribution is limited by chilling sensitivity (Allan 2002 ; Dhekney et al. 2007 ). Domestication eventually led to substantial changes in vege- tative growth and sexual forms that distinguish wild populations from cultivated genotypes (Paz and Vázquez-Yanes 1998 ; Niklas and Marler 2007 ). Because of its high yield, nutritional value, functional properties, and year-round fruit production, the importance of this crop around the world is undeniable. The papaya plant is a semi-woody, latex-producing, usually single-stemmed, short-lived perennial herb. The relatively small genome of this species shows pecu- liarities in major gene groups involved in cell size and lignifi cation, carbohydrate economy, photoperiodic responses, and secondary metabolites, which place the papaya in an intermediate position between herbs and trees (Ming et al. 2008 ). Reproductive precocity, high photosynthetic rates of short-lived leaves, fast growth, V. -
United States Policy in the Hemisphere Influencing the State and Beyond
United States Policy in the Hemisphere Influencing the State and Beyond BY FRANK O. MORA AND BRIAN FONSECA nited States—Latin American and Caribbean (LAC) relations are strong, and more importantly, built on a broad base of sophisticated, organic relationships that extend Uwell beyond state-to-state engagements. Furthermore, U.S.-LAC relations encompass far more than what is often covered in the commentariat—like the number of presidential visits, the emergence of extra-hemispheric actors, problems related to drugs and immigration, or when compared to the visibility of U.S. engagements in others parts of the world. These outdated mea- sures fail to truly appreciate the complexity and depth of U.S.-LAC relations today, all of which are the result of our persistent and deliberate engagement with the Americas. As former Secretary of State Hillary Clinton argues, “the United States needs to build on the ‘power of proximity.’ It’s not just geography—it’s common values, common culture, and common heritage. Its shared interests that could power a new era of partnership and prosperity.”1 This article argues that in this context the role of the U.S. government must evolve from that of primary actor, to designer/ implementer of the enabling environment most conducive to the continued growth of organic, non-state relationships throughout the hemisphere, and offers a new set of measures that better reflects the strength of relations between the U.S. and its hemispheric partners. Deepening democratic principles, improving human security, and creating opportunities for economic growth and integration continue to be central to ensuring regional stability and advanc- ing our interests in the hemisphere. -
