Lohmann Dedico esta tese, com muito amor e gratidão, ao Eduardo por ter me dado todo apoio, incentivo e ter sonhado junto comigo ... “Morphological innovations of land plants have profoundly changed the terrestrial biosphere. Plant innovations have affected global geochemistry, hydrology, atmospheric composition and the evolution of other biota. The study of plant evolution can therefore be viewed as a study of the way in which nucleotide changes have affected the functioning of the planet. These innovations result from alterations in the original developmental pathways responsible for the relatively simple construction of early land plants....” Quentin C. B. Cronk Segue o teu destino, Rega as tuas plantas, Ama as tuas rosas. O resto é a sombra De árvores alheias.

    Biological Control of Cape ivy Project 2004 Annual Research Report prepared by Joe Balciunas, Chris Mehelis, and Maxwell Chau, with contributions from Liamé van der Westhuizen and Stefan Neser Flowering Cape ivy overgrowing trees and native vegetation along California’s coast near Bolinas United States Department of Agriculture - Agricultural Research Service Western Regional Research Center - Exotic & Invasive Weed Research Unit 800 Buchanan St., Albany, California 94710 (510) 559-5975 FAX: (510) 559-5982 Executive Summary by Dr. Joe Balciunas This is our first attempt at an ‘electronic’ report, and most of you will receive our Annual Report for 2004 as PDF attachment to an email. We hope that this will make our report more easily accessible, since you may chose to store it on your hard disk. We made solid progress during 2004 towards our goal of completing our host range testing of our two most promising potential biological control agents for Cape ivy. We overcame a summertime ‘crash’ of our laboratory colonies, and by year’s end had strong colonies of both the gall fly, Parafreutreta regalis, and the stem-boring moth, Digitivalva delaireae. By the end of 2004, we had tested more than 80 species of plants, and neither of our candidate agents was able to complete development on anything other than their Cape ivy host. The single dark cloud has been the continuing downturn in external funds to support our Cape ivy research, especially that conducted by our cooperators in Pretoria, South Africa. While we have managed to maintain a small research effort there, our cooperators are no longer assisting us in our host range evaluations.

  • 1 Metabolitos Secundarios Con Actividad Antifúngica En La Tribu
    Metabolitos secundarios con actividad antifúngica en la tribu Senecioneae (Asteraceae) García Contreras, María Paula1 [email protected] 1.Pontificia Universidad Javeriana. Facultad de Ciencias. Unidad de Investigaciones Agropecurias (UNIDIA). Grupo de investigación en fitoquímica (GIFUJ) RESUMEN Los hongos patógenos de plantas representan grandes pérdidas para el sector floricultor y su tratamiento se ha visto limitado debido a la toxicidad de los fungicidas y al desarrollo de mecanismos de resistencia por parte de los patógenos. Los metabolitos secundarios de las plantas se han estudiado como una potencial alternativa para su tratamiento debido a su efectividad como sustancias antimicrobianas, particularmente dentro de la familia Asteraceae, la tribu Senecioneae se ha mostrado como un grupo potencial para la búsqueda de metabolitos secundarios con actividad biológica. Por lo tanto, el propósito de esta revisión es recopilar los estudios disponibles de actividad antifúngica para la tribu Senecioneae con el fin de identificar potenciales compuestos para la investigación en fungicidas naturales aplicables a fitopatógenos de cultivos de flores. Palabras clave: Asteraceae, Senecioneae, metabolitos secundarios, fitoquímica, aceites esenciales, monoterpenos, sesquiterpenos, alcaloides pirrolizidínicos, actividad antifúngica, fitopatógenos. INTRODUCCIÓN Las plantas son susceptibles a una gran variedad de agentes bióticos que pueden afectar su crecimiento, desarrollo y reproducción. Dentro de estos, los hongos patógenos tienen la capacidad de infectar tejidos como la raíz y el tallo, dificultando el transporte de agua y nutrientes, o las hojas, impidiendo procesos de intercambio gaseoso y fotosíntesis (Struck 2006). Debido a que estos patógenos pueden atacar plantas de interés económico como los cultivos de flores y generar grandes pérdidas (Cámara de Comercio de Bogotá 2015), los productores acuden a estrategias rápidas y sencillas para su tratamiento como la aplicación y rotación de fungicidas sobre los cultivos (Lesmes-Fabian & Binder 2013).

The good news is that by the end of 2006, we had reached the milestone of completing our host range testing of our two most promising potential biological control agents for Cape ivy, the gall fly, Parafreutreta regalis, and the stem-boring moth, Digitivalva delaireae. We have tested more than 80 species of plants, and neither of our candidate agents was able to complete development on anything other than their Cape ivy host.{See sections II & III] We have collated our results, and are preparing a formal ‘petition’ seeking permission to release both of these agents in the field. This ‘petition’ will be submitted to TAG during the second quarter of 2007. We hope to receive a positive recommendation from TAG within 6 months.

Some floral micromorphological characters of this species, including shape of anther bases, configuration of anther collars, and anther endothecial tissue cell wall thickenings, are confirmed to perfectly match those of Senecio and this has obviously resulted in the placement of the species within that genus. Chromosome counts indicate S. kumaonensis has 2n = 40, a number common to Senecio and Synotis but not occurring in Parasenecio (the cor- rect generic name for the Asian species previously referred to Cacalia), which has 2n = 52, 58, and 60. The presence of six subterminal-centromeric (st) chromosomes in the karyotype of S. kumaonensis, however, lends strong support to the close relationship of this species to Synotis.

  • 1 Supplement 1.1 Detailed Explanation of Phylup Options 1.1.1 Defining the Mrca
    1 Supplement 1.1 Detailed explanation of PhylUp options 1.1.1 Defining the mrca If the user wants to update the alignment either to beyond the current sampling of the data or only to a subclade of the input, they can define the mrca of the clade of interest in the configuration file by providing the NCBI taxon identifier. If the user provides no mrca, the tool calculates the mrca of all input sequences. Overall, the setting of the mrca needs to be handled with care. If the group of interest is not monophyletic but defined as being monophyletic in the NCBI taxonomy, closely related sequences are not added. It is possible to add several mrca (e.g. mrca = NCBI taxonid1, NCBI taxonid2, NCBI taxonid3) or to choose the next higher monophyletic node to account for this issue that is related to the ncbi taxonomic database. For example, the genus Senecio in its current circumscription contains genera that were not part of the genus before, plus many species that were defined to belong to the genus are actually only distantly related to the genus (Pelser et al., 2007). To focus on the genus Senecio in its current circumscription (Senecio s.str.), one can define all NCBI taxon IDs for the genera that are nested within Senecio: Hasteola Raf., Lasiocephalus Willd. ex Schltdl., Iocenes B.Nord., Aetheolaena Cass., Culcitium Humb. & Bonpl. and Robinsonia DC. This ensures to get all the sequences for the group of interest, but will also add Senecio species, that are actually only distantly related to Senecio s.str.

Box 50007 SE-104 05 Stockholm, Sweden; and 7 Johannes Gutenberg-Universit ä t Mainz, Institut f ü r Spezielle Botanik und Botanischer Garten, 55099 Mainz Germany One of the longstanding questions in phylogenetic systematics is how to address incongruence among phylogenies obtained from multiple markers and how to determine the causes. This study presents a detailed analysis of incongruent patterns between plastid and ITS/ETS phylogenies of Tribe Senecioneae (Asteraceae). This approach revealed widespread and strongly supported incongruence, which complicates conclusions about evolutionary relationships at all taxonomic levels. The patterns of incongru- ence that were resolved suggest that incomplete lineage sorting (ILS) and/or ancient hybridization are the most likely explana- tions. These phenomena are, however, extremely diffi cult to distinguish because they may result in similar phylogenetic patterns. We present a novel approach to evaluate whether ILS can be excluded as an explanation for incongruent patterns.
